 In 2015 the FIA designated the TCN-2 nomenclature to the TCR regulations.This allowed the TCR-spec cars to compete in the Super 2000 class (later renamed ETCC-1) of the European Touring Car Cup alongside the older TC2 and TC2T cars previously used by the World Touring Car Championship.From the 2017 season ETCC began using the TCR technical rules instead of the FIA's TCN-2 ones.
