Mercedes executive director (technical) Paddy Lowe says the team is confident there will be no repeat of the gearbox problems which hit Nico Rosberg at Silverstone.

Rosberg was leading the British Grand Prix from team-mate Lewis Hamilton when he started to complain of problems on upshift, eventually retiring with gearbox failure to hand Hamilton victory. While Lowe said Hamilton's win in his home race was a popular one, he said the focus at Mercedes since the race was to understand the problem Rosberg had and prevent a repeat.

"Silverstone saw a fantastic win for Lewis on the occasion not only of the 50th British Grand Prix, but also the 60th anniversary of the first Formula One victory for Mercedes-Benz," Lowe said. "While this brought cause for celebration, the main priority of the days since has been to understand the gearbox problem we saw with Nico's car and to make sure there is no recurrence moving forwards.

"As with any such scenario, a lot of work has been put into rectifying the issue and we head to Hockenheim with a remedy in place. We will also be bringing a number of other upgrades evaluated during the Silverstone test last week, so we look forward to the next race in the hopes of both improved performance and a more robust package from a reliability perspective."

Rosberg himself said he was focusing on the positives from his performance at Silverstone having retired through a mechanical failure.

"Although it wasn't the result I wanted in the end, my weekend in Silverstone was really encouraging in a lot of ways," Rosberg said. "As a team we made all the right calls in a difficult qualifying session and the balance of the car felt very strong until unfortunately I was forced to retire.

"It was a real shame, but with the new regulations we are always going to be pushing the boundaries and I know how hard the team is pushing to give us the best car out there every weekend. I lost a lot of points and the Championship battle is very close, but I'm feeling good.

"From the test last week we're straight into the next race and another chance to regain the momentum, which is of course my target. Hockenheim is a crucial race for all of us. It's the home Grand Prix for Mercedes-Benz and a second home race for me after Monaco, so I'm really focused on getting a top result this weekend. It's actually the circuit I've won the most races at during my career through all the junior categories, so I know it suits my driving style."
