Even in the days before Christmas, BMW engineers continue to test the next generation BMW M5 due out in 2012. With the next F10 M5, BMW will continue to emphasize their efforts in the EfficientDynamics program. Further technologies aimed at reducing fuel consumption without sacrificing driving pleasure and performance, are rumored to make their way into the new M5.
The next M5 is all about lightweight construction. The chassis is pressed in aluminum and several lightweight materials are used in doors, bonnet and even roof (carbon fiber). To reduce drag and boost downforce and lower fuel consumption, special Aerodynamic aids that will be incorporated in the front of the car, including the outer-edge of the wheel arches , front bumpers and within the grille intake. Mini turbines are incorporated in the grille to convert drag under braking into electricity.
The new M5 receives a version of KERS utilizing super capacitors. The super capacitor is an electric double-layer capacitor which can have energy densities thousands of times greater than normal capacitors. Super capacitors can also be recharged quickly, transferring what otherwise would be heat energy in the braking process to stored electrical energy.
The KERS functionality will be implemented in the transmission most likely. BMW partnered with several other manufacturers to implement hybrid capabilities in a transmission over the past several years. The ZF eight speed automatic used in the 5er GT and new 5er can be mated to a torque convertor or an electronic wet clutch so there is some possibility that this will be the core of the 8-speed DCT used on the M5.
Although the V10 in the current E60 M5 was a candidate for the next model, BMW M is moving into the direction of twin-turbo high-power engine. The new car inherits the V8 engine found in the X5 M and X6 M, but will suffer further modifications to increase the power. The number rumored at this point is around 580 horsepower. The V8, although shared with the X5M and X6M, is completely individual and unique to the M5. BMW is adapting the engine to suit the M5 and its character, and it is not just a transplant from the other Ms. An important character in an M5 is essentially the engine sound and the new V8 will not be only faster and more powerful than the outgoing V10, but it will also sound just as spectacular.
The V8 will also feature cylinder shutdown to aid with fuel consumption overall figures and a 25-30% more efficiency is expected, when compared to the current E60 M5.
As any other M model, The F10 M5 will feature the M-style front-fascia with larger, aggressive air intakes and of course, the now branded “M” fender vents. Different M-style wheels and other M-like elements will be represented as well in the new design.
The 2012 BMW M5 will debut at the 2011 Geneva Motor Show will production beginning months after.m5board ]
