A TCR Touring Car is a touring car specification, first introduced in 2014 and 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. 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 to Balance of Performance (or BoP) adjustments to ensure close racing between different vehicles. From Wikipedia
