BMW unveils E92 M3 GT2 ALMS race car - 485hp | 500nm | 1150kg !!

[swamp2]

Assuming a 8750 rpm redline and a tranny that shifts approximately as fast as a DCT and tansmission ratios similar to the production E92 M3 M-DCT (not all that likely on the last point) this sucker should be be good for approximately:

0-60: 3.0 sec
0-100: 6.5 sec
0-150: 13.8 sec
1/4 m: 10.7 @ 132 mph

swamp, suppose we somehow cut the production E92 M3 to 2500lbs like this car. And did nothing else (again, just theoretical). What would its times be?

The race car will not rev anywhere near as high as you are assuming.

Wow, really? I'd love to see the source of that info so I can learn about why this is. Got a link? M3 PTG cars rev'd to 8K+ (8500 if I recall), higher than the production M3. I wonder why the P65 would not?

I do not have a link, but the info is accurate. I was as surprised to learn it as you seem to be.

A production M-DCT car with 2500 lb wet weight with passenger and 30 lbs fuel would be something like:

0-60: 3.3
0-100: 7.0
0-150: 16.0
1/4: 11.1 @ 127

That's kinda what I thought too swamp. So really, the weight savings appear to be providing the lion's share of the gains for the race car. Not that the car is anywhere near DOT legal.

Power to weight is the real factor. Stock M3 (EU figures):

1655/420 = 3.94 kg/hp

GT2 ALMS:

1150/485 = 2.37 kg/hp

Weight change vs. power change:

1655/485 = 3.41 kg/hp
1150/420 = 2.73 kg/hp

Or perhaps more simply you could look at:

(1650-1150)/1650 = 30% weight reduction
(485-420)/420 = 15% power gain

So indeed the weight is the much bigger factor. That will not only help acceleration but will GREATLY improve handling.

Yep.

I'd love to see a tuner company specialize in lightening cars. It would be interesting to see how light a production M3 can be made while still remaining safe, legal, and comfortable. I suppose the CSL will give us some idea of that.

Sorry, but that car is FUGLY!

I love the internet. Say it comes from a JDM tuner, this body kit is rice. Coming from BMW it is revolutionary and AMAZING, blah blah blah. Some people just have no taste and simply follow the crowd. This thing is an eyesore and BMW should be ashamed. Plain and simple.

You have no clue what you are talking about. This is not a street car, its a race car. Styling cues and aerodynamic elements that are perfectly at home on race car can easily be complete nonsense on a street car. In fact that is where the term "rice" was born. Is this really a new concept for you?

Its pretty ironic - you fling this opinion out which is rooted heavily in ignorance and then you rip on everyone for "following the crowd". Maybe the reason you are not in step with the crowd is because you are simply way off base? Think about it. Or not, and continue to insult people at random, live in denial, and just generally make a cock of yourself.

The appearance of the M3 GT2 ALMS racer is not the work of some stylist at BMW or a tuner, but the result of wind tunnel testing and Albert2 (the super computer working on CFD at Hinwil). Styling doesn't win races, aerodynamic downforce and efficiency do.

some cool pics

If BMW ever had the balls to make this car a customer car, they would blow away the ancient 911s.

Still with this GT2 and surely a GT3, BMW is going to dish out some punishment on Porsche....

Haha Porsche, all your base belong to us......BMW

Are you really as dumb as your post would indicate? You don't like the way that a functional race car looks???

What do you want leather? How about airbags?

Stick to know what you know best.....matching interior and exterior colors or needlework.

I want one!!! lol!

BMW should make a GT type version of the M3. Something like that to rival the porsche GT3 would open a can of woopass on the unsuspecting 911s
