• 2014 BMW F80 M3 expected to weigh 220 pounds less than the E90 M3 and have 450 horsepower?

      Interesting claim here regarding the curb weight of the next generation F80 M3. Now the horsepower is expected to be in the 450 range. CAR Magazine claimed the car would have 444 horses so ~450 seems to be the right range. This not as big of a jump as the E46 M3 to the E92 M3 or the new F10 M5 to the previous generation E60 M5 but BMW only made about a 60 horsepower jump with the new M5 model at the crank although the horsepower numbers at the wheels point to far more.

      I would expect the same with the new M3 that for the wheel horsepower gains on the F80 to exceed the crank horsepower difference presented by BMW between the F80 and the E90 M3's. This power increase combined with a claimed weight loss by 220 pounds would make for an M3 that performs very well.

      The thing is, 220 pounds is a lot to shave off the F30. And if the F80 M3 undercuts the E90 M3 by 220 pounds that means it would weigh somewhere in the 33XX pound range. Owners have weighed their E92/E90 M3's in the 35XX pound range. Confusion arises that the E9X is heavy because BMW lists its European weight which includes a 75kg driver.

      BMW claims the current F30 335i weighs 3555 pounds. So, about what an E92 M3 weighs. That would mean if the rumor for 100 kg weight loss were correct the F80 M3 would undercut the F30 335i and E92 M3 by 220 pounds. That means weight less than an E46 M3 as well, not happening. What is more likely is that BMW will undercut the 3704 pound curb weight they provide for the E92 M3 putting the F80 M3 somewhere in the 35XX pound range or just about the exact same as the E90/E92.

      We will find out soon enough with the car expected at the Los Angeles Auto Show in November.

        I have driven an X5M - that has a "real M motor" - it's not even close to as responsive as my M3. Tons of torque down low, yes - but it's again, not even close - not on the same page/book/etc... I guess it's an opinion, but I am nearly certain it will be true for the next gen M3

        The x5m isn't a good example....that car is even less of a m car than the 1m.

        I know - point is, it has an "S" motor - created by M GMbH. I can see the M3 being a "miniature" M5 - as it has been in the past. They aren't going to get rid of the lag, there will always be some. NA is as good as it gets, that's the thing. By no means do I think the X5M is a proper M car (same with the 1M) - that's the other half of the problem with this nonsense.

        Exactly and it offers nowhere near the response. None of these new motors will, it's not possible.

        that comment doesnt even make sense, put the drink down before you get into more trouble

        You need to take time off from the forum. Please take a break before I make you.

        You're hopeless man. How doesn't it make sense? the S65 is the most powerful engine available for the E9x platform, both modded and stock.

It's just the nature of the motors a turbo motor will have lag. They can bump compression to try to minimize it but it will always be there. Just like how the 911 turbo will never match the GT3 no matter if they use VTG turbos or not.

        I don't think it will be the end of BMW's or a bad car. It just won't be the same.
        I know you were talking N/A here, but let us not forget the ultimate lag of an centri SC. Come on sticky, you would rather have a turbo on that monster of yours. The response is a fact of the motor, not turbo/non turbo. Put a turbo on an E46 and immediate response will be the same, but more power will be had of course. Same with the E92 m3. Your right that the newer motors are a different breed/feel. I think that if BMW built a turbo power plant with N/A response in mind we would see that instant jab followed close by a face rippling surge.

        Don't forget when you are comparing N54 to S65, there are 2 less cylinders and over a liter less displacement. N54 is detuned from the factory compared to S65, and both are on par with each other in aftermarket power abilities. I don't ever see the S65 even hanging with the new TTv8's once the aftermarket really gets their hands on them.

        But, I think BMW should take a page from Porsche and the GT3. There is always a group that doesn't want the turbo surge and larger power capability, but the instant bang on throttle of a highly tuned N/A motor. Id like to see an N/a version M3 as well.

        Wait, so, 2 less cylinders and over a liter less displacement and the N54 still is right up there with the S65 when modded with larger turbos. The n54 is detuned comparatively speaking versus s65 from factory. a lower end tune puts it right in the neighborhood. And what about stock engine/turbo/drivertrane when modded the s65 hangs? Didn't know that N/A s65's put down what a full bolt on w/ good tune n54 can.

        Also, just want to point out that while the modded s65 does hold a higher power level now, that is with a built internal engine and if I recall the 700+rwhp n54's are stock. Apples and oranges man. Lets build the N54, not just the bottom end-add a set of cams that can breath and increase the size of those pea-shooter valves it has and really run some boost.

        If you read the S65 Gintani Turbo thread I say exactly this, do not disagree. I would ultimately rather have a positive displacement big ole twin screw but that won't happen.

        This is due to the S54 being a razor sharp NA motor with very high VE. These BMW turbo motors are not the same thing. It's not like they are taking an S54 and turboing it or taking an S65 V8 and turboing it. Direct injected, lower compression, lazier motors with torque curves that drop off. I would complain a lot less if they combined turbos with their previous M philosophy but alas they do not.

        Oh trust me I never forget to put this out and both ARE NOT on par currently.

        Why not? It's faster than they are on even with an SC on stock internals. By the time the TT V8's can hang with my car...

        I agree Porsche does it the right way.

        It isn't, what are you talking about? And additionally the S65 psi per psi will always outperform it. Always.

        NA S65's have hit 441 whp so they sure can and they could hit more too. It's how you built it.

        No what you do to it there is no way for it to become a 4.0 liter V8 with 8500 rpm. The S65 does have a higher power level and it's much higher than people even realize. Let me get my clutches fixed and I'll show you.
