Next Chevy Malibu?

Tim Howard — Fri, 12 Mar 2010 02:15:55 +0000

Patent drawings of what is said to be the 2012 Chevrolet Malibu have popped up online. Despite the lack of detailing in the sketches, the styling on this “potential” Malibu looks promising. It’s bolder and more angular than the current Malibu and features a tail-end (including the lights) that is reminiscent of the current Camaro’s end.

If fact, a GM representative claimed a while back that the Next Chevy Malibu would share styling cues with the Camaro. Folks, we might just be looking at the real deal, and we like it.

Chevrolet Cruze Coupe?

Tim Howard — Thu, 11 Mar 2010 17:36:04 +0000

A Chevrolet Cruze coupe was the last thing on my mind, but as GM’s global compact car, a Cruze coupe make a lot of sense. After all, the Cobalt has a coupe variant. In a live webchat earlier this week, president of General Motors North America, Mark Reuss, was asked whether or not there will be a Chevrolet Cruze coupe in the future. He responded:

2 door cruze is a nice idea, and it may show up in the global market. As we have 2 door Cobalts currently, NA would naturally look at a Cruze 2 door, but I believe our small car portfolio will be WAY beyond what it is now, so a 2 door something still is needed.

We think a two-door Cruze has the potential to look good, moreso than the Cobalt coupe. Now only if GM agrees to make an SS Cruze, because we all know how spectacular the Cobalt SS was.

New (2011) GMC Seirra Denali HD

Kwame Owusu — Thu, 11 Mar 2010 16:00:35 +0000

What’s a new Chevrolet Silverado lineup without a new GMC Sierra lineup to match it? The 2011 Serrea Heavy-Duty lineup has been revealed and will offer a high-end Denali version, a first for a heavy-duty GMC pickup.

Besides the extra chrome and other minor touch-ups on the exterior, the 2011 Sierra Heavy Duty lineup is technically identical to its 2011 Silverado Heavy Duty sibling. No surprise there. It is powered by either the same Vortec 6.0L gasoline V8 making 360HP and 380 lb-ft of torque or the 6.6L Duramax turbo-diesel V8 producing 397HP and 765 lb-ft of torque. The 6.0L gasoline V8 is mated to a Hydra-Matic 6L90 6-speed automatic transmission while the 6.6L Duramax diesel is mated to a new Allison 1000 6-speed automatic.

Like its Chevrolet counterpart, the 2011 GMC Sierra Heavy Duty pickups are offered in 2500HD and 3500HD versions. They also offer segment-best towing (20,000 lbs) and payload (6,335 lbs). Detailed specifications can be found in GMC’s press release.

PRESS RELEASE:

Sierra Denali HD Leads New 2011 Sierra Heavy-Duty

ST. LOUIS, Mo. – GMC today announces the new 2011 Sierra Denali HD, the first offering of the exclusive Denali line on a heavy-duty GMC pickup. The Sierra Denali HD leads a comprehensively redesigned lineup of 2011 Sierra 2500HD and 3500HD trucks that go on sale in early summer – including the most powerful diesel engine in the segment.

Sierra HD’s new 6.6L Duramax turbo diesel delivers 397 horsepower (296 kW) at 3,000 rpm and 765 lb.-ft. of torque (1,037 Nm) at 1,600 rpm.

“The new Sierra Denali HD is the latest expression of GMC’s Denali philosophy of blending capability with premium features and styling,” said Lisa Hutchinson, GMC product marketing director. “It is a premium tool that offers many comfort and infotainment features, along with a maximum towing capacity of 15,600 pounds with the segment’s most powerful diesel – that’s enough to tow a 34-foot-long, three-axle travel trailer.”

The Sierra Denali HD comes exclusively on the 2500HD chassis, in a 4WD crew cab standard box configuration. A Vortec 6.0L gas V-8/six-speed automatic powertrain is standard and the new Duramax 6.6L turbo diesel/Allison 1000 six-speed transmission powertrain is available.

The iconic Denali four-bar, chrome grille with round air inlets distinguishes the Sierra Denali HD on the outside, along with body-color bumpers, chrome door handles, chrome accents and 18- and 20-inch polished forged aluminum wheels.

The balance of the new 2011 Sierra HD lineup is identified on the outside by new, three-bar grilles and powertrain-badged louvered hoods, along with a revised, full-width chrome steel front bumper and a new family of 17-, 18- and 20-inch wheels. It’s beneath the skin, however, where they are truly separated from their predecessors – and the competition. Highlights include:

* Increased towing capability (20,000 lbs./9,072 kg) and payload (6,335 lbs./2,873 kg) supported by all-new fully-boxed, high-strength-steel frames and strong suspensions for maximum capability and exceptional ride characteristics
* Five of the 12 3500HD models offer a payload capability greater than 6,000 pounds vs. Ford Super Duty’s single model greater than 6,000 pounds
* Thirteen of the 22 2500HD models offer a payload capability greater than 3,100 pounds vs. Ford Super Duty’s single model greater than 3,100 pounds
* New 6.6L Duramax diesel delivers segment-best power, up to 11-percent greater highway fuel economy, up to 63-percent lower emissions, B20 biodiesel capability and quicker acceleration
* Larger gas tank and fuel economy improvements allow up to 680 miles (1,090 km) between fill-ups with the 6.6L Duramax turbo diesel
* All-new “smart” exhaust brake feature provides greater control on grades and reduced brake pad wear
* An array of control features, including trailer sway control, integrated trailer brake control, hill start assist, automatic grade braking, intelligent brake assist and larger brakes
* Purposeful technology, including available mobile WiFi, USB connectivity, Bluetooth connectivity, XM Satellite Radio, OnStar 9.0 and navigation.

“GMC has been one of the industry’s strongest truck brands for more than 100 years, and we back the 2011 Sierra HDs with a comprehensive five-year/100,000-mile powertrain warranty that provides the best coverage in America,” said Hutchinson. “From the segment-best diesel power to the segment-best warranty, these trucks deliver strength and peace of mind on all fronts.”

Following are details of the new and redesigned product features of the Sierra Denali HD and the other Sierra 2500HD and 3500HD models.

The Sierra HD lineup brings greater capability.

The details: Depending on the model, Sierra HD models offer:

* Increased fifth-wheel towing capacity of 20,000 pounds (9,072 kg)
* Conventional towing capacity increases up to 23 percent, with a maximum of 16,000 pounds (7,272 kg)
* Improved payload capability of 6,335 pounds (2,873 kg) on a complete vehicle
* Gross Combined Weight Rating increases to 27,500 pounds (12,500 kg)
* Gross Vehicle Weight Ratings increases up to 17 percent to 13,000 pounds (5,909 kg)

* Front Axle Weight Rating increases by up to 25 percent to 6,000 pounds (2,721 kg)
* Snow plow capability for all 4WD cab configurations.

“You can see by the ratings numbers that the Sierra HD lineup is more capable, but the trucks are also better performers in the intangible qualities that bond owners with their trucks,” said Rick Spina, vehicle line executive. “They accelerate quicker – especially when fully loaded – stop more confidently and deliver a smooth, quiet driving experience that you have to experience to fully appreciate.”

The new 2011 Sierra Denali pairs capability with premium features.

The details: The new Sierra Denali HD is offered exclusively in the Crew Cab standard box configuration on the 2500HD chassis, providing a spacious cabin with room for up to five. As with other Denali models, including the new Acadia Denali, the cabin is unique with standard premium touches. It includes Denali-specific brushed aluminum trim, power-adjustable pedals, a Bose premium surround audio system and 12-way power seats. Along with an optional heated steering wheel, heated and cooled leather-appointed seating is available. The exterior is offered in three colors: Black, Stealth Gray and White.

On the capability front, the Sierra Denali has a gross vehicle weight rating (GVWR) of 10,000 pounds (4,536 kg), a payload capacity of 2,959 pounds (1,342 kg) and a maximum trailering rating of 15,600 pounds (7,076 kg) with a fifth-wheel hitch. The maximum conventional hitch trailering rating is 13,000 pounds (5,897 kg).

Engineers developed 11 all-new, fully boxed frame assemblies to improve durability and ride characteristics and support increased capabilities.

The details: The frames have increased cross sections and use more high-strength steel for greater durability, higher towing capacity and improved ride and handling; the front sections are hydroformed. The bending and beaming stiffness of the frames is increased 92 percent and 20 percent, respectively, with the fully boxed sections enhancing torsional stiffness by a factor of five. Also, larger engine and transmission mounts, coupled with a 125-percent-stiffer front frame structure, provide greater vibration control, while hydraulic body mounts are incorporated under the cab section on extended and crew cab models for a more isolated feel inside. Engineers addressed common customer and aftermarket uses when designing the new frames, including adding access holes to the rear frame section to enable easier installation of fifth-wheel/gooseneck-style hitches. Also, the frame-mounted hitch for conventional trailering is stronger, with a box-tube design. It supports up to 16,000 pounds (7,257 kg).

Sierra HDs feature a new, stronger independent front suspension – enabling snow plow installation on all 4WD models.

The details: A completely redesigned independent front suspension system offers up to a 25-percent greater front axle weight rating – up to 6,000 pounds (2,721 kg) front gross axle weight rating (FGAWR) – so a snow plow can be used on all 4WD cab configurations with the available snow plow prep package. Sierra’s signature short-long arm/torsion bar front suspension design is retained, but now features new, forged steel upper control arms that are stronger and lighter than their predecessors. The new lower control arms are made of precision-machined cast iron to handle the greater loads. Five different torsion bar rates support five different front gross axle weight ratings (a single torsion bar was previously used for all models). This helps stabilize the range of trim heights of various models under load, while enhancing appearance, handling, durability, tire wear and alignment. The trim height is adjusted on each bar via a single bolt, easily allowing the height to be changed to account for the weight of a snow plow or other accessories. The Sierra HD front suspension now uses a pair of urethane jounce bumpers on each side, instead of one, for improved load management; and there’s a new upper shock mount attachment design that’s positively connected to the frame with two fasteners. This design eliminates squeaks and clunks, while supporting higher load capability and increased durability.

COMPETITIVE FACTS: Compared to competitors’ beam-axle front suspensions, the Sierra’s independent front suspension provides a better ride, more accurate trim height control (with fewer parts) and greater flexibility to adjust the alignment for weight and tire sensitivity.

A new asymmetrical leaf-spring rear suspension supports greater loads.

The details: Matching the Sierra HD’s greater strength and capability is a rear suspension designed to support greater loads. It features a new, larger asymmetrical leaf-spring design that also contributes to improved ride and handling characteristics. The asymmetrical design is derived from unequal front and rear spring half lengths, which minimize axle hop and enhance traction control efficiency. 2500HD models feature a two-stage leaf-spring design, while 3500HD models have a three-stage design. All models feature 3-inch-wide (76 mm) leaf springs that are 20-percent wider than previous models. The larger leaf-spring design supports increased rear gross axle weight ratings across the board. On the 2500HD models, the rating is 6,200 pounds (2,818 kg) – up from 6,084 (2,765). On 3500HD models, the rating increases to 7,050 pounds (3,204 kg) on single-rear-wheel models and 9,375 pounds (4,261 kg) on dual-rear-wheel models – the latter representing a nearly 14-percent increase over the previous 8,200-pound (3,727 kg) rating.

Sierra HDs deliver a more refined driving experience, with more capable ride, handling and steering.

The details: Longer wheelbases – ranging from 133.6 inches (3,395 mm) to 167.7 inches (4,259 mm) – and wider front/rear tracks enhance the ride and handling characteristics of the Sierra 2500HD and 3500HD, giving them a greater feeling of smoothness and control. The longer wheelbases and wider tracks are complemented by the new, stiffer frames, new jounce bumpers, shock mounts and hydraulic body mounts to provide a solid, smooth and isolated driving experience. New shocks were specially valved to support the new trucks’ weight ratings, while balancing excellent ride characteristics. Also enhancing the driving experience is a revised steering system designed to support the trucks’ greater front gross axle weight rating. It includes a new, larger steering gear, power steering pumps and linkages. The pumps (different parts for gas and diesel models) deliver greater pressure for reduced steering effort in low-speed and parking maneuvers; they are also quieter. On some models, the new linkages feature a compliant joint added at the pitman attachment to enhance handling.

The new 6.6L Duramax turbo diesel delivers segment-leading torque and up to 63-percent lower NOx emissions; and is B20-capable.

The details: The workhorse Duramax 6.6L turbo diesel V-8 is more powerful and durable for 2011, delivering segment-best horsepower and torque – 397 horsepower (296 kW) at 3,000 rpm and 765 lb.-ft. of torque (1,037 Nm) at 1,600 rpm – lower emissions and B20 biodiesel capability that promotes a domestically produced renewable fuel. The new Duramax 6.6L features:

* NOx emissions reduced at least 63 percent over 2010 models
* Quieter operation
* High-pressure (30,000 psi/2,000 bar) Piezo-actuated fuel system for greater fuel efficiency, improved performance and reduced emissions
* “Smart” exhaust brake feature that enables controlled vehicle slowdown on downhill grades without actuating the brakes
* Selective catalytic reduction after-treatment system using diesel exhaust fluid (DEF) injection to provide the best overall diesel characteristics and performance – with a range of about 5,000 miles (8,000 km) between DEF refills
* Combustion and after-treatment have been optimized to provide about 700 miles (1,125 km) between diesel particulate filter regenerations – a 75-percent improvement over the previous system and a significant contributor to improved fuel efficiency, as the regeneration process requires additional fuel

* B20 biodiesel capability for an alternative fueling option
* Internal revisions that improve durability.

With nearly 1.3 million Duramax 6.6L engines produced since 2000, they have proven exceptionally durable and dependable. The internal elements that helped build its reputation are enhanced for 2011, including:

* Main bearings’ profiles changed to enhance oil film thickness
* Oil pump flow increased for increased pressure at low speeds
* Modified turbocharger oil circuit for increased pressure at the turbo and faster oil delivery
* The connecting rods’ pin ends are modified to provide increased piston support
* New, higher-strength piston design that eliminates bushings to provide lower reciprocating weight
* An EGR cooler bypass reduces high-mileage soot deposits in the cooler and EGR circuit.

COMPETITIVE FACTS: Compared with Ford Super Duty’s urea-based system, Sierra HD’s selective catalytic reduction after-treatment system delivers better overall diesel performance, with a range of about 5,000 miles (8,000 km) between DEF refills. Its optimized combustion and after-treatment process provides about 700 miles (1,125 km) between diesel particulate filter regenerations – a better capability than Ford’s.

New Allison 1000 six-speed automatic transmission works with the Duramax 6.6L to deliver greater fuel economy, quicker acceleration, greater towing capability and exhaust brake system.

The details: The enhanced Allison 1000 is strengthened to handle the higher torque capability of the new 6.6L Duramax engine, while also helping to improve fuel economy and provide seamless assistance with a new exhaust brake system. Greater efficiency is delivered through reduced “spin loss” – meaning, the transmission channels more of the engine’s power to the axles, allowing it to do more with less fuel. The Allison 1000 also features driver shift control with tap up/tap down shifting and a patented elevated idle mode cab warm-up feature. Also, the tow/haul mode reduces shift cycling for better control and improved cooling when towing or hauling heavy loads. The six-speed configuration retains its two overdrive gears for optimal efficiency. Performance with the Duramax/Allison combination is also improved over previous models, with preliminary testing showing 0-60 mph times of less than 9 seconds and quarter-mile times of less than 16 seconds in 2500HD models. That’s about 0.3-second and 0.5-second quicker, respectively, than previous models.

A strengthened Vortec 6.0L/Hydra-Matic 6L90 six-speed powertrain is standard in all models.

The details: The Vortec 6.0L gas V-8 with variable valve timing returns to the new Sierra HDs, along with a strengthened version of the Hydra-Matic 6L90 six-speed automatic transmission. This combination delivers excellent performance and efficiency, with a greater emphasis on low-rpm power. It is enhanced for 2011 with greater idle refinement.

The engine is rated at 360 horsepower (268 kW) at 5,400 rpm and 380 lb.-ft. (515 Nm) at 4,200 rpm in trucks with GVWRs up to 10,000 pounds. It is rated at an estimated 322 horsepower (240 kW) at 4,400 rpm and 380 lb.-ft. of torque (515 Nm) at 4,200 rpm in trucks with GVWRs greater than 10,000 pounds.

The 6L90 is enhanced for greater strength, smoothness and quietness via:

* Adding four attachment bosses to the transfer case adapter (4WD models) for increased strength and smoother, quieter performance

* Increasing the cross section size of the transfer case adapter for greater strength
* Adding a new, stronger output shaft
* Adding a new heat shield and vent hose.

COMPETITIVE FACTS: Ford’s new Super Duty models share the same transmission between their gas and diesel engines. Sierra HDs’ Allison 1000 and Hydra-Matic 6L90 transmission were developed for the specific horsepower, torque and operating range differences that distinguish the diesel and gas engines.

Brake feel and performance is greatly improved.

The details: The standard four-wheel disc system is completely revamped to deliver smoother, more immediate and confident-feeling performance. Four-wheel, four-channel ABS is standard on all single-rear-wheel models and a three-channel system is standard on dual-rear-wheel models. The front and rear rotors are larger in diameter – 14 inches (355 mm) – and width on all models to support their increased capacity, weight ratings and trailering ratings, while the calipers are stiffer and stronger. The hydroboost brake booster calibration is revised for reduced pedal effort, and the travel of the pedal is also revised for a more comfortable, confident feel. Larger wheel hub and bearing assemblies complement the new brake system, and the rear rotors attach to the wheel hubs for easier servicing.

Sierra HD’s ‘smart’ exhaust brake feature provides greater control and reduces brake pad wear.

The details: A new standard feature on Duramax-equipped models is the “smart” exhaust brake. This driver-selectable feature uses the turbine control of the variable geometry turbocharger and the compression of the engine to generate backpressure, slowing the vehicle without applying the brakes. It is integrated with the cruise control feature and varies the braking to account for the grade and vehicle load. The exhaust brake allows for virtually effortless driving and towing, with seamless and quiet operation. It also helps prolong brake life and prevents overheating the brakes on long, downhill grades.

Comprehensive safety features and functional technologies include trailer sway control system and hill start assist.

The details: The 2011 Sierra 2500HD and 3500HD models have a comprehensive roster of safety features and functional technologies that include:

* StabiliTrak electronic stability control system on all single-rear-wheel models
* Larger, four-wheel disc brakes with standard four-wheel ABS
* A new high-strength steel tubular frame cross member that enhances safety and improves crashworthiness
* Seat pelvic/thorax and head curtain side air bags available on 2500HD

* Available rear backup camera
* Segment-exclusive OnStar 9.0
* Trailer sway control system on all single-rear-wheel models
* Hill start assist (standard on single-rear-wheel models)

The trailer sway control system provides an added measure of confidence when towing a trailer. The system senses conditions of trailer sway and intervenes with braking and/or reduced engine power to bring the trailer under control and keep it on its intended path. The system uses electric trailer brakes when a trailer is plugged into the standard wiring harness of the truck and its performance requires no input from the driver. The hill start assist system is automatically engaged when sensors detect the vehicle is on a grade of about 5 percent or greater. It holds the brakes for about 1.5 seconds or until the gas pedal is pressed, preventing rollback – it is particularly effective when towing, giving the driver time to switch from the brake pedal to the gas pedal without rolling.

The GMC Sierra HD lineup is broader than ever.

The details: For 2011, the Sierra heavy-duty lineup expands to include 11 2500HD models and eight single- and dual-rear-wheel 3500HD models – including a new 3500HD Crew Cab with a 6.5-foot cargo box. Other models are offered in WT, SLE and SLT trim levels, while popular features such as the EZ Lift tailgate and rearview camera system are retained.

Sierra HD professional-grade interiors are refined and well-appointed – and ready to work.

The details: From the available remote starting feature to the unimpeded access offered by the 170-degree-opening rear access doors on extended cab models, the 2011 Sierra HD models reflect the professional grade blend of refinement and functionality for which GMC is known. The interiors have excellent attention to detail and are quieter – thanks to the range of the truck’s enhancements. The stronger chassis, quieter Duramax engine and even details like a quieter power steering pump contribute to the Sierra HD delivering exceptional quietness.

Along with quietness, Sierra HD models are designed for work. The interiors feature numerous storage compartments, providing covered access for everything from work gloves to laptops. For those who use their truck as a mobile office, Sierra HDs deliver with available mobile WiFi, USB connectivity, Bluetooth connectivity, XM Satellite Radio and a navigation system. Multiple charge points enable multiple electronic devices to operate simultaneously; and when equipped with the available navigation system, XM NavTraffic offers real-time updates of traffic conditions (in selected areas) that can help plan the most effective route to the job site.

Sierra HDs are ready for the long haul – and the cold.

The details: The 2011 Sierra HDs drive farther without stopping to refuel. A new, 36-gallon (136 L) fuel tank is standard on all models and, with the improved fuel efficiency of the powertrains, enables a cruising range of about 680 miles (1,090 km) with the Duramax 6.6L. Cold-weather customers will appreciate the Duramax 6.6L’s quick, reliable start-up, with a starting time on par with gas engines. Its glow plug cycle time is the segment’s best in all temperatures, taking no more than 3 seconds in temperatures as low as -20 F (-29 C). There’s also a cab heat-up feature that allows the engine to idle faster in low temperatures to warm the interior more quickly.

The 2011 Sierra HD lineup has the best warranty coverage in America.

The details: All 2011 Sierra 2500HD and 3500HD trucks work under the best warranty coverage in America: a five-year/100,000-mile limited powertrain warranty, plus roadside assistance, courtesy transportation and other features that provide assurance that GMC backs its trucks for everything the road offers.

Video: 2011 Audi RS5 Driving Action

Tim Howard — Wed, 10 Mar 2010 18:00:38 +0000

Audi has released a another video of the new 2011 Audi RS5. Unlike the first video, this one shows the RS5 in motion. Better yet, includes some footage of the Ur Quattro, the inspiration behind the RS5.

Click here for more details on the 2011 Audi RS5

Refresher: The 2011 Audi RS5 is powered by a revised version of Audi’s 4.2-liter naturally aspirated V8 found in the previous RS4 and in the current R8 Coupe. It produces 450HP and 317.15 lb-ft of torque, enough to launch the German coupe from 0-62 mph in 4.6 seconds and to a top speed of 155 mph.

New Lamborghini Gallardo LP570-4 Supperleggera

Kwame Owusu — Wed, 10 Mar 2010 17:21:47 +0000

The new 2011 Lamborghini Gallardo LP 570-4 Superleggera made its world debut at this year’s Geneva Motor Show. As the first successor to the original Gallardo Superleggera (“superlight” in Italian), it’s currently the highest-spec model in the Gallardo range. It is powered by a by a direct-injected 5.2-liter V10 that produces 570HP.

Weighing just 2,954 lbs, the 570-4 Superleggera is far lighter than the last superlight Gallardo’s 3,153 lbs. This is made possible by the abundant usage of carbon fiber materials. Other performance features include 19-inch forged aluminum wheels wearing Pirelli P Zero Corsa rubber, optional carbon ceramic disc brakes, permanent all-wheel drive and a six-speed e-gear transmission.

All in all, less weight and more power means that the LP570-4 Supperleggera can run from 0 to 62 mph in just 3.4 seconds and reach a top speed of 202 mph. More details can be found in Lamborghini’s press release.

PRESS RELEASE:

Lamborghini Gallardo LP 570-4 Superleggera

Even more dynamic, lighter, more powerful and stunning – the Lamborghini Gallardo LP 570-4 Superleggera is the new top model in the Gallardo line- up. Its evocative “superlight” badge refers to a driving machine of true sporting character and describes a high-performance and lean automotive athlete. The Superleggera makes its entrance to continue the success of its predecessor, launched in 2007, of which Lamborghini produced and sold no less than 618 in just one year.

Compared with the already lean Gallardo LP 560-4, the weight of the Gallardo Superleggera has been trimmed by 70 kilograms (154 lb). The super sportscar from Sant’Agata Bolognese boasts a dry weight of no more than 1340 kilograms (2954 lb) – the lightest road-going model in Lamborghini’s range, and a new arrival in one of the most exclusive market niche segments.

One key factor is the exterior and interior components made from carbon- fiber. Carbon-fiber is ideal for the manufacture of sportscars as its use allows for weight reduction and improved mechanical features. The car’s performance is thus enhanced thanks to a better weight-to-power ratio and reduced total mass, which means that CO2 emissions are also lower. Lamborghini has been at the forefront in this material’s application for many years, and now the brand is extending its leadership even further.

The V10 power unit with 5.2 liters (317,6 cu in) of displacement generates 419 kW (570 CV*) in the Gallardo Superleggera. This puts the weight-to- power ratio of the new top model at only 2.35 kilograms (5.18 lb) per CV and guarantees breathtaking performance. The Gallardo LP 570-4 Superleggera handles the dash from zero to 100 km/h (0-62 mph) in 3.4 seconds and flies past the 200 km/h (124 mph) mark only 10.2 seconds later, ultimately reaching 325 km/h (202 mph). The engine with “Iniezione Diretta Stratificata” gasoline direct injection also boasts an impressive degree of efficiency. Its fuel consumption and CO2 emissions have been reduced by 20,5 percent compared to the previous model.

The Gallardo Superleggera is an uncompromising driving machine. Its running gear, with its mighty braking system, has a dedicated and exceptionally precise set-up, while its 19-inch wheels, Pirelli P Zero Corsa, clad in Pirelli sports rubber, are extremely light. The Lamborghini Gallardo LP 570-4 Superleggera brings a whole new meaning to the term “super sportscar”.

Design and aerodynamics The beauty of power

The elegance of every Lamborghini rests on both its extreme power and precise functionality. The Gallardo LP 570-4 Superleggera’s bodyshell is sculptured and completely free from stylistic additions. Dimensions define the contours of a dynamic wedge – 4.39 meters (172,7 in) long, 1.90 meters (74,8 in) wide, but only 1.17 meters (45,9 in) high.

Exterior modifications are all directed at increasing aerodynamic effects. Working closely with wind tunnel experts, the designers from Lamborghini’s Centro Stile remodeled the front bumper – three-dimensional, deeply recessed elements form trapezoidal frames for the large air intakes. Together with the V-shaped, sharply defined nose and the LED daytime running lights, the black elements give the front end a razor-sharp look, reminiscent of Lamborghini’s top model. The new design increases the supply of cooling air and improves the downforce on the front axle.

The modifications to the fully-covered underbody, which include new sill elements and a redesigned diffuser incorporating four large tailpipes, help to achieve better aerodynamic results. The Gallardo Superleggera sports a small rear spoiler as standard. A big rear spoiler is available as an option.

The bodyshell Intelligent lightweight engineering

The model on which the Gallardo LP 570-4 Superleggera is based, the Gallardo LP 560-4, is already a prime example of Lamborghini’s lightweight engineering philosophy, with its dry weight of 1410 kilograms (3108.5 lb). Its bodyshell is made from aluminum, with moulded node elements and extruded parts forming an extremely stiff framework into which the aluminum panels are integrated. The spaceframe structure is impact-resistant and forms the basis for the super sportscar’s precise handling.

Against this background, the task of reducing the weight by a further 70 kilograms (154 lb) presented a huge challenge to Lamborghini engineers – the target figure, a weight-to-power ratio of 2.35 kilograms (5.18 lb) per CV, sets a new best among the competition. Lamborghini engineers handled the task as they usually do – with hi-tech competence and aesthetic flair.

The rear windshield and side windows are made from robust and resistant polycarbonate. The engine cover also includes a polycarbonate window, beneath which the V10 engine is displayed like a technical work of art. The long cover section runs from the roof to the rear of the vehicle and is made from carbon-fiber. Engineers also selected carbon-fiber for the rear spoiler, sills, diffuser, parts of the underbody paneling and the fine exterior mirror casings.

With its minimal weight and extremely high rigidity, carbon-fiber is the ideal material for a super sportscar. As far back as the 1980s, Lamborghini was already gathering experience in this field with the Countach. Today, some parts of the Murciélago’s structure are made from carbon-fiber. In order to secure this leading position even further, the brand from Sant’Agata Bolognese established a center of excellence for carbon-fiber materials, where specialists are developing components, working with efficient manufacturing technologies.

Lamborghini’s carbon-fiber strategy is further proven by its foundation of the “Automobili Lamborghini Advanced Composite Structures Laboratory” (ACSL) at the University of Washington in Seattle, USA. Lamborghini provides support to the facility and its long-term, co-operative research work in the fields of aeronautics and astronautics, together with the composite materials’ application within the automotive sector. Alongside the University of Washington, aircraft company Boeing is also among Lamborghini’s partners.

The aircraft manufacturer commands enormous expertise in the field of composite materials. With the new Type 787 Dreamliner, Boeing has developed the world’s first commercial aircraft built entirely from carbon- fibre. Thanks to its superior characteristics, it consumes around 20 percent less fuel than a conventional aeroplane.

The interior and the use of carbon-fiber

Altogether, carbon-fiber components make up 40 (88 lb) of the 70 kilograms (154 lb) saved on the Gallardo Superleggera. In the interior, too, engineers aimed to reduce weight as much as possible. The center tunnel cover, the door panels and the surround of the e-gear automated manual transmission lever are made from carbon-fiber. The high-end material is also used for the sports seats’ shells. They make a significant contribution to the overall weight reduction.

Just like the rest of the cockpit, the sports seats are clad in lightweight Alcantara instead of leather. At Lamborghini, weight reduction is in no way synonymous with sacrifice – the Gallardo LP 570-4 Superleggera is still equipped with air conditioning and electric powered windows as standard.

Lamborghini has built on this strength – the interior is crafted with passionate attention to the tiniest detail; high quality materials indulge both visually and sensually.

The interior, including roof and mats, retains the Lamborghini Gallardo’s black finish. As a contrasting color for elements such as seat trims and stitching, customers can choose among green, yellow, orange and two shades of gray. They match exterior paint finishes in Verde Ithaca, Giallo Midas, Arancio Borealis, Grigio Telesto, Nero Noctis and Bianco Monocerus.
The engine 10.2 seconds from zero to 200 km/h

In the Gallardo LP 570-4 Superleggera, LP stands for “longitudinale posteriore” and refers to the orientation of the V10 engine – which is mounted longitudinally behind the driver, just like every Lamborghini engine. The number 570 refers to the maximum power output in CV, which equates to 419 kW and is available at 8,000 rpm. Equally impressive is the pulling power – the torque curve peaks at 540 Nm (398,3 ft lbs) at 6,500 rpm. The increase of 7 kW (10 CV) is the result of the new dedicated engine management strategy.

The V10 has a displacement of 5204 cm3 and achieves a specific output of 80.5 kW (109.6 CV) per liter. Special features on this long-stroke engine with an aluminum crankcase include dry sump lubrication and a cylinder angle of 90 degrees. Both solutions lower the center of gravity, thus improving the handling dynamics. To ensure an ideal combustion chamber fill, the engine has an adjustable intake manifold and continuous control of the chain-driven camshafts.

The crankshaft is conceived as a dual-plane crank – the connecting rods of opposing pistons share one bearing. This configuration delivers alternating ignition intervals of 54 and 90 degrees; a unique sequence that is the reason for the compelling, racing car-like sound of the V10. As the revs rise, resounding bass notes are overlaid with razor sharp harmonics.

The powerful V10, combined with the model’s weight reduction, gives the Gallardo Superleggera LP 570-4 breathtaking performance. The car accelerates zero to 100 km/h (0-62 mph) in just 3,4 seconds, 0 to 200 km/h (0-124 mph) in 10,2 seconds – then continues relentlessly to its top speed of 325 km/h (202 mph).

The Gallardo Superleggera is also considerably more efficient – compared with its predecessor, its fuel consumption in the EU driving cycle is reduced by 3,5 liters per 100 kilometer (0,9 gal), or 20,5 percent, to 13,5 liters/100 km (16 mpg). This improvement is partly due to the “Iniezione Diretta Stratificata” gasoline direct injection, which injects fuel into the combustion chambers at pressures of up to 100 bar. The tumbling mix cools the combustion chambers, which enables a very high compression ratio of 12.5:1 which, in turn, increases efficiency.

Power transmission Traction without compromise

The Gallardo LP 570-4 Superleggera comes with the e-gear transmission operated via steering wheel paddles, as standard. The automated system with electronic management shifts through its six gears extremely smoothly and far more quickly than could be achieved by human reflexes.

The e-gear control unit has three operating modes, two of which available in automatic. The “Thrust mode” delivers maximum off-the-line performance and is programmed to manage starting revs of around 5000 rpm with minimal wheel slip.

Every single kilometer in the new Superleggera is utterly thrilling – not least because of the relentless traction in practically every situation. This is largely attributable to the four driven wheels, as indicated by the number 4 in the model name.
The permanent all-wheel drive integrates a central viscous coupling and a 45 percent limited slip differential on the rear axle. In normal circumstances, the power delivered by the V10 is channeled with a ratio of 30:70 to the front and rear axles. The weight distribution of the superlight Gallardo is 43/57 percent front/rear.

In 1993, the Diablo VT was the first Italian super sportscar with an all-wheel drive set-up, and Lamborghini has been steadily consolidating its leadership ever since. In fact, thanks to the car’s superior traction, Lamborghini drivers can accelerate earlier out of a bend than drivers of rear-wheel drive cars.

The running gear Even firmer, even more precise

The new Gallardo Superleggera is a highly-concentrated driving machine – it thrills with breathtaking cornering speeds and fast, immediate feedback. Its handling is always precise, stable and predictable.

The running gear layout is derived directly from Lamborghini’s motorsport experience. The suspension is aluminum double wishbones. The precise rack and pinion steering keeps the driver very closely connected with the road. The shock absorbers are extremely firm, and the anti-roll bars and suspension mounts have been further reinforced: these features enable the running gear to reach its full dynamic potential. No other model in the Gallardo range is as close to a race car as this one. The development of the Superleggera was heavily influenced by experiences gained from the world’s fastest single-brand race series, the Lamborghini Blancpain Super Trofeo.

Another special feature of the Gallardo Superleggera is the wheels. The 19- inch units are aluminum forged and are therefore extremely lightweight – saving 13 kilograms (28.6 lb). The wheel bolts are made from titanium and are also incredibly light and rigid. The tires are 235/35 ZR19 at the front and 295/30 ZR19 at the rear and come from the Pirelli P Zero Corsa series. Developed specifically for the new top model in the Gallardo range, they are closely related to pure race rubber.

Behind the huge wheels are brakes that serve to deliver uncompromising stopping power and are managed by the standard-fit ESP stability control system. The front wheels are served by aluminum eight-piston calipers, with four-piston units at the rear. The ventilated brake discs have a diameter of 365 and 356 millimeters (ø 14.37 x 1.34 in and 14.02 x 1.26 in) respectively. As an optional extra, Lamborghini can fit extremely fade- resistant and lightweight discs made from carbon-fiber ceramic with six pistons at the front. The front ceramic discs have a diameter of 380 millimeters (ø 15 x 1.5 in).

Equipment Hi-tech for road and track

Alongside its specialized carbon-fiber lightweight components, the Lamborghini Gallardo LP 570-4 Superleggera is delivered ex-works with an array of other high-end features. Highlights include the e-gear transmission – a manual gearbox is also available at no additional cost – the dedicated set-up, the Pirelli sports tires and the sports seats. Alcantara upholstery and a hand-stitched steering wheel also set the interior ambiance.

The range of special equipment is particularly sporty. It includes carbon- fiber ceramic brake discs, four-point seat belts, fire extinguisher and a steel roll cage. Visual impact can be further increased by a rear spoiler and the engine bay for the engine compartment – both from carbon-fiber – as well as colored brake calipers.

For the interior, Lamborghini offers special floor mats and leather steering wheels, a storage package and an alarm system. An additional carbon-fiber package includes center console and instrument panel trim, the parking brake handle, parts of the steering wheel and the door handles. A LED light package illuminates the engine compartment, the interior, and the entry area.

Additional features of special equipment increase comfort, such as the multimedia navigation system, the lifting system which raises the front of the car to enable driving over obstacles, a remote control for opening garage doors and a rear view camera mounted beneath the rear spoiler. Customers who want to personalize their Gallardo LP 570-4 Superleggera, can use Lamborghini’s wide-ranging options of the “Ad Personam” individualization program.

BRING IT ON – 11 WAYS THE NEW 2011 CHEVROLET SILVERADO HEAVY-DUTY TRUCKS PROVE THEY’RE READY FOR ANY JOB OR COMPETITOR

CHICAGO – On a recent validation drive of the new, 2011 Chevrolet Silverado heavy-duty trucks, engineer Brent Deep towed a 20,000-pound (9,072 kg) trailer for 245 miles (400 km) along I-70 between Denver and Grand Junction, Colo. – and he barely touched the brakes the entire way.

Deep relied on the Silverado’s new, smart exhaust brake system to slow the truck/trailer combination on descents, helping prove the new system is suitable for the most demanding conditions. It was a drive across the heart of the Rocky Mountains and some of the interstate system’s steepest grades, with altitudes ranging from Denver’s approximately 5,000 feet (1,525 m) to more than 11,100 feet (3,400 m) at the Eisenhower Tunnel.

“It takes some courage to leave your foot off the brake, but the Silverado’s Duramax engine and Allison transmission perform the task with smoothness and confidence that really impresses,” said Deep. “Better still, the exhaust brake system can help extend brake pad life and help avoid overheating the brakes on long descents.”

The exhaust brake system feature is just one of the elements that makes the new 2011 Silverado 2500HD and 3500HD models the most capable in the industry. They go on sale this summer.

“We sought the input of our customers during the development of the 2011 Silverado HD to deliver a truck that meets or exceeds their every need,” said Jim Campbell, Chevrolet general manager. “It offers greater strength and capability – including class-leading fuel economy, trailering and payload ratings – and has more power, accelerates quicker and has lower emissions. That sounds like the very definition of no compromises.”

The Silverado heavy-duty lineup is broader than ever, with 11 2500HD models and eight single- and dual-rear-wheel 3500HD models – including a new 3500HD Crew Cab with a 6.5-foot cargo box. WT, LT and LTZ trim levels are offered, and popular features such as the EZ Lift tailgate and rearview camera system return. All models bring greater capability, improved ride and handling and a greater feeling of driver control. Depending on the model:

* Segment-best fifth-wheel towing capacity of 20,000 pounds (9,072 kg)
* Segment-best conventional towing capacity increases up to 23 percent, with a maximum of 16,000 pounds (7,272 kg)
* Segment-best payload capability of 6,335 pounds (2,873 kg) on a complete vehicle
* Segment-best Gross Combined Weight Rating increases to 27,500 pounds (12,500 kg)
* Gross Vehicle Weight Ratings increases up to 17 percent to 13,000 pounds (5,909 kg)
* Front Axle Weight Rating increases by up to 25 percent to 6,000 pounds (2,721 kg)
* Snow plow capability is now enabled for all 4WD cab configurations

There are also enhanced powertrains, including a new Duramax 6.6L diesel/Allison 1000 six-speed transmission that offers the exhaust brake system, new front and rear suspensions, an improved brake system, hill start assist, trailer sway control system and more.

“Along with all their heavy-duty equipment, these trucks are designed to be stylish and refined, inside and out,” said Campbell. “We paid close attention to all the details, giving them a distinctive, muscular appearance on the exterior and a well-appointed interior with the comfort, convenience and safety features customers appreciate.”

Outside, the 2011 Silverado 2500HD and 3500HD models are distinguished by a power dome-style hood with a new, louvered design, as well as a new grille and full-width chrome steel front bumper. A new lineup of 17-, 18- and 20-inch wheel/tire combinations is featured, too (20-inch polished forged aluminum wheels are available on 2500HD).

Designers and engineers left almost no bolt unturned during the comprehensive redesign of the trucks. Here are 11 key elements that demonstrate the 2011 Silverado 2500HD and 3500HD are ready for any job and any competitor:

1. New frames

In the quest to comprehensively redesign the Silverado HD chassis to improve durability and ride, while also supporting increased capability, engineers developed 11 all-new, fully boxed frame assemblies. The frames have increased cross sections and use more high-strength steel for greater durability, higher towing capacity and improved ride and handling; the front sections are hydroformed.

The bending and beaming stiffness of the frames is increased 92 percent and 20 percent, respectively, with the fully boxed sections enhancing torsional stiffness by a factor of five. Also, larger engine and transmission mounts, coupled with a 125-percent-stiffer front frame structure, provide greater vibration control, while hydraulic body mounts are incorporated under the cab section on extended and crew cab models for a more isolated feel inside.

Engineers addressed common customer and aftermarket uses when designing the new frames, including adding access holes to the rear frame section to enable easier installation of fifth-wheel/gooseneck-style hitches. Also, the frame-mounted hitch for conventional trailering is stronger, with a box-tube design. It supports up to 16,000 pounds (7,257 kg).

2. New and strong independent front suspension

A completely redesigned independent front suspension system offers up to a 25-percent greater front axle weight rating – up to 6,000 pounds (2,721 kg) front gross axle weight rating (FGAWR) – enabling a snow plow to be used on all 4WD cab configurations with the available snow plow prep package, while also supporting improved ride and handling characteristics.

Silverado’s signature short-long arm/torsion bar front suspension design is retained, but now features new, forged steel upper control arms that are stronger and lighter than their predecessors. The new lower control arms are made of precision-machined cast iron to handle the greater loads. Five different torsion bar rates support five different front gross axle weight ratings (a single torsion bar was previously used for all models). This helps stabilize the range of trim heights of various models under load, while enhancing appearance, handling, durability, tire wear and alignment. The trim height is adjusted on each bar via a single bolt, easily allowing the height to be changed to account for the weight of a snow plow or other accessories.

The Silverado HD front suspension now uses a pair of urethane jounce bumpers on each side, instead of one, for improved load management; and there’s a new upper shock mount attachment design that’s positively connected to the frame with two fasteners. This design eliminates squeaks and clunks, while supporting higher load capability and increased durability.

Compared to competitors’ beam-axle front suspension, the Silverado’s independent front suspension provides a better ride, more accurate trim height control (with fewer parts) and greater flexibility to adjust the alignment for weight and tire sensitivity.

3. New asymmetrical leaf-spring rear suspension

Commensurate with the Silverado HD’s greater strength and capability is a rear suspension designed to support greater loads. It features a new, larger asymmetrical leaf-spring design that also contributes to improved ride and handling characteristics.

The asymmetrical design is derived from unequal front and rear spring half lengths, which minimize axle hop and enhance traction control efficiency. 2500HD models feature a two-stage leaf-spring design, while 3500HD models have a three-stage design. All models feature 3-inch-wide (76 mm) leaf springs that are 20-percent wider than previous models.

The larger leaf-spring design supports increased rear gross axle weight ratings across the board. On the 2500HD models, the rating is 6,200 pounds (2,818 kg) – up from 6,084 (2,765). On 3500HD models, the rating increases to 7,050 pounds (3,204 kg) on single-rear-wheel models and 9,375 pounds (4,261 kg) on dual-rear-wheel models – the latter representing a nearly 14-percent increase over the previous 8,200-pound (3,727 kg) rating.

4. Segment-leading towing and payload capability

Stronger frames, suspension systems with greater weight ratings and enhanced powertrain systems contribute to the Silverado HD’s class-leading towing and payload capability. The specifications charts included below outline capacities for each model and/or configuration, but here are the key facts:

* The maximum conventional (ball hitch) towing rating increases to 16,000 pounds (7,257 kg)
* A Silverado 3500HD crew cab/long box can tow up to 20,000 pounds (9,091 kg) with a fifth-wheel hitch. The 2010 Ram 3500 has a maximum rating of 17,600 pounds (8,000 kg) and the 2010 Ford F-350 is rated at a maximum of 18,800 pounds (8,545 kg). It should be noted that while Ford claimed segment-leading trailering and payload during its recent announcement of the 2011 Super Duty models, no towing ratings were issued
* The maximum payload (3500HD) is 6,335 pounds (2,873 kg) – that’s nearly 11 percent greater than the 2010 Ford F-350’s 5,730-pound (2,604 kg) rating and about 24 percent more than the 2010 Ram 3500’s 5,130-pound (2,331 kg) ratings. Again, while claiming segment-leading payload for the 2011 Super Duty models, Ford did not announce the ratings

5. New 6.6L Duramax diesel and Allison 1000 six-speed combination

Helping the new 2011 Silverado HD trucks deliver their best-in-class capabilities is a new version of the workhorse Duramax 6.6L diesel and Allison 1000 six-speed automatic transmission powertrain combination. The Duramax 6.6L is more powerful and durable and the Allison 1000 is stronger and helps enable new features, including the exhaust brake system. Together, this improved version of a proven combination is also expected to deliver segment-best fuel economy.

The Duramax 6.6L’s new and improved features include:

* Horsepower and torque expected to top previous model (testing is ongoing – check media.gm.com for updates)
* NOx emissions reduced at least 63 percent over 2010 models
* Quieter operation
* High-pressure (30,000 psi/2,000 bar) Piezo-actuated fuel system for greater fuel efficiency, improved performance and reduced emissions
* Exhaust brake system that enables controlled vehicle slowdown on downhill grades without actuating the brakes
* Selective catalytic reduction after-treatment system using diesel exhaust fluid (DEF) injection to provide the best overall diesel characteristics and performance – with a range of about 5,000 miles (8,000 km) between DEF refills
* Combustion and after-treatment have been optimized to provide about 700 miles (1,125 km) between diesel particulate filter regenerations – a 75-percent improvement over the previous system and significant contributor to improved fuel efficiency, as the regeneration process requires additional fuel
* B20 biodiesel capability for an alternative fueling option
* Internal revisions that improve durability

With nearly 1.3 million Duramax 6.6L engines produced since 2000, they have proven exceptionally durable and dependable. The internal elements that helped build its reputation are enhanced for 2011, including:

* Main bearings’ profiles changed to enhance oil film thickness
* Oil pump flow increased for increased pressure at low speeds
* The turbocharger’s oil circuit is changed to provide increased pressure at the turbo and faster oil delivery
* The connecting rods’ pin ends are modified to provide increased piston support
* New, higher-strength piston design that eliminates bushings to provide lower reciprocating weight
* An EGR cooler bypass reduces high-mileage soot deposits in the cooler and EGR circuit

The enhanced Allison 1000 for 2011 is strengthened to handle the higher torque capability of the new 6.6L Duramax engine, while also helping improve fuel economy and provide seamless assistance with a new exhaust brake system. Greater efficiency is delivered through reduced “spin loss” – meaning, the transmission channels more of the engine’s power to the axles, allowing it to do more with less fuel.

The Allison 1000 also features driver shift control with tap up/tap down shifting and a patented elevated idle mode cab warm-up feature. Also, the tow/haul mode reduces shift cycling for better control and improved cooling when towing or hauling heavy loads. The six-speed configuration retains its two overdrive gears for optimal efficiency.

Performance with the Duramax/Allison combination is also improved over previous models, with preliminary testing showing 0-60 mph times of less than 9 seconds and quarter-mile times of less than 16 seconds in 2500HD models. That’s about 0.3-second and 0.5-second quicker, respectively, than previous models.

6. Strengthened Vortec 6.0L/Hydra-Matic 6L90 six-speed powertrain

The venerable Vortec 6.0L gas V-8 with variable valve timing returns to the new heavy-duty trucks, along with a strengthened version of the Hydra-Matic 6L90 six-speed automatic transmission. This combination delivers excellent performance and efficiency, with a greater emphasis on low-rpm power.

A new camshaft profile in the Vortec 6.0L helps the engine produce more torque lower in the rpm band, for improved launch feel and a greater feeling of overall performance at higher altitudes and when towing a trailer.

The 6L90 is enhanced for greater strength, smoothness and quietness via:

* Adding four attachment bosses to the transfer case adapter (4WD models) for increased strength and smoother, quieter performance
* Increasing the cross section size of the transfer case adapter for greater strength
* Adding a new, stronger output shaft
* Adding a new heat shield and vent hose

7. Exhaust brake system

A new feature on Duramax-equipped models is an exhaust brake system. This driver-selectable feature uses the turbine control of the variable geometry turbocharger and the compression of the engine to generate backpressure, slowing the vehicle without applying the brakes. It is a smart system integrated with the cruise control feature and varies the braking to account for the grade and vehicle load.

The exhaust brake system allows for virtually effortless driving and towing, with seamless and quiet operation. It also helps prolong brake life and prevents overheating the brakes on long, downhill grades.

8. Large brakes

Brake feel and performance is greatly improved with the 2011 Silverado HD trucks. The standard four-wheel disc system is completely revamped to deliver smoother, more immediate and confident-feeling performance. Four-wheel, four-channel ABS is standard on all single-rear-wheel models and a three-channel system is standard on dual-rear-wheel models.

The front and rear rotors are larger in diameter – 14 inches (355 mm) – and width on all models to support their increased capacity, weight ratings and trailering ratings, while the calipers are stiffer and stronger. The hydroboost brake booster calibration is revised for reduced pedal effort and the travel of the pedal is also revised for a more comfortable, confident feel.

Larger wheel hub and bearing assemblies complement the new brake system and the rear rotors attach to the wheel hubs for easier servicing.

9. Refined and capable ride, handling and steering

Longer wheelbases – ranging from 133.6 inches (3,395 mm) to 167.7 inches (4,259 mm) – and wider front/rear tracks enhance the ride and handling characteristics of the Silverado 2500HD and 3500HD, giving them a greater feeling of smoothness and control.

The longer wheelbases and wider tracks are complemented by the new, stiffer frames, new jounce bumpers, shock mounts and hydraulic body mounts to provide a solid, smooth and isolated driving experience. New shocks were specially valved to support the new trucks’ weight ratings, while balancing excellent ride characteristics.

Also enhancing the driving experience is a revised steering system designed to support the trucks’ greater front gross axle weight rating. It includes a new, larger steering gear, power steering pumps and linkages. The pumps (different parts for gas and diesel models) deliver greater pressure for reduced steering effort in low-speed and parking maneuvers; they are also quieter. On some models, the new linkages feature a compliant joint added at the pitman attachment to enhance handling.

10. Comprehensive safety and functional technology

The 2011 Silverado 2500HD and 3500HD models have a comprehensive roster of safety features and functional technologies that include:

* StabiliTrak electronic stability control system on all single-rear-wheel models
* Larger, four-wheel disc brakes with standard four-wheel ABS
* A new high-strength steel tubular frame cross member that enhances safety and improves crashworthiness
* Seat pelvic/thorax and head curtain side air bags available on 2500HD
* Available rear backup camera
* Segment-exclusive OnStar 9.0
* Trailer sway control system on all single-rear-wheel models
* Hill start assist (standard on single-rear-wheel models)

Trailer sway control system provides an added measure of confidence when towing a trailer. The system senses conditions of trailer sway and intervenes with braking and/or reduced engine power to bring the trailer under control and keep it on its intended path. The system will use electric trailer brakes when a trailer is plugged into the standard wiring harness of the truck and its performance requires no input from the driver.

The hill start assist system is automatically engaged when sensors detect the vehicle is on grade of about 5 percent or greater. It holds the brakes for about 1.5 seconds or until the gas pedal is pressed, preventing rollback – it is particularly effective when towing, giving the driver time to switch from the brake pedal to the gas pedal without rolling.

11. Lives bigger, drives better, works harder

From the available remote starting feature to the unimpeded access offered by the 170-degree-opening rear access doors on extended cab models, the 2011 Silverado HD models live bigger, drive better and work harder. The interiors are refined, with improved quietness and attention to detail, but designed for working. Numerous storage compartments provide covered access for everything from work gloves to laptops.

Indeed, for many owners the Silverado HDs are mobile workspaces, offering mobile WiFi, USB connectivity, Bluetooth connectivity, XM Satellite Radio and a navigation system. Multiple charge points enable multiple electronic devices to operate simultaneously; and when equipped with the available navigation system, XM NavTraffic offers real-time updates of traffic conditions (in selected areas) that can help plan the most effective route to the job site.

Cold-weather customers will appreciate the Duramax 6.6L’s quick, reliable start-up, with a starting time on par with gas engines. Its glow plug cycle time is the segment’s best in all temperatures, taking no more than 3 seconds in temperatures as low as -20 F (-29 C). There’s also a cab heat-up feature that allows the engine to idle faster in low temperatures to warm up the interior faster.

And when you’re on the road, the Silverado HDs take you farther without stopping. A new, 36-gallon (136 L) fuel tank is standard on all models and, with the improved fuel efficiency of the powertrains, enables a cruising range of up about 680 miles (1,090 km) with the Duramax 6.6L. That’s the equivalent of a trip from Houston to Oklahoma City and back to Dallas on a single tank.

Finally, all 2011 Silverado 2500HD and 3500HD trucks work under the best warranty coverage in America – five-year/100,000-mile limited powertrain warranty, plus roadside assistance, courtesy transportation and other features that provide assurance that Chevrolet backs its trucks confidently.

Video: Runaway Toyota Prius vs Police

Tim Howard — Wed, 10 Mar 2010 15:30:13 +0000

In yet another slap to Toyota`s face, a California Highway Patrol officer helped stop a runaway Toyota Prius on a San Diego County freeway. With its accelerator stuck, the Prius reached 94 mph, but luckily the officer was able to bring the car safely to a halt.

To make matters worse, James Sikes, the 61 year-old man stuck in the Prius, said he took his Prius to a dealership for repairs after receiving a recall notice; however, he was turned away.

“I gave them my recall notice and they handed it back and said I’m not on the recall list,” Sikes said.

Sikes called 911 after accelerating in an attempt to pass another vehicle on Interstate 8 when he realized that he could not control the Prius.

“I pushed the gas pedal to pass a car and it did something kind of funny … it jumped and it just stuck there,” the 61-year-old driver said.

“As it was going, I was trying the brakes … it wasn’t stopping, it wasn’t doing anything and it just kept speeding up,” Sikes said, adding he could smell the brakes burning he was pressing the pedal so hard.

Eventually an officer pulled alongside the Prius and told Sikes to push the brake pedal to the floor and pull the emergency brake. Once the car slowed to 50 mph, SIkes turned off the engine and coasted with the officer`s car in front of the Prius as a precautionary block. You can watch the news report below…

Video: 2011 Audi RS5 Exterior and Interior

Tim Howard — Tue, 09 Mar 2010 18:30:47 +0000

There would be no justice if all we had for you were a bunch of pictures and words on the 2011 Audi R5. Well, we here at AutoTribute are all for justice, so we’ve taken the liberty to post an all new video of the latest RS5. The video gives a nice detailed look of the RS5’s exterior and interior. Enjoy!

Click here for more details on the 2011 Audi RS5

Refresher: The 2011 Audi RS5 is powered by a revised version of Audi’s 4.2-liter naturally aspirated V8 found in the previous RS4 and in the current R8 Coupe. It produces 450HP and 317.15 lb-ft of torque. That’s enough to launch thee RS5 from 0-62 mph in 4.6 seconds and to an electronically-limited top speed of 155 mph.
