The FIA World Touring Car Cup (abbreviated to WTCR, referring to the use of TCR regulations) is an international touring car championship promoted by Eurosport Events and sanctioned by the Fédération Internationale de l'Automobile (FIA). It has had different incarnation of a World Touring Car Cup held between 1993 and 1995. Following the 2017 season, an agreement was reached for the World Touring Car Championship to become WTCR and use the TCR technical regulations. With titles for drivers and teams only, the WTCR series changed to 'World Cup' rather than 'World Championship' status in 2018.
In 1993, with the high popularity of the Super Touring category, the FIA hosted the FIA Touring Car World Cup — an annual event for touring car drivers hailing from national championships all over the world. The 1993 race at Monza was won by New Zealand's Paul Radisich, at the wheel of a Ford Mondeo ahead of Nicola Larini's Alfa Romeo 155, with no manufacturer title awarded. The race was run for two more years, (won by Paul Radisich again in 1994 at Donington Park in a Ford Mondeo, manufacturer title went to BMW, and Frank Biela in 1995 at Paul Ricard in an Audi A4 Quattro, and manufacturer title went to Audi). A similar event was planned for 1996 at the A1 Ring, Austria, but was cancelled due to a low number of provisional entries (10 cars). It was never brought back thereafter.
On 6 December 2017, during the FIA's World Motorsport Council in Paris, it was approved the formation of the new World Touring Car Cup starting from 2018. The new series would utilize the TCR rules, which have been in use in numerous national and international touring car racing series, including the TCR International Series. As a result of the formation of the WTCR, both the WTCC in its current format and the TCR International Series would be discontinued immediately.
A new format was introduced, with one qualifying session and one race on the first day and a three-phase qualifying session on the second day and two races, with the first one having the top 10 of the grid reversed.
Cars have to be production models, with a minimum production of 5000 samples in a year.
The engine is limited to a displacement of up to 2 liters, turbo charged, and with the aid of restrictors, to a maximum yield of 350 Hp.
Each car is assigned a minimum racing weight which is used to balance the performances.
