Brazil preview quotes: Toyota

"I enjoy racing at Interlagos but it is a very demanding circuit. For the drivers it is a challenge because of the bumps, but from a technical side it is interesting as it is important to have mechanical grip in the tight infield, particularly from turn 8 to turn 11, but there is also a long flat-out section through the final corners and onto the main straight. We will work hard to find the best set-up to deal with this, as well as the bumps, when practice starts on Friday. After two troubled races in Japan and China, I hope we can bounce back in Brazil."

Jarno Trulli: "I enjoy the challenge of racing at Interlagos so I am looking forward to this race. It is one of the trickiest tracks in Formula One, with an enjoyable mix of high and low speed corners. But there are other factors as well to consider, for example the track is anti-clockwise so it puts extra strain on your neck, although I have trained for this so it will not be a problem. And then there are the bumps, which make life difficult with set-up, particularly on a Friday.

"It's been a really hard few races for me and the team so I am keen to end the season with an improved result before we focus all our energies on 2008. We have the potential to score points but we have to push hard and not make any mistakes."

Pascal Vasselon - Senior General Manager Chassis: "We enjoy going to Interlagos because in Brazil there just seems to be more fans than virtually anywhere else - they have a true passion for motorsport. The circuit itself is unique in that it is probably the only track where suspension settings are so important.

"Normally the main performance factors on an F1 car are aerodynamics and tyre usage. At Interlagos it is still about tyre usage but suspension settings are clearly a major performance factor due to the bumpy nature of the track. You have to find a way to keep your wheels on the ground and so set-up parameters that are secondary everywhere else become key in Brazil.

"An interesting thing about going to Sao Paulo in 2007 is the tyre choice. Bridgestone has proposed the two softest compounds - the Monaco compounds. But in terms of tyre severity, Interlagos is much harder than Monaco so one of the challenges will be tyre management and we expect the track to be tough on the softer tyre in particular."
