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...
