2012 BMW M6: Armed with a big TwinPower Turbo V8 engine, the new M6 is here to deliver a 560 HP ass-whooping to the CTS-V and any other coupe with the balls to get in the ring with this Teutonic two-door. But, if you're hoping for a manual don't hold your breath. At least not this year anyway. That engine's the same one already found in the BMW X5M, X6M and M5.
The 4.4-liter engine develops a peak output of 560 hp at 5,750 – 7,000 rpm, while its maximum torque of 500 lb-ft is on tap between 1,500 and 5,750 rpm. The rev limiter intervenes at 7,200 rpm. The rev band is therefore almost three times as wide as that of the V10 engine in the previous generation M6. Not too shabby if you ask me. As in the V8 engine of the X5M, the two twin-scroll turbochargers are placed (along with the catalytic converters) in the V-space between the two cylinder banks in a reverse flow layout.
