SEAT will be the first Manufacturer to run diesel-powered cars in the FIA World Touring Car Championship. Next week in Anderstorp Jordi Gené and Yvan Muller will drive two León TDI machines equipped with a 280 hp turbo-diesel engine. This will be a milestone for both SEAT and the FIA as it is the first time diesel cars line up at an FIA World Championship race. Jaime Puig, Director of SEAT Sport, explained: ''''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 León TDI can become competitive in the mid and long term.'''' Chief Engineer Benoît Bagur said: ''''The basis for the engine is the 170 hp 2.0 of the León FR. We kept the engine block and cylinder head of the production model, but changed the turbo charger and gearbox. We had to alter the front part to house the intercooler and create new air intakes. The diesel engine is 35 kilos heavier than the petrol engine, so we had to redistribute some weight.''''
