Singapore GP: Williams preview quotes

Valtteri Bottas: "I've never driven at Singapore in a lower category and it was one of the tracks that I didn't drive in Friday practice last year for Williams so this will be a new challenge that I'm really looking forward too. I will be doing a lot of simulator work ahead of the grand prix to get used to the layout because it has a lot of corners that come in quick succession. I'm normally quite fast at learning new tracks though and showed in Montreal this year that I can quickly get up to speed. The fact that the race takes places at night creates a unique atmosphere but I will try and keep my routine the same as it is important to maintain a rhythm between races, and for that reason I will be staying on European time throughout the week. One thing I do change is the transparency of my visor as we have to use an anti light glare instead of a sun protector because the lights lining the circuit are very bright."

Xevi Pujolar, chief race engineer: "The Singapore night race is a unique event that we all look forward to despite the fact that it is probably the most demanding circuit of the year for both driver and car. It is mentally and physically draining for the drivers as it's not only one of the longest races of the year, but they also have to cope with the high temperatures and humidity with the 23 corner layout offering almost no rest. Despite being run at night under floodlights the temperature still averages 30°C, with a humidity of around 75 per cent. There has been a modification to the track layout for this year, the chicane at Turn 10 has been removed and replaced with a flowing left-hand corner before the acceleration zone towards the Anderson Bridge. Singapore has the highest pitlane speed loss of the season and a high chance of a safety car - there hasn't been a race in the modern era without at least one safety car being deployed. These factors, added with how difficult it is to overtake, all hamper strategic capability and for the last couple of years it has typically been a three-stop race. However, Pirelli have gone one step harder on the prime tyre bringing the medium compound so this may change this season."
