Button hopes for step forward

Jenson Button has every faith the McLaren that will be unleashed at this weekend's German Grand Prix can tame the mighty Red Bulls.

Both Button and team-mate Lewis Hamilton will again put the team's performance-enhancing exhaust blown diffuser through its paces in Friday's two practice sessions. It was a device that was ditched after Friday practice ahead of the British Grand Prix a fortnight ago due to a number of issues. But after further time to research and develop the concept since then, there is belief the team are firmly on the right lines on this occasion.

"Everyone has done a great job of staying calm when we know we don't have the quickest car," said Button.

"We've won races, we've been competitive, we've been on the heels of the Red Bulls, so we're doing a good job.

"The car itself is a good car, it's just the Red Bulls have been moving forward at a rate of knots.

"So if we can get this update to work it will be fantastic, and I know the team has done the best it can to make sure we get the best out of it this weekend.

"Hopefully we'll see the improvement. If we don't, we'll still work with it and improve the car around it because it does take a bit of time.

"At Silverstone it's not that we were losing out, we just didn't gain as much as we expected.

"For here we'll hopefully gain the full amount of what we expected. There isn't a reason why we shouldn't."
