First BMW unveiled the new F10 M5 as a concept in April at the Shanghai Motor Show. At that time, no technical details were available. However, there were some rumors about its engine.
Yesterday the German publication Autozeitung unveiled first official specifications.
The new 2012 BMW M5 F10 will be powered by the S63 engine; an engine that powers the actual generation X6M and X5M. It produces 560PS (552hp) / 680Nm (501tq).
BMW’s S63 engine
With virtually the same block as the revolutionary N63 4.4l reverse flow V8 as in the 750i and X6 xDrive50i, the M engine – the S63 features significant revisions in nearly every other aspect. Two turbines are positioned together with the catalytic converters in the “V” section.
Practically by reversing the flow of gases through the engine from traditional arrangements, the intake and exhaust ducts are shortened and widened. The result is a low turbo lag while maximizing combustion efficiency and power output.
The managed flow of exhaust gas provided by the Cylinder bank Comprehensive Manifold ensures high-velocity flow of combustion gases. The appropriate separation of exhaust gas flow from different cylinders is maintained until the gas reaches the turbine wheel, spooling the two twin-scroll turbochargers without back-pressure. With maximum boost pressure, the use of twin-scroll twin turbo technology and the patented exhaust manifold allows complete exploitation of the benefits of turbocharging.
What all of this plumbing and forced induction produces is 560hp at 6,000 rpm and 500 lb-ft of torque from 1500 to 5,650 rpm with reportedly no perceivable lag.
