2015 M3 specs released

[posterchild336]

You hit the nail on the head. BMW has purposely underrated all of their turbo cars for this very reason. I would say that torque will be around 400 ft/lbs stock.

Closed deck = More boost = Race Car...

Of course..I am a BMW enthusiast, we had our convos in the past here on the coli..I have M and had the 335 like yourself...we know how they operate...oh and yeah you are right with stock lbs of torque

Look at this shyt

I'm guessing this is just simulated? No way is the torque curve that flat all the way to 5250. Good to see the engine doesn't lose power above 5250 like the 335i as well.

Believe it.. I the m now is linear all the way to the redline... High revs is where the car shines unlike the 335 that drops on power after that high range

Yes, they can make a flat torque curve like that by playing with timing and boost and measuring load. Mercedes does it on all of their turbo motors to protect the transmission.

Theyy are saying its going to weight more like 3500lbs once it gets to the US. Still, it should be a pretty fast car.

The high rpm power loss of the 335i is a function of the puny stock turbos not of the engine itself.

Uh yeah, that's totally simulated. You might as well have posted a dikk pic and called it the powerband.
This is what a turbo powerband looks like.

That's for a Borg Warner turbo. You can see the HP and Torque powerbands criss cross around 5500 RPMs. That's similar to the Cobb Tuning graph two posts up, but that one crosses around 5250 RPMs.
This powerband is tell-tale of a big scroll that has turbo lag. Between 5300 RPM and 6900 RPM, the turbo kicks in and the curve goes up exponentially rather than linearly like in a N/A car. This is a race car-prepped B-series Honda engine so the RPMs go beyond 9000 RPMs. The Cobb tuning chart shows that engine peaking at 7200 RPMs.
