Japanese Grand Prix: Williams preview quotes

Bruno Senna: I'm really looking forward to the Japanese Grand Prix. It's one of my favourite tracks of the season andit's very fast and flowing but quite narrow compared to some of the other circuits we visit. It feels amazingly quick and is one of the biggest challenges as a driver. It is similar to Spa-Francorchamps so it's a real drivers' track. You can get variable weather in Japan ranging from warm and sunny to rain that stops qualifying. It's always exciting though and we have a good potential to be strong there.

Mark Gillan, Chief Operations Engineer: Suzuka is a fantastic old-style track with its trademark figure-of-eight layout that proves a tough technical test for the drivers. The circuit layout leads to very high average cornering speeds and energy input into the tyres, but it's reasonably light on the brakes. Following Singapore we have been working hard to ensure that the cars run as reliably as possible for the remaining races. Given the excellent pace shown at Singapore in both qualifying and the race, we expect to be strong in Suzuka and will bring further updates as part of our continuous improvement process.

Remi Taffin, Head of Renault Sport F1 Track Operations: The power sensitivity at Suzuka is not higher than say Canada or Valencia, but the variety of corners over the lap requires some careful preparation. The first half of the circuit, from the First Curve to Spoon Curve, is flowing so the engine needs to be responsive and smooth throughout the power curve. The second half of the track, from the exit of Spoon to the end of the pit straight, is all about outright power as 90% of this section is spent at full throttle. We will most likely introduce new engines here for this reason.
