BMW M550d

Diesel-powered BMWs are very popular in Europe, and so is BMW’s M division. However, for one reason or another, the two have been mutually-exclusive for-like-ever. Until now, that is. BMW’s M division has finally revealed three diesel-powered models, the M550d, X5 M50d and X6 M50d. Let’s take a look at the M550d xDrive Sedan and Touring.

The BMW M550d, like the other two models, is powered by a new 3.0 liter 6-cylinder in-line diesel engine with M Performance TwinPower Turbo technology that uses three turbochargers. The engine produces 381 horsepower at 4,000 rpm and a maximum torque of 546 lb-ft between 2,000 and 3,000 rpm. Equipped with an eight-speed automatic gearbox and standard xDrive AWD, the M550d sedan can sprint to 60 miles per hour (96.5 km/h) in 4.6 seconds, which is just four tenths of a second slower than the all-new M5′s time. The M550d Touring does the deed in 4.9 seconds.

As with the other two models, the M550d sedan and touring benefit from modifications to the chassis components. These include M-specific tuning of the suspension, bodyshell mounting, engine and transmission mounting, springs and dampers, all standard and optional chassis control systems, and the Servotronic mapping for the hydraulic steering. Exclusive on the M550d models are 19-inch alloy wheels in double-spoke design. 20-inch M light-alloy wheels in Ferric Grey are optional.

Exterior updates on the M550d include exterior mirrors and air intake bars with striking Ferric Grey metallic paintwork; trapezoidal exhaust tailpipes; BMW Individual High-gloss Shadow Line; model lettering on the door sills and boot lid; engine cover with “M Performance” badge.

Interior updates include exclusive Alcantara/Cloth in Grey Shadow with contrast stitching and embossed M logo; gearshift lever with M logo; M leather steering wheel with gearshift paddles; BMW Individual roof liner in Anthracite; and Aluminium Hexagon.

The M550d sedan and Touring will be available in Europe this April and will make their official debut at the 2012 Geneva Motor Show. North America buyers are out of luck — no M550d for them.
