Chinese GP preview quotes: Williams

Valtteri Bottas: I have experience driving the Shanghai International Circuit as I drove in FP1 last year and it's a track that shares similar characteristics to the last Grand Prix in Malaysia. Whilst not as hot and humid, the weather can be variable so you need a car that works well in different conditions. Getting the tyres to work will be the biggest challenge facing all of the teams, as the temperatures are often low and the smooth track surface is quite different to what we saw in the first two races. I was unlucky not to score my first points in the last race and whilst we aren't quite where we feel we should be, the team has been working hard to understand the car and bring a package to this race that's a step forward in performance.

Mike Coughlan, Technical Director: After a difficult two races we've been back at the factory going through the data to try to understand where we need to improve. We feel we have a better understanding of where we are and the whole team has been working hard to improve our competitiveness going into the next few races. Ultimately we are looking at a significant upgrade for the Spanish Grand Prix.

The ambient conditions in China will be kinder although the weather can be quite changeable. The cooler temperatures we expect are not only more favourable for the car but also for both the team and driver. The circuit is also usually quite hard on tyres, so that could prove another challenge.
