Canada preview quotes: Williams

Bruno Senna: Canada is one of the most challenging tracks of the season. It is a combination of a street circuit and a normal fixed circuit with a mixture of very fast, long straights and tight slow corners with heavy braking. It is also important to have as much track time as possible before the weekend to learn the track surface because it can evolve quickly. Our car is looking competitive at this stage of the season so hopefully we can show good pace here.

Mark Gillan, Chief Operations Engineer: On the back of a mixed weekend in Monaco the whole team is looking to demonstrate further improvement in Montreal, with the aim of getting both cars home in the points. Montreal is a great race and usually full of drama with a very low pit lane loss which pushes the strategy towards having more stops. The high likelihood of a safety car deployment adds to this drama. The track layout is very hard on brakes and one must also ensure that the aerodynamic package has an appropriately high efficiency target. Pirelli bring to Montreal the same tyre compounds used in Monaco, namely the soft and super soft tyres. Weather wise we are expecting ambient temperatures into the high 20Cs with corresponding track temperatures in the high 30Cs, although there is a chance of rain throughout running.

Rémi Taffin, Head of Renault Sport F1 Track Operations: Canada is a completely different track to Monaco and also unique in itself. The long straights demand good top end power but the heavy braking zones of the hairpin and chicane need effective engine braking and good pick up on the exit, so it's rightly called an 'engine breaker' because the engine doesn't get any respite at all. The challenge is to find the right balance between delivering maximum performance and maintaining 100% reliability, just like at Spa and Monza where the risks have to justify the gains.
