US preview quotes: Williams

"I think we can be quite strong in Indianapolis, providing we make the right decisions in our preparations. I like racing in the US, even if the Speedway was not designed for Formula One cars, and I respect the history of the track. It's important that we come home with some points from these two flyaways."

Nico Rosberg: "Again, Indy is a track I haven't yet raced at but one which I've learnt on the simulator. It seems to be quite different from the other circuits due to the very long straight and the banking. It will be interesting to see what Michelin and Bridgestone will come up with after what happened last year.

"I really hope that the fans will come back this year because I have watched several Indy 500 races on the TV and the atmosphere is just great with all those huge grandstands packed with people! For a driver, the bigger the crowd, the better it is!"

Sam Michael, Technical Director: "Indianapolis is a unique circuit, one which has a slow speed infield section followed by a long straight that goes through the oval, with around 23 seconds of full throttle time. It is an interesting proposition for the drivers and the engineers because most of the lap requires maximum downforce while, for the straight, you want to run as little wing as possible.

"Minimising drag on this section will be important. We have analysed all the data from the last Grand Prix to ensure that we have a strong tyre choice with Bridgestone and we will take well tested and proven constructions to cope with the aggressive surface on the banking.

"Car specification for Indy will remain similar to that which we ran in Montreal as the downforce levels at both circuits are fairly similar to each other. Set-up will also be similar as both tracks are dominated by slow speed corners and fast straights."

Simon Corbyn, Head of F1 Race Engineering, Cosworth: "The Formula One circuit at Indianapolis is a combination of the longest straight on the calendar and a tight infield section. It is therefore a demanding track for engine performance and reliability, while it's also challenging in terms of optimising the engine control systems. Both CA2006 Series 4 engines will carry over to their second race events at the US Grand Prix.

"Nico's engine did not suffer any damage from the accident in Canada so it will be a strong second event engine. Cosworth are proud to have a long history of success racing at the Brickyard. Let's see if we can add to it this weekend with WilliamsF1."
