Button hopes for top 10 at home

Benetton has suffered a nightmare season so far, with Button's team mate Giancarlo Fisichell bringing home its only point so far - for a sixth place in Brazil. The 111-degree Renault V10 used by the team is significantly down on power compared to the BMW, Mercedes and Ferrari benchmarks and the team is yet to introduce power steering or launch control for the first time.

Renault introduced an evolution of its engine at Magny-Cours, but did not see a significant leap in performance. The drivers say the new engine is an improvement, especially in its mid-range, but after still qualifying only 16th and 17th in France, Button isn't expecting too much at Silverstone.

"Two cars almost finished in the race in France, just outside the top 10, so a finish in the top 10 is possible," he said. "That will be nice, as it's the home Grand Prix and everything, and we think we've got the reliability to do that, which is good."

Launch control is set to be used for the first time at Silverstone and power-steering is on the cards too - something Button believes is essential for the nature of the circuit.

"I think you need it at Silverstone, because it's very hard on your arms," he said. "If we've got it there I'll be very happy, and I think we will. I did two days without problems (in testing), and we've got some good settings on it. It is a big help, and if we'd had it for Monaco, it would have been even better."

Renault, meanwhile, has downgraded its end-of-season goals, with its sports boss Patrick Faure now saying he does not believe the engine will be showing anything like its full potential until the middle of next season.

"We started the season three seconds off the pace and now we are 2.2 seconds behind," he told Autosport's sister publication Motorsport News. "I would like to finish the season about one second down. By the middle of next season we will be at our maximum speed."
