The real technological marvel here is the tire manufacturers.
I took an RC car (Traxxas Rustler 4x4) designed for 11.1V(3s) and strapped a 22.2V(6s) system to it, upgraded all transmission parts and it holds up well.
However you can't go full throttle without full ground contact (and barely even then) without shredding the tires into atoms. I've tried reinforcing with glass fibers and various glue compounds but it always finds a weak spot and propagates.
I think the car does around 160kmh, I've GPSed it to 140 but since it's an off-road vehicle it just takes off at those speeds. I assume free-rolling the tires reach over 200kmh, with some napkin math the tires rotate at over 9000RPM (150 per second).
Napkin AI math says the tire could experience as much as 4000G.
It's honestly "easy" to build an "unlimited horsepower" car with EV technology, high-quality cells, high-voltage, expensive components takes you there, tires though...
about 10hp/mph, and 6 lbs/hp, so the trick here is traction control. any skip,hop, or bump, that loostens up one wheel relative to the others invites wheel spin, asymetric wheel spin at 300mph, goes bad instantly for the RUD, so the software has to be every bit as good as the hardware

> Total kerbweight stands at 2,480kg
> 308mph
This car has more kinetic energy than a fully loaded semi truck traveling at 70mph.

Also For anyone who wants to watch a lap of nurburgring, it's absolutely insane...https://www.youtube.com/watch?v=td_c1zeEn2Q
Another truly insane electrified lap - Porsche 919 lap, at under 5.5 minutes!

That's insane!
I'm guessing the weight of the drivers balls is limiting factor here. Any lighter and the car would not be able to go so fast.

There’s enormous debate about the 511km/h record measurement at Le Mans, so let’s wait until this is cross-checked by competitors ;)
