The first-ever eight-cylinder to power a BMW M3
After 15 glorious years in the world of motoring, the straight-six power unit lauded time and again as the Engine-of-the-Year in the two former model generations of the BMW M3 is now giving way to a truly worthy successor: The new BMW M3 comes for the first time with an eight-cylinder power unit. And the specifications of this all-new high-performance engine clearly prove the competence and skill of the engine development specialists at BMW M GmbH gained in a long history of racing success: Displacing 3,999 cc, the new V8 develops maximum output of 309 kW/420 hp, together with peak torque of 400 Newton-metres or 295 lb-ft at 3, 900 rpm. Perhaps an even more outstanding fact is that some 85 per cent of the engine’s peak torque remains available throughout the enormous speed range of 6, 500 rpm
Production of components using know-how carried over from Formula 1
The engine block featured on the new eight-cylinder comes from BMW’s light-alloy foundry in Landshut near Munich, which also builds the engine blocks for the supreme racing machines entered in Formula 1 by BMW Sauber. The crankcase is made of a special aluminium/silicon alloy eliminating the need for conventional cylinder liners, since the cylinder surface is formed
instead by exposing the hard silicon crystals integrated in the alloy. The ironcoated pistons thus run directly in these uncoated, honed cylinder bores.
With the high speed of the engine and high compression forces obviously exerting extreme loads on the crankcase, the crankcase is compact and particularly stiff in its bedplate structure, ensuring very exact support of the crankshaft. Made as a complete forging, the crankshaft is very stable in terms of flexural and torsional stiffness, but nevertheless weighs a mere 20 kg or approximately 44 lb

ისე მაგრა გამიკვირდა ჩვეულებრივი მექანიკა ახალ M3 ზე რავიცი რავიცი!
330 კმ მაგრა გამისწორდა რა!!!
ბარემ ბაგაჟნიკიც ვნახოთ და ვსიო
