The BMW M3 (F80) has been the subject of an acceleration test on an unrestricted section of the autobahn in Germany.
Featured in the video is a brand new M3 equipped with the optional 7-speed M DCT gearbox which according to BMW's tests allows the high-performance sedan sprint to 62 mph (100 km/h) from a standstill in 4.1 seconds. However, the attached footage shows the 2014 M3 Sedan is actually 0.2 seconds quicker in the sprint.
The acceleration test continues with the 124 mph (200 km/h) mark reached in 12.6 seconds with very little effort while the 0-155 mph (0-250 km/h) journey takes 19.8 seconds. As you can see from the clip, the M3 F80 goes beyond the limited 155 mph mark of the standard car which means it's equipped with the optional M Driver's Package granting an electronically-capped 174 mph (280 km/h) top speed but in this video the driver doesn't go beyond 168 mph (270 km/h).
It's all possible thanks to a six-cylinder 3.0-liter TwinPower Turbo engine outputting 431 HP (317 kW) and 406 lb-ft (550 Nm) of torque delivered to the rear wheels. The engine can also work with a standard six-speed manual gearbox but the 0-62 mph sprint time will decrease by 0.2 seconds to 4.3s according to BMW's estimations.
