I am yet to see a single (fully stock) 1M dynoing less than 550 nm (410 lb.ft) of torque and less than around 350-360 bhp which will be quite "difficult" to match for any 2 liter/4 cylinder engine. And I assume BMW will not bring us a totally stripped E46 M3 CSL style car as the new M2 to the market, just to compensate the lack of displacement and power. It will have all the modern goodies and will weigh close to a 1M, maybe slightly lighter, that's all. The same will go for new M3/M4.
If you want a totally light and super efficient rwd sports car alternative, like me, wait for cars like Alfa 4C which may hit the markets including US even before than a possibly 2014 if not 2015 model M2, news tell us to expect a 4C around a year from now. It will have around 250 hp from a 1.7 liter turbo four, weigh a crazy 900 kg. or less (oh yes), rwd, mid engine, CF chassis and body parts, DCT transmission and bold styling inside outside with a price tag similar to a future M2 which should also mimic a 1M. All these are confirmed by Alfa. Otherwise everyone, if you want to stick with BMW then BMW is already telling us how a M2 will be if you read between the lines and watch closely the M135i or 1M.This road is going to only one direction and I don't see any lightweight turbo-4 M car at the end of it.
That 4C really does look like a sweet track ride!
