Next BMW M5 to cut CO2 emissions by 20%, no hybrid
The next generation of BMW's 5-series sedan is expected to debut early in 2010, perhaps at the Geneva Motor Show. The new M5, however, likely won't be launched until the 2011 Frankfurt show. According to Albert Biermann, development boss of the M division, when it does arrive, it will cut CO2 emissions by 20 percent compared to the current model. To do that, BMW will follow an increasingly common path with direct injection, turbocharging and revised gearing. The M5 will apparently use a version of the 555 hp turbocharged 4.4-liter V8 from the X5M/X6M. The increase in torque from the 383 lb-ft at 6100rpm of the current 5.0-liter V10 to around 500 lb-ft at 1500rpm will allow BMW to use much taller gearing for lower engine rpms.
Contrary to some earlier reports, the M5 will not use any kind of hybrid or KERS system. Biermann told AutoCar that the hybrid system from the new ActiveHybrid 7 would add over 200 pounds to the car. Instead, the cars weight will be reduced further through the use of carbon fiber body panels for the roof and trunk-lid.

Looks like all car makers are going green. All super car makers should adopt the greener way.

Buy the current one, and keep it.
Designing a car for the fuel test cycle, we'll probably have to wait till driver input is totally eliminated, before that matches reality.

I know a company that's tired of paying extra taxes on their gas guzzlers!
I bet the used v10 models are gonna go for a pretty penny - what a motor!
On that note, i'm very glad CAFE is tightening up. Suddenly we have small turbo 4's in ordinary cars, direct injection, electric vehicles, and v8's are dissapearing.. hmmmmmm, funny coincidence.

There isn't any reason that BMW couldn't have used taller gearing with the current M5.
200mph@8000rpm in 6th would have been nice.
Have 7th be 30mph per 1K, that would have still allowed 180mph@6000rpm.
If BMW uses the ZF 8hp90, and if 500ft-lbs are available at 1500rpm, then top gear could be 50mph per 1K.
200mph@6000 in 6th, if not faster.
Also will BMW use thinner oil? 10w-60 is like tar.
