BMW has introduced the all new 2015 BMW M4 convertible model which is all set to reach US dealerships to join the M4 Coupe late this summer. The M4 is a replacement to the M3 and from the day BMW announced the same, we were expecting a droptop version of the same. Perhaps the most important change on the M4 Convertible model is the new engine. The M4 Convertible equips the same BMW M TwinPower Turbo 3.0 liter inline-6 cylinder heart that powers the M3 Sedan and M4 Coupe. Compared to the previous generation which was powered by a V8 engine, the M4 Convertible’s inline-six puts out an identical 425 hp and a 40 percent increased peak torque of 406 lb-ft.

The high revving engine helps the M4 Convertible sprint from 0 to 60 mph in just 4.4 seconds on the manual version while the automatic variant takes 4.2 seconds.
