The Formula E Gen3, also known as Spark Gen3 or simply Gen3, is an electric formula race car designed for use in the FIA Formula E Championship. The car is the successor to the SRT05e, and is constructed by Spark Racing Technology. It is used as the base car for all manufacturers and teams from the 2022–23 Formula E World Championship onwards.

Development

In July 2020 it was announced that Spark Racing Technology would build the chassis and supply the front axles, Williams Advanced Engineering would supply the batteries, and Hankook would supply all-weather tires that incorporate bio-material and sustainable rubber.[1]

Specifications

The theoretical top speed is 322 km/h (200 mph).[2][3] The battery is also designed to handle "flash-charging" at rates of up to 600 kW (800 hp),[4] allowing pitstop recharging into the championship for the first time;[5] however, the introduction of fast charging has been delayed due to battery issues persistent throughout testing.[6] The wheelbase is 2,970 mm (117 in) and the weight is 760 kg (1,680 lb) without the allocation of 80 kg for the driver, which brings the weight to 840 kg (1,851.9 lb).[7] The power-to-weight ratio is therefore roughly equivalent to a Audi RS5 Turbo DTM.

World indoor speed record

During the 2023 London ePrix weekend, McLaren driver Jake Hughes set a new Guinness World Records for indoor speed by hitting 218.71 km/h (135.9 mph) inside London's ExCeL Centre in a modified version of the Gen3 racecar, known as the GENBETA. The previous record for fastest speed achieved by a vehicle indoors was 165.20 km/h (102.65 mph) set by American driver Leh Keen in a Porsche Taycan Turbo S at the New Orleans Convention Centre in 2021.[8]
