But...
HP peaks at 7,000.
A move in the right direction, but I wouldn't say problem solved. I did think to myself when reading C&D's review of the MP4-12C (horrible name) the TT 3.8 V8 would probably make a nice M3 engine. It started out as a Nissan engine if I remember correctly. It reportedly gets 22 mpg on the highway and generates well over 500hp, again, if I remember correctly. JB |

Yeah, that engine was first announced over a year ago now. Here's some past discussion from the forum:
http://www.google.com/search?q=McLar...e%3Am3post.com http://www.google.com/search?q=mp4-1...e%3Am3post.com But there's Really no hope of an M engine revving this high since fuel economy would likely be scarcely better than the outgoing S65/S85. |

Don't where you were 1MORELAP, but that is what I was saying already 1 year ago. For all others, the MP4-12C engine is the best turbo engine ever. Well, can't deny the LF-A or the 458 Italia still sound better, but the Macca doesn't sound bad at all, on the contrary it sounds good (though never heard it in real, only vids).
This were my latest realistic and pessimitic specs speculation: BMW M3 F32 TT 3.0l I6 450 PS @ 6.500 RPM 500 Nm @ 2.500-6.500 RPM Redline @ 7.500 RPM I still hope it will be better than this. If not, the car better weigh 1550 kg (EU). Oh and for those who do not know just look at M3 vs. MP4-12C M3 / MP4-12C NA 4.0l V8 / TT 3.8l V8 420 PS / 600 PS 400 Nm / 600 Nm 11,2 l/100km / 11,7 l/100 km 263 g/km CO² / 279 g/km CO² And you know how much faster the Macca is? |

Not sure, but I would not be surprised if it fell off like an N54/N55 (probably not as bad though). One point to it would be to allow the car to land higher up in the powerband when hitting the next gear. I.e you start to lose power in the higher rev range, but you'd be making even less if you had to shift to the next gear earlier.

There are reports coming out through the grapevine that the new Mclaren just blitzed the 'ring in 7:00 dead... That's scary fast... that's make a GTR, 458, GT2RS look slow kind of fast.
Still hasn't been confirmed and we don't know if it was on slicks or street tires but if its true (regardless of the rubber it was wearing) its going to be one hell of a car! |

Interesting info, JB. I didn't know that. So with a 93mm bore, that's 1mm more than the S65. And with less displacement, that's going to be a real short stroke, meaning lower max piston speeds than the S65. |
