Although BMW has only revealed the i3 and i8 concept cars, the German automaker’s new i-Series sub-brand will be comprehensive. New details on the future i lineup indicate that the company is considering two additional models, an i4 and an i5.
The i4 would reportedly be a two-seater based on the i3, while the i5 is reported to be a mid-size four-door sedan with a coupe-like profile, likely sharing the same powertrain as the i8. There are also reports that the i8 will get a convertible version, while the i3 will get an extended-length version. Stay tuned form details.
