Improvements likely for Hungary - 4th August 19:45pm GMT

Michael Schumacher will have an improved Ferrari at his disposal in Hungary next week, but technical boss Ross Brawn has warned he has little more to give the world champion.

Brawn, Ferrari's technical director, has overseen an improvement to the car, which has already been good enough to power Schumacher to 11 wins from 12 races this season.

Schumacher has had to fight harder for his wins in recent races as the likes of Renault and McLaren reaped the rewards of their development programmes.

Now Ferrari will hit back with new parts for the Hungarian Grand Prix but Brawn is warning that is likely to be the end of the improvements.

He said: "In Hungary we should have another step on the tyres but the chassis is probably frozen now for the rest of the season.

"There are small bits on the engine but most of the performance gain for the rest of the year will come from the work we are doing with the tyres."
