Renault to reassess KERS use

Renault will make a decision on when it will reintroduce its Kinetic Energy Recovery System (KERS) within the next fortnight

Renault to reassess KERS use

The French car manufacturer started the season using KERS but did not enjoy as big a benefit as it thought it would get - and dropped it completely for last weekend's race in Spain.

The team has already ruled out using KERS in Monaco and executive director of engineering Pat Symonds says it will decide on whether to reintroduce it for the Turkish Grand Prix soon.

When asked by AUTOSPORT about the team's plans for KERS, Symonds said: "We obviously made a fundamental decision not to attempt to run it in Spain, and a decision not to run it in Monaco.

"I think we will reassess Turkey, because what we have been doing in the last few weeks is getting all the data together and just trying to see where our simulations need improving. So we need to make a decision on Turkey in the next two weeks - not before that."

Symonds said that the decision to drop KERS for Spain came after the track experience from the first few races showed the advantages of the system were not as great as simulator work had predicted.

"On our initial simulations, it was lower down the pecking order, but I would have said still worth while," he said.

"But as we adjusted those simulations in light of experience, because no matter how good you do your simulations you still need some fiddle factors in there, I think as we understood more from the first few races after testing, and it dropped off the good list. It dropped down to a no, we won't do it."

Symonds has also said he is baffled by some teams choosing to keep KERS on their cars for the Monaco Grand Prix.

"To me it is just no way for Monaco," he explained. "I could be quite rude, but I can't think who would think it is good.

"If you think about it in simple terms, Monaco is not a power circuit so you will not get the advantage anyway. You cannot get the power down there, and you can only use KERS when you are not traction limited, and you are traction limited for a very long time at Monaco. It is definitely not on our radar."
