The Spark SRT05E, also known as the Spark Gen2, or simply Gen 2 is an electric formula race car designed for use in the FIA Formula E Championship. The car is the successor to Spark-Renault SRT_01E, and is constructed by Spark Racing Technology with assistance from Dallara, and will be the base car used by all manufacturers and teams from the 2018-2019 FIA Formula E Championship.[1] The car features a new 56 kWh battery from McLaren Applied Technologies, alongside the new Halo cockpit protection system,[2] and is the first Formula E car capable of completing a full-race distance.[3]

DevelopmentEdit

Initial DevelopmentEdit

On September 28 2016, McLaren Applied Technologies was announced to have won the tender to exclusively supply batteries for the Gen2 car.[4][5] Initially, the tender called for the battery to be supplied for two seasons, before it was announced subsequently that battery development would only be opened up for the 3rd Generation car, to reduce development costs for teams.[6]

On 9 January 2017, Spark Racing Technology was announced to have won the tender to supply chassis for the 2nd Generation Formula E Car.[7] On 12 February 2017, concept images of the 2nd Generation Formula E car were released.[8]

In September 2017, the SRT05E had its first shakedown run, held in secret at the Circuit Ecuyers, in Reims, France, with Anthoine Hubert at the wheel. The shakedown was used to evaluate the performance of the new battery, with the car completing over 400km of mileage, but running without the Halo driver protection device, or fully installed bodywork. [9]

In October 2017, the SRT05E successfully completed its first endurance tests held across three days, at the Monteblanco Circuit in Spain, once again, without the halo cockpit protection system, but with the full bodywork of the car installed. Four full-race simulations were also conducted across the three days, with Anthoine Hubert and Frederic Makowiecki at the wheel of the car.[10]

On 1 December 2017, the FIA, as well as Formula E Holdings announced via Press Release, that they would renew their exclusive partnership with Michelin to supply tyres for the Championship until 2021.[11]

On 30 January 2018, the SRT05E was revealed online with a series of computer generated images.[12] The launch date for the car was also set at 6 March, at the Geneva International Motor show.[13]

On 6 March 2018, the SRT05E was launched at the Geneva International Motor show by FIA President Jean Todt, as well as Formula E Holdings CEO Alejandro Agag.[14] The car was also revealed to be the first-ever race car to be fully conceived and project-led by the FIA, with the FIA organising the concept from design, through manufacture.[15]

The first manufacturer group test took place, behind closed doors at the Monteblanco Circuit in Spain from 28–30 March 2018. The track was modified to include two specially-inserted temporary chicanes, on the front and back straight, with lap times estimated to be around the 1:01 mark. On the first day of testing alone, 2000km of running was achieved among the teams.[16]

Mid life "Facelift"Edit

It was later confirmed on 18 January 2019, that similar to its predecessor, the Spark-Renault SRT01E, the SRT05e would also undergo a bodywork update ahead of its intended 3rd season of competition, the 2020/2021 season, while the car would also see its use extended until the 2021/2022 season.[17]

Subsequently, due to the Gen2 car being much stronger than the original Spark-Renault SRT 01E car, leading to the drivers becoming more aggressive and increased contact between the cars,[18] it was decided that the newer front of the car would be designed to be more fragile, in a bid to punish drivers for making excessive contact, and to force them into pitting for repairs. [19]

TechnologyEdit

Electric motorsEdit

Teams are able to use their own motor designs homologated with the FIA, or may procure one from an existing manufacturer with an FIA homologated design, at a cost of no more than €250,000.

ChargingEdit

The charging is done by the teams before the race.

TyresEdit

The cars are shod with 18in Michelin Pilot Sport All-Weather tyres, and are expected to last a whole race weekend, with one set of tyres per car.[20] Compared to the tyres on the previous car, the tyres are 2kg lighter at the front and 2.5kg lighter at the rear, allowing for a decrease of 9kg per 4 tyres.[21]

In video gamesEdit

The car appears in the Real Racing 3 mobile game, and was added alongside the Brooklyn Street Circuit.[22]

Developers of racing simulator rfactor 2 added the car to the game in April 2019.[23]
