Tesla Model S P100D modified for the Electric GT racing series – note lightweight biocomposite roof & bonnet (hood)

Originally, the Electric GT circuit racing series was to run Tesla Model S P85+ only.1 Now it has been decided to use P100D.
Why the change of policy? A significant problem with electric vehicles in circuit racing is battery temperature.1 P100D has a substantially redesigned battery cooling system which is better suited to circuit racing.2
Among the modifications allowed under the regulations is weight reduction. The racer which has recently been revealed (above) is 500 kg (1,100 lbs) lighter than a production P100D. This is due in part to replacement of some panels with a lightweight biocomposite, which has apparently been chosen for its environment-friendly, biodegradable properties, in addition to its light weight.3
This Model S is credited with a 0-60 mph time of 2.0 seconds (0 to 100 km/h 2.1 seconds) – that's 0.3sec better than a stock P100D.
Races will be run on conventional race circuits, such as Silverstone & Nürburgring. Events will include 20-minute practice, 30-minute qualifying, & two races of 60 km (37 miles) each. First event is planned for August of this year.

If the video above (however briefly) is any indication, Electric GT has a drama that Formula E has so far lacked.
