Germany Friday quotes: McLaren

"The accident took all four corners off the car, so I was a little bit upset with myself. The guys work so hard during the week to get the car ready, and then you get to the track, do a few laps, and total the car, which isn't great. It was a huge amount of work for the guys, too, but they've just been phenomenal.

"It was positive to get back out there and overcome the difficulties I had in the morning. We missed the afternoon's rain too, which was good. Now I have a decent idea of where the car is, so hopefully we can make some positive set-up changes overnight.

"The new blown diffuser still isn't perfect - it's not something you can just put on the car and drive with the same balance that you had before; you've got to alter the balance, and modify your driving style. We're still working on it, but there's potential there."

Jenson Button - 15th: "This morning was useful, because there's a possibility of more rain tomorrow. But we didn't have a very good set-up for P1 in the wet - we changed the car over lunch, and I was much happier with the balance this afternoon.

"As always, we have to do things to make the car better. The long-run pace is pretty reasonable - I think we were expecting more issues with graining on the Option, but it didn't seem to be a big issue. Hopefully, tomorrow's morning session will be dry so we can focus on some useful set-up work.

"Obviously, Lewis had a problem this morning, so I had a busy afternoon running through our long-run programme in P2.The new floor appears to be working well. We still need to look at the data to see how much of an improvement it's giving us, but there's no negative to it, which is great."

Martin Whitmarsh - Team principal, Vodafone McLaren Mercedes: "Today's two sessions presented difficult and changeable conditions in which to conduct the necessary tests, but we nonetheless gathered a lot of useful data that will hopefully give us good direction throughout the rest of the weekend.

"Clearly, Lewis's small error this morning caused damage to his car that took a while to repair, thereby limiting his running this afternoon. In the end he went out with just 13 minutes left, and did just one run on the Prime tyre. Nonetheless, he posted the seventh-fastest lap of the session and remains well placed to do a solid job tomorrow.

"This afternoon Jenson knuckled down to a disciplined programme of long running on heavy fuel loads, concentrating on race durability.

"We feel we have decent pace here - and, as I say, having concentrated largely on long running on heavy fuel loads today, will focus on qualifying practice tomorrow morning."
