I am eagerly awaiting the new E92-based BMW M3 to be released to see what fantastic new engine BMW will be putting under the hood. New BMW engines seem to naturally be award winners lately – the 3.0 twin turbodiesel in the BMW 535d, and the normally aspirated 5.0 V10 in the BMW M5.

Details of the new E92 BMW M3 has surfaced on forums like M3 Post, and while we don’t know if this is the actual real specifications, let’s just have a look at it anyway. Details are after the jump.

307 kilowatts of power would be approximately 412 horsepower. The engine has a peak torque of 420Nm. That’s only 20Nm of torque higher than the BMW 335i‘s figures! Looking at the high horsepower to displacement ratio and the relatively lower torque figures as compared to the horsepower, this is likely a normally aspirated engine that makes its high power from sky high revving like it’s older brother the 5.0 V10.

From these specifications, it also looks like it will come in either a 7-speed SMG III computer controlled clutch transmission or a 6-speed manual gearbox.

Of course, remember that these specs are not officially released by BMW, so any dude like you and I could have made them up ;)
