I'm not at all sure I agree. The performance versions of the Tesla are impressive, and turn great lap times. Clearly, enthusiast owners that do track days upgrade tires, brake pads and sometimes more. But in the end, the cornering prowess and times are well into the sports car range. These things are not just 1/4 mile monsters. The recent crop of performance oriented "family car" EV's are stunningly good.
Battery temperature and reduced performance after a few laps can still be an issue. I wonder if the latest M3P can finish 15 laps without reducing power. Also, these cars are heavy and tough on tires during a track day.
By way of comparison, my quite capable Jag F-Type 400HP convertible will turn 1:04.5 lap times at Lime Rock Park on the OEM crummy tires. The M3P is a full 5 seconds faster, and that was done on Falcon Azenis street tires (which are admittedly a fav of mine). I would require slicks and 100 more HP to match that.
And the lap record for a Spec Miata 1:01.10 (normally around 1:02.2)
