The Spark SRT05e, also known as the Spark Generation 2 or Gen 2, is a race car chassis, to be used as the base car for the ABB FIA Formula E Championship between the 2018/19 and 2021/22 Championship.[2] Built by Spark Racing Technologies with assistance from Dallara as a replacement for the Spark-Renault SRT_01E, the Gen 2 was be the first FE car capable of completing a full race distance, having been fitted with a battery constructed by McLaren Applied Technologies.[2]

22 Gen 2s were sold to the eleven entrants 2018/19 Formula E Championship, along with a full set of spares for each chassis, with two additional examples retained by the series for promotional events.[2] The examples sold to the teams were then be retrofitted with powertrains developed by one of FE's nine approved manufacturers for season five, as per the FIA's regulations.[2]

The SRT05e was receive a "face-lift" ahead of the 2020/21 Championship, identified as the "Evo" package, which will implement "self-punishing" bodywork after complaints about aggressive driving in the SRT05e's debut season.[3] However, this implementation would be delayed due to the impact of the Covid-19 pandemic in 2020, with tentative plans to introduce the update in 2021/22.[4]

Competitive History

The Gen 2 made its public debut at the Geneva Motor Show on the 6 March 2018, with deliveries to teams following soon after for testing.[1] The SRT05e subsequently made its public test debut during the 2018 Valencia Test, which was attended by all eleven entrants to the 2018/19 season with nine different manufacturers building powertrains.[5] The fastest time of the test would be recorded by António Félix da Costa at the wheel of the BMW iFE.18 variant of the Gen 2, a 1:16.977, while Nelson Piquet Jr. covered the most distance in the Jaguar powered version.[5]

Development History

Spark Racing Technologies were among a number of companies to apply for the tender to build a new FE car for the 2018/19 season when the FIA and Formula E Holdings opened applications in March 2016.[6] They won the tender with ease having successfully obtained the tender for the first FE car, the Spark-Renault SRT_01E back in 2012, and immediately announced that Italian racing specialists Dallara would partner them on the project once again.[7] The design process began late in 2016, with several proposed designs submitted to the FIA and Formula E for approval.[2]

Formula Creative

The FIA and FE approved one of the Spark designs in early 2017, releasing several CAD renderings by Spark in February 2017.[8] These designs were steadily evolved over 2017, with Spark and Dallara ultimately getting approval to build a version of their final design at the end of the 2017 season.[2] The final design was revealed on the 30 January 2018 with a series of HD images and renderings of the new car, dubbed the "Gen 2", with the full public unveiling of the first chassis staged for the 6 March 2018 at the Geneva Motor Show.[2]

Spark SRT05e Evo

The first official renders of the Spark SRT05e Evo package.

After receiving widespread praise for its radical design, the FIA and Formula E agreed to extend the use of the SRT05e for an additional season, meaning it would serve as the base chassis for the series for four seasons.[9] This announcement was followed by news that the SRT05e would receive a "facelift" ahead of the 2020/21 season, which was designed to "punish" drivers for making contact.[3] The update was requested by several drivers and teams after the SRT05e proved particularly robust during its debut season in 2018/19, allowing drivers to be more aggressive than they otherwise could have been.[3]

The first images of the "Evo" update to the SRT05e were revealed on 4 February 2020, and would show major revisions to the front and rear bodywork.[10] The bodywork covering the front wheels was removed, and instead replaced with a Spark-Renault SRT-01E-style front wing, designed to be more delicate than the original.[10] At the rear, meanwhile, the coverings over the rear wheels had been removed, and were instead replaced by a shark-fin down the spine of the chassis, as well as a pair of angled winglets to form a partial rear-wing.[11]

Production of the "Evo" update was cancelled entirely to introduce the Gen 3 car for the 2022-23 season.
