Rumormill: Aluminum and carbon fiber, KERS-equipped BMW M5 cometh?

What does the future have in store for BMW's high-performance M division? For starters, lots and lots of power, along with a smattering of light weight and plenty of cutting-edge technology. This all sounds familiar, but the rumored details coming out of Bimmerfile suggest that the 2011 BMW M5 would be nothing short of revolutionary.

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.

BMW creates an M5 CSL, and no, you can't have it

To celebrate 25 years of the M5, BMW has created a one-off version of the E60 super saloon that Albert Biermann, head of BMW's M division calls, "the M5 CSL we never built."

The transformation began with a modified version of the standard M5's 5.0-liter V10, which has been stroked to 5.5-liters and fitted with a carbon fiber intake, secondary oil cooler and a new fascia. BMW remains mum on official power figures, but Biermann says the mods are good for around 580 hp and 400 lb.-ft. of torque over the standard 507 hp engine.

Mated to the modified mill is a fortified version of the seven-speed dual-clutch Getrag gearbox fitted to the current M3, while a carbon fiber roof joins a set of lightweight, carbon fiber seats up front. That, combined with the removal of the rear seats, sheds around 110 pounds from the M5's curb weight.

Although performance stats haven't been released, BMW says the M5 CSL laps the Nurburgring around 20 seconds faster than the standard model, so something around the 7:50 mark isn't out of the question. What is out of the question is the opportunity to buy the CSL. BMW has no plans to offer it to the public, and to that we say... fine. We'll wait for the twin-turbocharged V8 version coming in 2011.
