• 26 lb heavier than 335i engine!
• 84 lb lighter than M5 S85
• Torque sounds low IMO and at the totally wrong rpm. Max torque in M5 S85 is @ 6100 rpm.
• ++++1 if this sucker revs to 8400!

Don't tell me that the car is only going to be rocking 420hp.

Re: Official: BMW M3 E92 Concept

Nice coupe, front-end is not as "stylish" as rear-end ...! But don't know, why I like "E-46" more, there is something special in it ...!

Hmmm, what does the RS4 engine weigh? I know the RS4 has 430.00 NM (317 Ft-Lbs) @ 5500.00 RPM, so that is higher already if this is true.

I don't like those M3 numbers at all Eni I want more power (at least 430 hp) and more torque, at a much higher RPM. This is supposed to be a high revving car, not a diesel or turbo!!!

Re: Official: BMW M3 E92 Concept

So it still weighs more than the M156?



Edit: Excellent torque curve though.

Is that pic real? M V8 badge looks fake.

the number is 426 swedish horsepowers. I told you guys this a few months ago and its been on the net for months. So this shouldnt be shocking at all.
A more powerful engine is only for M3 CSL.

If BMW keeping the weight low, 420hp should be enough.

POTENTIAL Leaked engine specs:

OK guys, I was hesitant to post this because I could not verify it myself. Seems a bit fishy. However, I have seen the same data posted here, and elsewhere. However no sign of it at the Road and Track website. It is also hard to believe that this was pulled from an off the shelf magazine and someone does not already have it scanned and posted here. Anyway the post here claims that R&T claims the info is straight from BMW. OP makes some very nice analysis vs. RS4, 335i, E46 M3 and E60 M5 power plants as well.

420 bhp @ 8300 rpm
295 ft*lb (400 Nm) @ 3900 rpm
compression ratio: 12:1
redline: 8400 rpm

Re: Official: BMW M3 E92 Concept

I also read the engine is going to develop 340 Nm at 2000 rpm Thanks to the Double Vanos.

Re: Official: BMW M3 E92 Concept

Klier I need your help its in Dutch

what does it say here
BMW M3 met V8 heeft 420 pk, AutoTelegraaf nieuws

De krachtbron met een blokhoek van 90 graden heeft een gewicht van 202 kg. In vergelijking met de 3,2 liter zes-in-lijn motor (343 pk) uit de vorige M3 een gewichtsvermindering van 15 kg. Een en ander is bereikt door bepaalde onderdelen van composietmaterialen te vervaardigen.


does the new engine weigh 15 kg less or more than the M3 E46 engine?

420ho is disappointing, hopefully the whole package is more impressive.

Re: Official: BMW M3 E92 Concept

Just realized that there's a mistake in the PR. On the first page the redline is at 8.300, but in the dyno chart the redline's at 8.400

Re: Official: BMW M3 E92 Concept

Although I'm dissapointed with the power figure I'm quite impressed that they have been able to squeeze out 420 out of a 4L engine. One thing I wonder is if this new M3 is a sign that BMW has pulled out of the horse power war?

Now you sound like a ....!

Why is that dissappointing? What did you expect? 500? C'mon...

Re: Official: BMW M3 E92 Concept
