ATCR Touring Car is atouring car specification first introduced in 2014; it is now employed by a multitude of series worldwide. All TCR Touring Cars are front wheel drive cars based on 4- or 5-door production vehicles, and are powered by 1.75 to 2.0 litre turbocharged engines.[1] While the bodyshell and suspension layout of the production vehicle is retained in a TCR car, and many models use a production gearbox, certain accommodations are made for the stresses of the racetrack including upgraded brakes and aerodynamics. Competition vehicles are subject tobalance of performance (BoP) adjustments to ensure close racing between different vehicles.
The project to develop the TCR specification was spearheaded by formerWorld Touring Car Championship manager Marcello Lotti. All TCR cars have a common forefather; theSEAT León Cup Racer racing car which was introduced as successor to theSEAT 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 andrear wing.[2] Initially, the specification and accompanyinginternational series was known as TC3, to indicate its intended position at the entry-level end of the touring car pyramid. However, upon being approved by the FIA in December 2014, the specification was renamed TCR.[3]
The FIA licensed the TCR regulations under the name of WTCR for usage in theWorld Touring Car Cup. The specification is identical, however it is frozen until the end of 2019, and cars are required to obtain an FIA passport after going through TCR homologation.
Since 2017, TCR organisers World Sporting Consulting (WSC) have awarded the TCR Model of the Year award for the most successful TCR car across a year.[5] The title is awarded on the basis of a points system that gives points to all the different TCR-certified cars competing in all the TCR-sanctioned races of the year.[6] The points are adjusted by coefficients that take into account the level of the competition, the number of cars participating and the number of manufacturers represented.[6]
