Suspension travel has been reduced to 270mm. ![]() 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. The overall downforce created and its effect on the car has been reduced by approximately 15% compared to the previous generation of vehicle. 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.

Heavier carsĬars will be up 70kg heavier than their predecessors, this is mainly due to the addition of the hybrid system. Hyundai’s Thierry Neuville has already hailed the new safer chassis for allowing him to walk away from a nasty testing crash in December. A frontal impact against a rigid obstruction resulted in 70% less intrusion in the bulkhead area, protecting the crews feet and legs. The roof section can absorb energy up to 115% better than a previous WRC body shell reinforced by a traditional roll cage. New tougher and safer steel space frame chassis, regulated by the FIA, form the base of the car, built to a minimum wheelbase for the first time.Īccording to the FIA’s tests and research, side impacts showed a 51% reduction in intrusion. The chassis is no longer built around the production road car with teams constructing their machines from scratch. The cars will also be powered by a 100% sustainable fuel. The hybrid unit can withstand an impact of 70G. In full electric mode the car has a range of 20km, while its 3.9KWH battery, operating up to 750 volts, can be plugged in and recharged in the service park within 30 minutes.
