Mercedes have insisted they do not plan to ease off in the final four races of the Formula One season to concentrate on the arrival of Lewis Hamilton next year to replace Michael Schumacher.

Schumacher established himself as the most successful driver in F1 history in his 22-year career with Jordan, Benetton, Ferrari and Mercedes, including a three-year retirement from 2007-2009.

But the German now has just four races remaining this year with Mercedes before his retirement and the team said they are committed to a competitive finish to their season.

Team boss Ross Brawn said they will not switch all their resources to working on next year’s car.

“We need to keep a balanced approach,” said Brawn.

“Our chassis team are designing next year’s car and there are certain directions they want to confirm.

“The aero changes in Korea with the rear wing are primarily for next year. So there is a mix. But, we don’t want to sacrifice the remainder of this year while working for 2013. We still want to have a respectable performance for the rest of the year.”

Schumacher took up motorcycling in his previous retirement, but insisted that this time he is adamant about turning his back on motor sport.

“No, it’s not in my plans,” Schumacher said.

“It is a relief, because I have no regrets, just joy for what I’ve done. From now on, life will offer me plenty of new possibilities. I’m looking forward to them.”
