WHAT THIS SHIIT ? 420 hp ONLY !! HMM MM OK
M3 vs WHAT ???!!! 4 LAST yeay bmw tell us M3 for ferrari 360 and por now M3 VS what ?! ok some guys say this car will be good in M3 CSL ! ohh this shit man this car should be 440 HP minmam if u want right CAR !

After digesting this information for a little longer, my initial +ve impression is offset by the following:

Even though the torque curve is relatively flat after 3500rpm, the peak torque of 400Nm only translates into 295 lb-ft of torque. Like the V10 M5, it will likely be lacking in low end torque (especially below 3500rpm) and will need to depend on high rpm to really accelerate. Nothing wrong with that, and completely in line with BMW M philosophy. If the overall weight of the car is low, this car will still fly when driven properly (rev it to the heavens... ).

As a comparison, even the older 5.4L V8 of the C55/SLK55/CLK55 has 400Nm available starting at just 2000rpm, with a peak torque of 510Nm (376lb-ft) at 4000rpm. And we already know the newer 6.2L V8 from AMG has high torque AND high engine speed limit. There really is no replacement for displacement (or forced induction like the 335i) when it comes to torque at low rpm.

I must admit that I am a bit disappointed that they didn't make it a 4.2-4.5 liter but very impressive engine nonetheless. What does the "Engine weight to BMW standard" mean? Propably not dry weight? What's the weight of the RS4 engine?

When i drove the E60 M5 the problem with the car was the torque curve and its lack of low end grunt. Sure it was fun on high way cruises when you can find the perfect gear to rev it in....but still. I hope that 295 lb/ft is good enough...it seems awfully low-even if it is a flat torque curve..

im going to be honest- im dissapointed. Not with horsepower numbers...but with torque numbers..

These specs are correct. Go to the Automobile magazine website for a detailed description of the engine and how it operates. Several pages of technical info. Great read!!

Looks like the 4.2 V8 RS4 engine from audi is the superior engine to the new M3 one on paper atleast. I expected more TBH.

^ no it doesnt. Heres a direct comparison between the engines.

wow, a lot of bitchin' and moaning about this engine when we don't even know what this baby does inside the car.
Must be all those RS4 fans, smelling they must be fast before first numbers come in.

You really think M would underpower the M3? You really think they wouldn't make the M3, their Iconic car, the best in it's class? You don't know already that the theory behind M is lightweight materials, handling and balance, not blunt Bhp or Torque? Good Lord, let's wait untill we see some figures before breaking this car up into little pieces.

Yes but the RS4's got more torque and it kicks in earlier. Some people wont like the BMW's no torque at low revs nature, and I presume those will be the same people that dont like S2000's.

Yep I won't say that the AUDI engine is better than the M3's engine...I would say is that it's on part with it.
