The cars eligible for the WTCC are, in principle, "Super 2000"
specification cars that follow the FIA's regulations for the category.
Super 2000 cars must be based on production cars of which more that 2500
units are built within twelve months consecutive. For the purpose of lower
costs, only a limited scope of modification are allowed, but it is generally
welcomed by the manufacturers and is one of the major factors for the WTCC's
success.
For the 2008 season, five marque brands, BMW, SEAT, Chevrolet, Honda and
Lada, are registered for the manufacturer's title contention.
