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. The upgraded Gen3 Evo has been used from {{FE|2024–25}} season onwards. It is the first ever Formula E car with all-wheel drive to race internationally.{{cite web |url=https://www.fiaformulae.com/en/news/496038 |title=Formula E and FIA unveil GEN3 Evo race car capable of 0-60mph in 1.82s |website=www.fiaformulae.com |publisher=FIA Formula E |date=25 April 2024 |access-date=17 October 2024 }}

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.{{cite web |url=https://www.fia.com/news/fia-and-formula-e-build-ever-more-relevant-future |title=The FIA and Formula E Build Ever More Relevant Future |website=www.fia.com |publisher=FIA |date=1 July 2020 |access-date=7 December 2022 |archive-date=30 November 2021 |archive-url=https://web.archive.org/web/20211130151110/https://www.fia.com/news/fia-and-formula-e-build-ever-more-relevant-future |url-status=live }}

The electric motor produces a maximum 350 kW in attack mode and 300 kW in race mode. Because of the new front powertrain the GEN3 car is capable of a regenerative possibility of 600 kW (250 kW at the front and 350 kW at the rear) which doubles the amount of regeneration of the GEN2 car (Spark SRT05e). {{Cite web |date=2022-04-28 |title=New Gen3 Formula E car unveiled |url=https://the-race.com/formula-e/new-gen3-formula-e-car-unveiled/ |access-date=2023-08-11 |website=The Race |language=en-GB}} The power-to-weight ratio is therefore roughly equivalent to an 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, then-McLaren driver Jake Hughes set a new Guinness World Record 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.{{Cite web |date=2023-07-28 |title=Formula E driver sets indoor world speed record |url=https://www.espn.com/f1/story/_/id/38086304/formula-e-driver-jake-hughes-sets-indoor-world-speed-record |archive-url=https://web.archive.org/web/20230729033622/https://www.espn.com/f1/story/_/id/38086304/formula-e-driver-jake-hughes-sets-indoor-world-speed-record |archive-date=2023-07-29 |access-date=2023-07-29 |website=ESPN.com |language=en}}

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.{{Cite web |date=2024-03-05 |title=Formula E sets new acceleration benchmark in motorsport |url=https://www.fiaformulae.com/en/news/www.fiaformulae.com/en/news/491008 |access-date=2024-07-22 |website=The Official Home of Formula E |language=en}}
