REVOLCAR: KERS

From 2014 the Formula 1 race cars have to move in the pit lane just using the KERS electric motor. But Bernie Ecclestone, a self admitted climate change denier, believes it is too dangerous.

According to the regulations submitted to the FIA, the energy accumulated on the braking, shall actuate the motor during the movement of the pit lane.

"To go on the electric motor on pit lane would be dangerous, because people who are there will not hear the machine – says Bernie. – Also, the absence of sound affect the interest of viewers. Now, as soon as the GP3 race starts, where the sound of the engine is almost inaudible, the stands begin to thin out. Electric motors have no place in Formula 1. "

Renault team boss Eric Boullier is among a number of Formula One personalities to express fears that plans to make cars run electrically in the pits from 2014 is too dangerous.

The proposal that "the car must be run in electric mode (no ignition and no fuel supply to the engine) at all times when being driven in the pit lane" was included in the governing FIA's new 2014 regulations published last week.

Other environmentally-friendly ideas were also adopted but some teams feel they were not adequately consulted on the changes by the governing body.

"The concept is intriguing but... the cars would not make noise and that could be very dangerous," Boullier told reporters at the German Grand Prix.

"I think there are aspects of the rules published by the FIA which should be looked at again."

Formula One is due to switch to a new 1.6 litre turbo V6 engine with energy recovery systems from 2014. The sport currently uses V8 units.

Boullier is also keen on an extra practice session rather than just two on a Friday from 2012 while teams continue to talk with the FIA about a return to some form of in-season testing from next year.
