WEC reveals road-oriented 2020/21 prototype rules
The FIA's World Motor Sport Council has revealed new five-season-strong prototype rules that will come into force for the 2020/21 World Endurance Championship.
Agreed on Wednesday, the rules stipulate that both the internal combustion engine (ICE) and the front-axle energy-retrieval system must be based on units "destined for a series production car homologated for road use".
At least 25 cars for the ICE and another 25 cars using the hybrid system must be produced by the end of the year after the first WEC season they are used. The second season requires 100 units each.
Modifications to the engine are free, excluding the block, cylinder head and hybrid motor-generator.
Figures were also given for maximum power output, calling for 508kW for the ICE and 200kW for the hybrid system. Minimum weight is 1040kg, up from the 980kg minimum announced back in June, with a 48.5 per cent front bias (plus or minus 1.5 per cent).
Front and rear adjustable aerodynamic devices are allowed, with only two positions allowed for each. The driver is the only one allowed to change the positions.
A manufacturer or constructor will be able to homologate two different designs over the five seasons and will also be allowed five 'joker' upgrades over the same period.
