What’s new for WRC in 2022?

This year represents the introduction of new Rally1 regulations designed to move the WRC into a much more sustainable future and to attract new manufacturers.

They have resulted in Hyundai (i20 N), Toyota (GR Yaris) and M-Sport Ford (Puma Rally1) designing and building all-new cars around a new safer, steel spaceframe chassis.

The biggest change to the cars is the introduction of a mandatory 100kW hybrid unit coupled to the 1.6-litre turbocharged internal combustion engine, the only key component carried over from the previous generation of cars. In tandem, this will allow the powertrain to develop 500bhp to be used in short bursts across every stage.

Cars will be up 70kg heavier than their predecessors, this is mainly due to the addition of the hybrid system. In total, Rally1 machines will weigh in at approximately 1260kg.

The new regulations have effectively abolished extra aerodynamic devices such as wings and flicks being added to the bodywork outside of the front splitter and rear wing. The overall downforce created and its effect on the car has been reduced by approximately 15% compared to the previous generation of vehicle.

Trick centre differentials used to fine tune handling are now banned in favour of a simpler front and rear mechanical limited-slip differentials offering a fixed 50:50 toque split between the front and rear wheels. Suspension travel has been reduced to 270mm.
