WRC supports series to follow hybrid route in 2023

Must read

Cars from the FIA World Rally Championship’s WRC 2 and WRC 3 support categories will follow their big brothers into rallying’s all-new hybrid era in 2023.

The FIA confirmed the move earlier this month, outlining a milder hybrid derivative than the Compact Dynamics-sourced hardware bound for headline category cars in 2022.

Rally2 specification cars will run a 48-volt low-voltage starter/generator system generating approximately 10bhp.

The FIA said: “As well as lowering emissions, the clear objective is to demonstrate how existing road-car technology can be transferred into the motorsport arena, rather than the bespoke plug-in hybrid performance-orientated system that is being developed for Rally1.

“A set of regulations is currently being discussed by the FIA Technical Department with the aim of controlling costs and managing potential performance differentials between the different ‘off-the-shelf’ hybrid systems that will be utilised.

“Cost management will remain a key focus with cost caps for specific parts, which has proven to be an effective tool in rally. The target is to have regulations ready for approval in September 2021 and it is proposed that the new-generation Rally2 hybrid cars will be integrated into championships from 2023.”

Testing of the environmentally-friendly top level hybrid cars begins early next season.
