WSC, the TCR rights holder, has published the initial Balance of Performance [BoP] list for the 2019 season, with the list featuring 23 models and including the five new cars recently tested in Valencia.
The BoP will be applied to all TCR-certified races and series around the world, and considers the performance of each different model of car.
In order to balance performance, the following parameters are varied: engine power level, target racing weight, compensation weight, BoP ballast, total minimum racing weight and the ride height.
The all-new Hyundai Veloster N, currently racing in North America, has the least favourable BoP parameters in two areas, with the car running at 97.5% power, with the most BoP weight at 40 kg and the joint-highest ride height, at 90 mm.
The Hyundai i30 N also runs with 90 mm ride height and 97.5% power, but benefits against its sister model by running with just 10 kg of BoP weight.
The new Lynk & Co 03 TCR, being raced by Cyan Racing in the FIA World Touring Car Cup, has emerged with a 97.5% power limit, 80 mm ride height and 30 kg of BoP weight.
The most favourable parameters are handed to the Peugeot 308 Racing Cup, a car not specifically built to TCR regulations but rather adapted to them, with 102.5% power, 70 mm ride height and a -60 kg BoP weight.
Compensation weight is fixed at 60 kg for the start of the season but may be adjusted according to the results of each model of car in the various TCR series worldwide. This parameter is essentially unrelated to the measurable performance of the car but is dictated by race results on the whole.
