 All TCR cars have a common forefather; the SEAT León Cup Racer racing car which was introduced as successor to the SEAT León Supercopa used in several successful single-make series.The 2.0L engine formula was derived from this car, as well as the standardised front splitter and rear wing.Initially, the specification and accompanying international series was known as TC3, to indicate its intended position at the entry-level end of the touring car pyramid.
