The FIA Electric GT is an all-electric motorracing ruleset, unveiled by the Fédération Internationale de l'Automobile on 21 April 2021 as part of a wider move towards electrification by the motorsport body.[1] Based on the existing GT3 formula to reduce potential costs, the Electric GT formula will allow manufacturers to use either 4WD or RWD layouts, as well as develop their own powertrains and batteries, albeit with the incorporation of standardised parts.[1]

Background

The FIA had been investigating a potential electrically based GT formula since 2019, after the successful debut and development of the FIA Formula E Championship for single seaters.[2] These plans were partially formalised at a meeting of the World Motor Sport Council on 16 December 2020, although it was not until 21 April 2021 that the FIA officially unveiled its initial Electric GT formula.[1]

History

The FIA Electric GT formula was officially unveiled on 21 April 2021, with the announcement detailing key aspects of the technical rulebook and expected performance targets.[1]

Rules and Regulations

The Electric GT formula would be heavily based on the existing GT3 formula, which was used by various series supported by the FIA in sportscars.[1] As a result, the majority of Electric GT designs were expected to be interchangeable with existing GT3 cars, potentially allowing full conversions between cars, or would be based on road-going designs.[1]

Technical

The initial plans for the FIA Electric GT formula were unveiled on 21 April 2021, and featured estimations on speed, acceleration, power-output and weight limits, as well as outlining the areas of development that manufacturers could focus upon.[1]

Powertrain

The Electric GT ruleset was to allow manufacturers to fully develop their own powertrains, which could feature either two or four motors, as well as either 4WD or RWD configurations.[1] Powertrains would also have to incorporate a form of energy re-generation, which was to be capped at 700kW, with a maximum power output in the region of 430kW.[1]

The Electric GT formula was expected to create cars that could accelerate between 0 - 100 kph in 2.4 seconds, and reach a top speed of c. 300 kph.[1]

Batteries and Fast Charging

The Electric GT rulebook would also hint at manufacturers being able to develop their own battery systems, albeit in partnership with Saft, an electronics specialist under the ownership of Total.[1] Manufacturers would have to use specified parts of Saft's design, including their specialist lithium-ion pouch cells, to design their own battery systems, which would initially be restricted to the layout of the battery, rather than its output/efficiency.[1] Indeed, battery capacity would be capped at 87kWh for the first generation of FIA Electric GT, using the existing Saft cell designs.[1]

As part of the battery systems, Saft would also supply manufacturers with designs and equipment to enable fast charging during races, which would be limited to 700kW.[1] The aim was to allow up to 60% of the battery to be recharged within a few minutes, although this would require more infrastructure to be installed at the venues alongside development by Saft and manufacturers.[1]

Chassis and Weight

Electric GT would be based on one of two existing chassis designs, with manufacturers able to choose between a road car design, or an existing GT3 chassis.[1] Regardless, each car would have to reach a minimum weight between 1,490 kg and 1,530 kg, as well as meet the FIA's increasing safety standards in order to legally comply with the regulations.[1]

Software

In terms of software the Electric GT formula would incorporate various existing systems used in GT3, including traction control, anti-lock brakes and stability assistance.[1] Furthermore, teams would also be allowed to specifically control the torque out-put of each motor/wheel, dubbed "Dynamic Vehicle Control", as a counter to the increased weight compared to the standard GT3 design.[1]

Sporting

The sporting rulebook for the Electric GT formula has yet to be announced.
