Rumormill: Aluminum and carbon fiber, KERS-equipped BMW M5 cometh?
Not surprisingly, we're told to expect a version of the twin-turbo V8 that currently powers the M division's hi-po X5 and X6 tallboys with somewhere around 570 horsepower and 500 pound-feet of torque. On top of those prodigious figures may very well be a Kenetic Energy Recovery hybrid setup to recapture wasted energy from braking. The stored power would be used to send an extra shot of power via an electric motor contained in the seven-speed dual-clutch transmission. The KERS power boost reportedly would be controlled by the driver with a Formula 1-style button on the steering wheel.
Further performance would be found by putting the next-gen 5 Series on a diet consisting of a chassis wrought completely in aluminum with carbon fiber used in various body panels and optionally on the roof. We look forward to finding out just how much of this rumormill material turns out to be accurate, and we'll know for sure in early 2011 when the next M5 is slated for introduction.
