"Who wants to be world champion this year, should have the KERS. That was the assertion of the former director of BMW, Mario Theissen.
This phrase was spoken in 2009 when the energy recovery system known as KERS was introduced for the first time in Formula 1. Now, the hybrid system has returned to formula one and there who says that this year will be crucial.
"In the car in front, would be rare to not have the KERS", now says Rob White, head of Renaul engine in an interview with TMS.
It is clear that the KERS has changed for the 2011 energy recovery technology works better than in 2009 because conditions have changed even in performance: once, every driver for a period of 6.7 seconds presses a button will give an extra 82 HP (60 kw).
In 2009, the KERS was a great disadvantage because the minimum weight of the car at that time was 605 kg and the weight distribution was heavily affected - in some cases, the 605 kg exceeded even to assemble just the KERS. 2011 Estimated that the new KERS units are compact and light.
"It was 2009, there was a legitimate debate about whether the KERS was an advantage," explains White adding that in 2009 might have been more determinant if not would have limited the power of the system.
Now in 2011, with the return of the KERS, does the system be decisive?.
