The results of the TCR Balance of Performance test, which took place at Valencia last month, have been published, with the minimum weights for all cars reduced by 20 kg and the Audi emerging as the heaviest car.

In addition to the base weight being lowered for all cars, there will be a further reduction for those running the DSG gearbox, meaning that the sequential cars will run at a weight of 1,265 kg with the driver on board, and the DSG cars at 1,230 kg with the driver.

The TCR technical department also confirmed that the BoP this year is based on engine performance, ballast and ride height. All cars will run with an 80 mm ride height.

Certain cars will be permitted to run at 102.5% of engine performance, including the Alfa Romeo Giulietta TCR, the Peugeot 308 TCR and the DSG versions of the CUPRA, Audi RS3 LMS, SEAT León and Volkswagen Golf GTI.

The full BoP weights for 2018 are:

-30kg: LADA Vesta TCR, Peugeot 308 Racing Cup, Renault Mégane TCR

-20kg: AR Giulietta, Honda Civic FK2 and FK7 cars, KIA c’eed, Peugeot 308 TCR

-10kg: Cupra TCR, SEAT León TCR SEQ, Opel Astra TCR

0kg: Hyundai i30 N TCR, Volkswagen Golf GTI TCR SEQ, all DSG cars

+10kg: Audi RS3 LMS SEQ

Cars will be limited to 340 bhp (-2.9% compared to 2017) with a torque limited to 410 nM (-2.4%) after meetings were held with the manufacturers’ technical representatives.

The BoP will be applied immediately, starting with the first race of the new FIA World Touring Car Cup (WTCR) in Morocco this weekend, where all cars will also carry 60 kg of additional compensation weight.

After the BoP, the final running weights for the cars in WTCR are thus:
