F30 BMW M3 sedan, F32 M4 coupe sport 3L twin-turbo straight-6

BMW has officially revealed its new generation M3 sedan and M4 coupe twins, which is powered by a new twin-turbo 3-litre straight-six that revs to 7,600rpm.


Under the bulging hood of the new F32 M4 coupe (above) and F30 M3 sedan (below) is a 3-litre twin-turbo straight 6-cylinder engine churning out 321kW of power and 550Nm of torque for the rear wheels via an active limited-slip diff (sorry, Active M Differential). When equipped with the optional 7-speed dual-clutch transmission the new M3/M4 pair can race from 0 to 100km/h in 4.1 seconds.

Weight is down around 80kg from the previous generation M3 coupe and sedan thanks to weight loss in the regular 3-Series and 4-Series range, as well as the use of aluminium and carbon fibre components. The new M3/M4 pair feature a carbon fibre roof and electric power steering as standard.

The new car rides on 18-inch alloys as standard, although larger 19-inch wheels can be optioned. Tech available on the M3/M4 includes LED headlights with automatic high beam; adaptive cruise control that works in stop/start traffic; head-up display with tachometer and shift info; and a smartphone Lap Timer app that syncs to the car via USB.
