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. Specifications 
The theoretical top speed is . The battery is also designed to handle "flash-charging" at rates of up to , allowing pitstop recharging into the championship for the first time; however, the introduction of fast charging has been delayed due to battery issues persistent throughout testing. The wheelbase is  and the weight is  without the allocation of 80 kg for the driver, which brings the weight to . 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 218.71kmh/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 165.20kmh/102.65 mph set by American driver Leh Keen in a Porsche Taycan Turbo S at the New Orleans Convention Centre in 2021.
