US Preview Quotes: Red Bull

Christian Klien: "There are always a lot of spectators in America and the event has a good atmosphere, so on that side of things it's a good race. In terms of the circuit, it's not the most exciting in the Championship. There's a long straight where you go flat out for about 20 seconds, but the infield is very slow. It's not such a technical track and there aren't really any corners that stick out in my mind. But I enjoyed being there last year, although I didn't finish the race. I had a crash at the first corner, so I certainly hope to do better this year. It's hard to set definite aims in terms of finishing and grid positions, but I'll be looking to do a good job for the team and for myself."

Scott Speed (Friday Test Driver): "My main focus for Indianapolis will be to gain more time in the car, to learn as quickly as possible and fulfil my job for the team. I think the time I spent in the car in Montreal almost doubled the total time I'd ever spent at the wheel of an F1 car. At the moment, it's all about getting used to the car's set-up, as it's so different to anything else I've driven. The main difference is the amount of aero- performance, as the F1 car is far more sensitive. Competing in the GP2 series on grooved tyres has helped me with my main job for the team, which is providing feedback to help them assess the different tyres. A lot of people think there might be some pressure on me, but the amount of pressure I put on myself outweighs anything else that the situation creates - I just concentrate on the job in hand. I'm flying to Nice after Canada to complete a GP2 test, before flying to Indianapolis for Friday's Free Practice session. To drive an F1 car in my home country will be such a thrill, I can't wait to get back in the driving seat."

Christian Horner, Sporting Director: "Indianapolis is a circuit steeped in tradition, which usually provides exciting racing, mainly as a result of the overtaking opportunities provided by a fast right hander onto the straight and the tight Turn 1 which is a classic passing point. While the circuit might not be that interesting for the drivers, with an infield that's a bit like a go-kart track, it produces good races. F1 seems to be gaining US fans all the time and it's good for the sport to have up and coming American driver, Scott Speed, representing us in Friday's Free Practice session."

Guenter Steiner, Technical Director: "In Indianapolis, the set-up of the car is a compromise between finding high-speed on the flat out straight, while enabling the driver to attack through the slower infield section. It's all down to the aerodynamic set-up and we'll be analysing the car to see how it will work best for the race. There are two possible strategies for Indianapolis. One option is to set up the car with high down force so it's quick on the infield, but slower on the high-speed section, while the other is to set the car up with less wing so it's faster on the high speed straight, but requires the driver to cope with deficiencies through the in-field section. As planned at the start of the year, we will be introducing an engine upgrade at this event - the Cosworth Series 12 engine. We've completed two engine development track tests, as well as lots of dyno endurance testing, so it's looking good for the race."

Simon Corbyn, Head of Cosworth F1 Race Engineering: "The introduction of the TJ2005 Series 12 engine at the Indianapolis GP represents a tremendous achievement for Cosworth. This upgrade is a further step along a two-year development programme to deliver the benchmark F1 engine. The engine has been delivered on schedule and has achieved its performance and reliability targets. In qualifying for Indy GP we will have an increase of 30BHP & 700RPM - these represent the biggest gains Cosworth have ever achieved on a mid-season upgrade. Hopefully the Series 12 will allow Red Bull to build on the excellent results already achieved this season with the Cosworth TJ2005 engine."
