I like to think that in the sports car bracket the lotus cars are the lightest cars that are still practical. Any less and you have to be hard core to drive them to/from the track.
That's their niche.
I can see a BEV Evora being a thing. It's mostly a GT car.
I cannot see a BEV Elise unless they make a deal with tesla for supercharging and even then who wants to do 50laps of Donnie followed by 30 mins at the supercharger?
Even if it had a 200 mile range (50kWh), that translates to 150 miles between charging stops, each of which would likely be 20+mins ... I think it would be hard going.
Our BEV does 300 miles on a full charge notionally, but at UK mway speeds that's more like 250 and then you usually only supercharge back up to 75% so actually you do about 200 miles between stops to optimise the total trip time. (Batteries charge fast up to about two thirds, then the charge rate tapers off, so you are better off using only the bottom 5..75% of the battery).
At 200 mile per stop, that's ok. Need a piss by then anyway

but at 100 miles per stop it would be a pain.
