I was under the impression that smaller batteries had a limit to peak power draw. Perhaps not important if you have an ultra-light vehicle and you’re not attempting to build a competitor to the Plaid.
Perhaps thermal management could be somewhat opened up to the driver with short "sprints" possible, to add some more driver involvement to the experience.
I’d be very happy with a light weight EV Miata that went 0 to 100km/h in under or around 4 seconds. Not Model S Plaid or high end 911 fast, but still by far the fastest production Miata.
There's a full build series too by the company that made it. I think £20k was mentioned as the cost of the conversion kit if they were to sell one. 120 miles range.
I've mostly been keeping an eye out on the aircooled VW conversions (or that EV 1968 Mustang on youtube).
It'll really get interesting when you see more from-scratch cars that don't have the ICE history built in. There are a lot of changes that could be made in design. If the government didn't love to get in your business so much, maybe there could be a world of street-legal EV karts.
Many are still on lead-acid batteries (36V or 48V) but you didn't specify battery chemistry. :)
Tesla's approach seems to be to optimize their cells for energy density rather than power density. They can do that because the packs they use are huge. On the other hand you have relatively small batteries that go in hybrids that are optimized for power density.
