When BMW first announced that the BMW Sauber F1 team would be implementing electric KERS, they had this to say: “The BMW Group can transfer the knowledge gained within the BMW Sauber F1 Team directly into the development of standard production vehicles. This makes Formula One the ideal pre-development platform for innovative drive technologies.”
And it looks like it really happened after all! It seems that the next generation F10 BMW M5 will have a type of KERS system! Scott27, a BMW insider of sorts on the German Car Zone forums has revealed that the final engine to be slotted into the next generation F10 BMW M5 has not quite been decided yet. But what is confirmed is a kind of KERS system that will be exclusive to the M5. It will forge a big link between BMW M and BMW’s EfficientDynamics program because it will be taking what is essentially wasted energy but recycling it and turning it into power.
As BMW’s F1 cars uses a electric implementation of KERS, the BMW M5’s KERS system will likely use Brake Energy Regeneration to recover energy and store it via some kind of battery of supercapacitor system. This energy can then power a high-powered motor that can boost up power by a certain amount for a few seconds.
The F1 car’s KERS system weighs under 40kg and stores enough energy under braking for 60kW of output for 6.5 seconds. BMW picked an electric KERS system instead of a mechanical (flywheel-based) or a hydraulic system (abandoned) likely because it was already using similiar technology in the EfficientDynamics program and it would be easier to transfer the knowledge gained to production road cars.
Back to the engine – there are two engine options being evaluated right now. One is very likely some form of tuned up version of the same M TwinPower Turbo V8 engine in the X5 M and X6 M, but the other is something a little more exciting than that, though it was not revealed towards which option management is leaning towards.
