Seat Leon WTCC
SEAT introduced the second generation León into the World Touring Car Championship (WTCC) to replace the Toledo Cupra which it had raced in the early rounds of the title. The car features several modifications, including a racing engine that develops over 256 bhp, a Hewland sequential-shift gearbox, and an aerodynamic package for increased downforce (with its hatchback shape, the León is disadvantaged against conventional three-box saloons). Minimum weight is 1,140 kilograms (2,513.3 lb) with driver. SEAT Sport, in partnership with Oreca, runs six cars in the WTCC. Two other cars are run by SEAT Sport UK (Northern South) based in Northampton, UK in the British Touring Car Championship (BTCC). A further two cars are run by SEAT Sport Italia in the Italia Superturismo Championship.
In 2006, the Supercopa León was replaced by the new shape León. The car is potentially faster than the WTCC version, as it features a turbocharged 2.0 litre engine, with over 296 bhp, increased torque, the DSG gearbox, better aerodynamics (it includes the WTCC car's front and rear spoilers, plus a venturi tunnel under the car, instead of a flat bottom), and 18 inch wheels, instead of the mandatory 17 inch wheels from the WTCC.
