BMW has joined the hybrid bandwagon in a big way, contributing to greener cars, with lower carbon dioxide emissions. While its M series of cars is extremely fast and performance and speed oriented, BMW will probably use the KERS hybrid drive system on the new M5 model which is being designed, though the car will not be available till 2011.

In all likelihood the high output version of the new 4.4-liter V8 like the one in the X6 M will replace the 5.0-liter V10 in today’s M5. It is also possible that BMW will add a power on demand button which will use available power to boost engine power. Though there are rumors that two cylinders will be added, this is unlikely because the increased torque on the V8 should be sufficient to give higher performance with lower weight.
