Ok so some of us may remember 'Electric GT Holdings' and their plan to launch with converted Tesla racing cars in 2017/18 which... did not happen. They were at one point backed by the FIA with a licence to be the Electric Production Car Series (EPCS). It somewhat seems they have lost confidence in this initiative.
According to Sportscar365, the FIA is seeking a promoter for a new set of electric GT regulations which were approved by the World Motorsport Council and named (unimaginatively) FIA Electric GT. The plan is for cars to more or less match current GT3 performance levels. More details:
Each “main race” would be 40 minutes in length and require cars to complete at least one mandatory recharging pit stop, utilizing a fast-charging system aimed to restore up to 60 percent of the battery power within three to four minutes.
[...]
The EGT platform features “many existing technologies” carried over from GT3 in order to keep development costs low, although with the target of introducing rapid recharging, which would be an “integral” part of each event [...]
Sportscar365 understands that a number of manufacturers, including Porsche and Audi, have shown early interest in the proposed championship, which is unrelated to Electric GT Holding’s Tesla-based production series that has faced a number of failed launches.
Bentley were also saying recently that an electric GT category would be of interest to them.
I think something like this is going to be inevitable eventually, though the path so far has not been plain sailing. Thought a separate thread on these new development was warranted.
