More details regarding the facelifted M3 Coupe and Convertible have been released recently by BMW. The press release highlighted that the only alteration made in design is the rear taillight.
Auto Start-Stop technology
Another interesting feature of this high performance vehicle is the addition of the Auto Start-Stop technology, which is made available in all thee variants of the M3 i.e. the coupe, convertible and the sedan.
BMW has made this technology available in both the manual and the 7-speed dual-clutch transmission options. BMW elucidates the advantage by stating that this system shuts down the engine when the car comes to a stop, hence enabling the BMW M3 to save about 8% on CO2 emissions. Fuel consumption is also reduced to 11.2 litres per 100 kilometers (M3 Coupe with DCT). So now it'll be an unusual experience as on stopping the M3, instead of hearing a rumbly V8 note, there will be silence!
