Toyota duo bemoan lack of grip

Schumacher endured another difficult day at Indianapolis, finishing down in 20th position after claiming the track was very slippery throughout the sessions.

"It was a pretty difficult session for us," admitted Schumacher. "It was very slippery out there and there was not a lot of grip. That was partly down to the track conditions and they did improve as the day went on.

"It's difficult to tell where we really are because it's only Friday. Still we have some work to do overnight.

"We tried several different options with our set-up and now we have to look at the results from today so we can get the maximum from the car in qualifying and the race.

"It was positive to get through both sessions without any problems with the car because we were able to make good use of the three hours of track time. We are working hard for tomorrow and I am looking forward to it."

Trulli complained about the same issues with the grip, the Italian posting the 17th fastest time.

"That was a difficult session for me today," said Trulli. "I found the car quite difficult because there was very low grip in general, as usual here at Indianapolis.

"We did quite a lot of laps and we tried out different options, as well as both kinds of tyres, but we have to work hard now to find a bit more speed in the car before qualifying and the race.

"It was positive we did not have any mechanical problems on the car today and we were able to do all the work we planned. I've always had very good races here at Indianapolis so we will now try to get the best out of the car for qualifying and get another good result."
