Spain Friday quotes: Toyota

Timo Glock - 18th: "It was not a very good day for me today to be honest. I was struggling quite a bit with the tyre behaviour in both practice sessions and it is really tricky to understand what the problem was. We have to analyse the results from today and work hard to make an improvement for qualifying tomorrow. I'm not happy with how things have gone today but we won't give up; we will do our best to find a solution."

Dieter Gass, Chief Engineer Race and Test: "Even though I am not too worried about the timing sheets, we have to say it was hard work today. Thanks to an enormous effort from everyone in Cologne, we brought quite a significant aero update for this weekend and with no in-season testing, we had to evaluate it all today. We did a lot of laps and made several comparison runs to get as much information as possible.

"Obviously you don't have as much time to concentrate on these parts as you do in testing so that makes it quite difficult. As well as evaluating the upgrades, we did quite a lot of tests, mainly on aero, brakes and tyres. We got some interesting results which we will analyse tonight and try to find the best compromise for tomorrow."
