Mercedes Engine Boss Andy Cowell Rejects Ecclestone’s Hybrid Claims
But Mercedes F1 engine boss Andy Cowell said that road cars would soon be using "exactly the same" technology. Two separate hybrid technologies are being used in the F1 engines, which were introduced last season. One "recovers energy from the rear axle during braking, stores it in a battery and reapplies it under acceleration."
This is "exactly how current hybrid road cars work." The second — and new — technology "recovers energy from the turbocharger shaft." It can be "applied directly to the rear wheels to boost acceleration, and it can be used to prepare the turbocharger system so it is ready to be used as soon as the driver presses the accelerator." Cowell said that this system would "definitely" start appearing on road cars. BBC
