Official - The New V8 Power Unit For The Bmw M3

I hope the m3 doesn't weigh more than 3500 lbs, although I am guessing it will weigh the same or only slightly less than the 335i. Probably 3550 lbs. If so I'm not sure I would buy one for 65-70k. 3450 lbs and I'm sold.

50-100lbs is a deal breaker for you? Alot of people are making really outrageous claims about this car.

This is great news. I expect that the 420 to be conservative much like the 300 or the 335i or the 507 of the M5/6 are. They are running hotter cams than the M5/6 based on where the peak power is occuring. Real crank power is probably closer to 440.

No need for underdrive pulleys. Sweet. Not clear from the specs if this effect is added to the power graph. The ability to disconnect the alternator on demand is much nicer than underdriving it.

Engine is lighter than the old M3 engine as predicted here

Depending on how much they beef up the chassis over the 335, the full car can/should be lighter.

The powerband is also much wider than the outgoing M3. Basically an awesome job by BMW.

Sure. When I am spending 65-70k on a car, I want it to be just what I want. 100 lbs is a lot of weight. I guess I am just a picky person. I might just save up for a Porsche GT3.
