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.
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.
It means there is unlikely to be a repeat of the graveyard shift that saw the mechanics work until 3am on Saturday morning at Silverstone replacing the system.
If hopes McLaren have cracked the problems turn into reality then Button and Hamilton could finally find themselves on the same playing field as title rivals Mark Webber and Sebastian Vettel.
"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."
