Nico Rosberg, Mercedes, Hungarian GPMercedes team boss Ross Brawn says his outfit will switch its focus to the 2011 car following the end of the summer break.
He said Mercedes will work on one more upgrade package that will be introduced during the Singapore Grand Prix, but admitted the main priority will be the new car once the summer break ends.
"I think there is one more step we want to do before the end of the year to take full advantage of the low exhaust position, that is something we will target for Singapore," said Brawn.
"That was coming through already but clearly after the break our priority will be the new car."
Brawn conceded the team had not been able to extract the maximum from this year's car, and felt there was no point in continuing to spend time on it.
"There were another set of regulations this year with no refuelling, and one or two other things," he said. "We didn't perhaps hit the sweet spot with the current car, so I don't think we will throw much more resource at it.
"We understand what we need to do next year and that is where we are putting our major efforts."
