Championship leader confident Brawn back to their best in Hungary
Jenson Button has said there will be no excuses if Brawn GP fail to improve on their recent poor showings at this weekend's Hungarian Grand Prix.
The Englishman built a runaway lead in the championship thanks to six victories in the first seven races before Brawn GP's principal rivals so far this season, Red Bull, hit back.
The latter's drivers, Sebastian Vettel and Mark Webber, scored successive one-two finishes - each winning a race - in Britain and Germany to emerge as title contenders.
Button still leads Vettel by 21 points in the standings but, with Brawn's car struggling in the cooler temperatures of northern Europe, the move to the 30-degree heat of Budapest cannot come soon enough.
He said: "There are no excuses.
"It's hot, we've got the temperature now, which is great for us, so saying we've no more excuses means there is not that (the weather) to fall back on.
"We've some updates, mostly aerodynamic, that will move us forward a good chunk.
"Although you see what it says in the wind tunnel, you don't know whether it's going to be reality on the circuit.
"But I'm happy with the step forward and hopefully it'll be enough to challenge the Red Bulls and make it more exciting.
"Certainly we have everything to play for this weekend. They will have us to contend with here - in the last races they didn't - and we'll be pushing them a lot more.
"But we have to start beating them and challenging them again, otherwise they will take too many points off us.
"They've already taken 11 points from me in the last two races - that is too many."
Potential
Although Button finished only 13th fastest after Friday's second practice session at the Hungaroring, he feels it is not indicative of his car's potential this weekend.
"I'm happy with the way things are going," he confirmed.
"There's still some work we need to do to be really competitive, but our pace is good, and the direction we are taking with the car is the correct one, and I'm happy with the balance.
"I don't know where we stand after today. I was 13th, but we're quicker than that, and I feel we're in reasonable shape.
"We won't know until qualifying, but we're in a better position than we were in the last two races.
"So I'm happy to be here and in a position to drive this car, and it's a good car to drive here.
"I don't know if it's the same as Turkey, but it's nice, and I haven't felt that for the last two races."
