Just like Audi presented the R10 TDI –the world's first
Despite facing a double handicap with the diesel car since, according to regulations, a diesel-powered car has to weigh 30 kg – 66 lb more than one with a petrol engine along with the fact that the intercooler and the turbo are situated ahead of the front axle, thus distorting even weight distribution, the Seat team has faith in the project. After seeing what Audi accomplished with the R10 TDI, who can blame them. -Continued: Click “Read More…” below
Jaime Puig, Director of SEAT Sport: ‘The regulations allow us to register a car equipped with a diesel engine, and we were happy to rise to the challenge. We are satisfied with the testing results and believe the Leon TDI WTCC can become a competitive car in the mid to long term. For the moment it will only be driven by Jordi Gené, who has been responsible for its development, and Yvan Muller. Gabriele Tarquini, Tiago Monteiro and Michel Jourdain will continue to drive the usual model.’
Benoit Bagur, SEAT Sport Chief Engineer: ‘Since the FIA made it possible to enter a diesel engine in the competition, we started looking into the viability of the project, and it took off a few months ago. The basis for the engine is the 170 PS 2.0-litre mounted in the Leon FR. We kept the engine block and the cylinder head of the production model, but changed the turbo compressor and gearbox. Furthermore, we had to alter the front part to house the intercooler and create new air intakes. The diesel engine is 35 kg heavier than the petrol, so we had to redistribute some weight. After satisfactory test results, we are eager to see its potential in actual racing conditions.’
Jordi Gené, SEAT driver: ‘We have been working on this project for several months, and appreciate its great potential. I am looking forward to it because one of the aspects I most like about my job is the possibility of working on new car development, and even more so when they feature new technology. We are facing a double handicap with the diesel car. The first is that according to regulations, a diesel car has to weigh 30 kg more than one with a petrol engine. The second is that the intercooler and the turbo are situated ahead of the front axle, which makes weight distribution detrimental compared with a petrol car. But, as the Leon has the best chassis in the Championship and our engine torque will be much higher, I think that, in the mid-term and on certain tracks, we can be competitive.’
Yvan Muller, SEAT driver: ‘I have done some testing with the diesel engine, and the lap times are very similar to the petrol. It is a little slower in the corners because of the extra weight and there is more stress on the tyres, but it is a little bit quicker on the straights. The chassis of the SEAT
