Formula E Gen3

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.

Specifications
The theoretical top speed is 322 km/h. The battery is also designed to handle "flash-charging" at rates of up to 600 kW, 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 2970 mm and the weight is 760 kg without the allocation of 80 kg for the driver, which brings the weight to 840 kg. The power-to-weight ratio is therefore roughly equivalent to a Audi RS5 Turbo DTM.

GENBETA
The GENBETA is a modified version of the Gen3 racecar. It has enhanced battery output, all-wheel drive, softer iON Race tyre compound, and 3D printed front wing endplates, wheel fins and a wind deflector. It has been used to break two different world records.

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. 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.

Single-seater acceleration record
In January 2024, Reem Al Aboud set a new record for FIA single-seater acceleration. She drove the GENBETA from 0-100km/h (0-60mph) in 2.49 seconds, beating the previous benchmark of 2.6 seconds, which was set in a Formula One car.
