MMMM .... YEA!
A 4 point "Oh!" Litre ... V8 Engine ... pumping out 4 hundred and 20 Horses (420)!!! INSANE!
Best part is ... the new engine is 15 pounds lighter than the previous Inline 6 engine!!
"It's one hell of an engine, too. The crankcase is made from an aluminium-silicon alloy that does away with the need for cylinder liners by allowing the pistons to run directly into the cylinder bores.
The V8 also gets BMW's variable double-VANOS camshaft control, which keeps valve timing quick and improves engine output and torque.
Each cylinder gets an individual throttle butterfly, too, giving a more immediate reaction at low revs.
Technical, yes, but what it means is that the M3 can serve up 85 per cent of its peak torque - 295lb ft of the stuff - across the entire rev band.
The M3 should have the real-world performance to go with the stats, too. With the exception of the doors, bootlid and lights, all the rest of the M3's body components have been developed bespoke.
Most importantly, that includes the carbon-fibre roof promised in the concept. Not only does it look cool, it'll keep the M3's centre of gravity low." [Extracted from TopGear.com]
