The 2022 WRC season is about to commence, with all new specification Rally1 machinery, featuring tube frame chassis and a hybrid powertrain, and M-Sport has provided an explainer on the hybrid architecture and how its energy will be deployed in rally conditions.
While the cars’ engines are largely unchanged under the new rules, they will now be augmented by a spec hybrid system, supplied by Compact Dynamics, which consists of a battery, inverter and motor, all housed in a single, centrally mounted unit.
With an all-up weight of 100kg (once fluids are added) the hybrid unit can provide a 100kW boost on top of the IC engine output (134bhp) taking overall power output around 500bhp. Energy deployment will be governed by pre-set maps, and recuperation under braking is limited to 30kW. On road sections between special stages, the system will allow for a fully electric range of around 20km.
PMW will be providing in-depth reporting on the WRC’s new era once stages are underway in Monte Carlo from January 20.
