Speculations about the E90 M3 have been zipping around in some circles about the possibilty of the M3 going after the C6 Z06.
It is being rumored, though no way to confirm it at this point, that the reported power output of 400HP is too low, and that it is closer to 475HP, with a possibilty of the displacement being closer to 4.5Liters, bringing the bhp/L a little higher than 100. With the E90 bing lighter than the E46, this should be a great omen for the power/weight ratio of the M3.
What is interesting about this is that the M Roadster will be recieving the same V8, though more than likely detuned slightly as the E36/7 M Roadster put out a mere 315HP@6800RPM comapred to the M3's 333HP@6800RPM. However, the E85 M Roadster will have a better power/weight ratio to compensate. Though it is not going to come close to the E60 M5, it should comfortably carve it's niche not too far below.
wether or not the M3 will be 32HP weaker than the M5, it will still be a potent machine and a force to be reckoned with. But should this rumor come out to be true...RC is going to be sweating bullets when he checks his rearview
