The M3 Sedan and M4 Coupe can be ordered in Alpine White, Sakhir Orange, Black Sapphire, Silverstone, Mineral White, Mineral Grey, Austin Yellow and Yas Marina. The launch colors are Austin Yellow for M4 and Yas Marina for the M3 Sedan.
Under the hood, the two Ms feature the return of the inline-6 engine format made famous by BMW M. The all-new, 3.0-liter BMW M3 and M4 engine is approximately 10 kilograms lighter than its V-8 predecessor and packs an even stronger punch.
With 425 horsepower from 5,500 – 7,300 rpm, 406 lb-ft of torque from 1,850 – 5,500 rpm, and capable of 0-60mph in 3.9 seconds when equipped with the M-DCT transmission (4.1 seconds with standard 6-speed manual).
DTM drivers Bruno Spengler and Timo Glock took part in the extensive testing and set-up work carried out at the Nürburgring-Nordschleife circuit.
BMW M has put the M3 and M4 on a serious diet, managing to wring 176 lbs (80kg) out of a similarly equipped 3 or 4 Series.
Both cars will debut next month at the 2014 Detroit Auto Show.
