The new Hypercar regulations set to be introduced from the 2020-2021 World Endurance Championship have been confirmed with hybrid power made optional.

Open to both manufacturer effort and privateer teams, the new premier class category in WEC begins in September 2020 following the decline of LMP1 entries which currently sees Toyota as the sole hybrid factory effort left in the class.

The Hypercar rules have been opened up to allow entries to design a prototype car or develop a road-going machine into a hypercar in an effort to provide wider attraction to manufacturers and privateer teams.

The weight of each entry will be set at 1100kg with a powertrain output of 750hp, targeting an average lap time of 3m 30s around the Circuit de la Sarthe at Le Mans. The aerodynamics of each hypercar will have “free design” while sticking within FIA a safety criteria.

The key feature change is the option to run either hybrid systems or a combustion engine, with competition between teams managed by a Balance of Performance system which will be introduced.

Hybrid-powered entries will also have a energy restitution threshold for the front wheels in an attempt to level the playing field between two-wheel cars and the four-wheel drive hybrids.

ByKolles Racing has already confirmed it is developing a new hypecar prototype in preparation for the 2020-2021 season, while Toyota is expected to maintain its hybrid-powered TS050 LMP1 programme.
