FIA World Rallycross Championship
The FIA World Rallycross Championship (official abbreviation World RX or WRX) is a rallycross series organised and promoted by the FIA. In September 2025, just days before the final round of the 2025 season, it was announced that the championship will revert to being the European Rallycross Championship as seen prior to 2014.
The series currently consists of 12 two-day events driven on closed circuits with mixed surface (mostly asphalt and gravel). Each event consists of:
During the first FIA World Rallycross Championship season in 2014, two classes were run, Supercar (later RX1) and the supporting RX Lites series (later RX2). RX Lites teams raced identical cars prepared by OlsbergsMSE. The World RX Championship series was introduced to distinguish it from the FIA European Rallycross Championship, which has been contested since 1976 and was renamed in March 2013.
An electric category was planned to be introduced in 2020, but it was announced in August 2018 that the introduction of a fully electric Championship would be delayed until 2021 to allow manufacturers more time to submit an interest to join following the rules change. Instead, the Projekt E class was run in 2020 as a special parallel series using a spec racer. The Projekt E spec electric rallycross car was revealed in September 2019 at the Riga Motor Museum in Latvia. FIA announced in August 2020 that RX2e would be replacing the RX2 category for the 2021 season. The top World Rallycross Championship series switched to electric cars (RX1e) in August 2022, making World RX an all-electric race series. In 2024, ICE cars were reintroduced into the top level World Rallycross Championship to race alongside the electric RX1e vehicles.
From 2025, there is one World Rallycross Championship and two European Rallycross Championships:
The RX2e class was discontinued after the 2024 season.
The top-level RX1 Supercars division use 2.0 L, turbocharged, four-cylinder engines, which produce approximately 570–600 hp (430–450 kW), and between 620–680 lb⋅ft (840–920 N⋅m) of torque, while using a 45 mm (1.8 in) intake restrictor. The engines run 50 psi (3.4 bar) of boost pressure, and completely unrestricted, are capable of making about 1,000 hp (750 kW) and 1,100 lb⋅ft (1,500 N⋅m) of torque. They are four-wheel-drive, and use a Sadev 6-speed sequential gearbox. They use launch control, and are capable of accelerating from 0–60 mph (0–97 km/h) in under 2 seconds; which is faster than a Formula One car. Fully prepared, the cars weigh about 1,300 kg (2,900 lb), including the driver, and with oil and fuel.
The second-tier RX2 Supercar Lites division uses a 16-valve, 2.4 L, naturally aspirated, Ford Duratec inline-four engine, making between 310–320 hp (230–240 kW) and 300 N⋅m (220 lbf⋅ft) of torque. They are also four-wheel-drive, and also use a 6-speed sequential gearbox. They have a minimum weight of 1,100 kg (2,400 lb), including the driver.
