How World RX’s electric future will work

Combustion-engined and electric cars will race together in 2021


World Rallycross this week confirmed more details of its plans for an electrified future, which will include a combined combustion and electric top level championship in 2021.

Starting this year the all-electric Projekt E support category will be on the bill at five of the World Championship’s nine European events, while the RX2, European Supercars, and European S1600 categories will also feature.

Full kits from STARD are being provided for Projekt E at a cost of €194,000, while drivetrains from road-going electric cars can also be used. A STARD-provided motor controller will be used to level the playing field.

Beginning in 2021, the one-make RX2 series will be phased out in favour of a new low-cost FIA ERallycross category. European Supercars, and European S1600 will again feature on the combustion engined side of the spectrum.


Projekt E will debut this year

However, in the World Championship, new electric Supercars will be allowed to race in the top category for the first time, with them being allowed to compete alongside more traditional Supercars ahead of a planned full adoption of electric rules for the category in the future.

Electric drivetrain specialists Kreisel are developing a new powertrain for electric supercars that can either be fitted to existing Supercar chassis in place of the standard four-cylinder petrol setup. Alternatively it can be used in purpose-built new electric supercars.

The four-motor setup will deliver around 680 bhp, making it approximately 13 percent more powerful than the current breed of rallycross supercars. The drivetrain will cost €300,000, plus another €100,000 for three years of factory support.

ERallycross meanwhile will use spaceframe cars developed by QEV Technologies of Spain, with a four-wheel-drive electric drivetrain delivering around 335 bhp, putting it on par with the Olsbergs MSE Supercar Lite currently used in RX2.


RX2 is expected to be sidelined in favour of a second all-electric support class
