Teams using ‘kickdown’ approach to trigger KERS

(GMM) Four teams are using an innovative method to maximize the driver's ability to efficiently deploy KERS in 2011.

That is the claim of Germany's Auto Motor und Sport, describing the novel method as 'kickdown'.

'Kickdown' refers to the additional pressure that a driver must deploy beyond full throttle to activate the KERS power-boost.

It means the driver, who is already at full throttle when he needs to use KERS, must do nothing other than press even harder on the right-foot pedal to trigger the energy-recovery system.

Nick Heidfeld confirmed that he made the 'kickdown' suggestion for KERS when he joined Renault this season.

"I had the idea to use kickdown when we had traction control," the German is also quoted as saying. "We did that at BMW."

Another clever innovation in 2011 is in the Mercedes footwell, where Michael Schumacher and Nico Rosberg rest their foot on a third pedal to the left of the brake to activate the DRS rear wing.
