Canada preview quotes: Williams

"The circuit requires a completely different aerodynamic package to the ones we've used for the first part of the season, which means a low to medium downforce level to help our top speeds. It also means we could see a slight change in performance from some teams as it's a fresh opportunity to find pace, I'm certainly hoping it'll provide us with a chance to improve our performance in the right direction.

"Traditionally, Montreal is heavy on brakes and that's why we were testing in Monza last week. It's also a circuit which rewards good horsepower from the engine, so that should be a positive for us. We certainly need both Williams' in the points at Montreal."

Nico Rosberg: "I'm really looking forward to the Canadian Grand Prix for two big reasons. Firstly, we had a good test in Monza last week running the low to medium downforce set-up so everything is in order for the Montreal track. We should be stronger there than we were at Silverstone and we have the potential to score some points.

"The second reason is that everybody keeps telling me that the Canadian Grand Prix is one of the nicest races of the season. It will be my first time there and, although that makes it a greater challenge, I'm looking forward to getting everything out of it that I can."

Sam Michael, Technical Director: "Montreal is a low drag circuit, more so now with the v8s, and is made up of long straights, a lot of slow corners and chicanes. There are two or three good overtaking opportunities every lap which always makes for good racing at this circuit. Traditionally hard on brakes and temperatures, the window will shift slightly this year following the reduction in power levels and the increase in tyre grip compared to last season.

"We have a full car upgrade for Canada in the shape of front and rear wings, winglets, nose and diffuser revisions which were all tested and successfully signed off at the Monza test. Strategy at Montreal is always interesting and this year will be no exception."

Simon Corbyn, Head of F1 Race Engineering, Cosworth: "Cosworth will install two fresh CA2006 Series 4 engines for the Canadian Grand Prix, as scheduled. Results from last week's Monza test are directly relevant to Montreal and this data will now be used to define the engine control system calibrations for the event.

"Montreal features notoriously tough braking events and so we'll be working closely with Williams to optimise the engine braking settings for this circuit."
