That is why they make the brakes out of fancy carbon ceramics. You can still burn them but not in a single 400kph to 0. They do kinda suck when driving slowly

They do kinda suck when driving slowly as they only really work well when hot but electric cars can just brake with the engines at those speeds to make up for it. Though they are used in combustion engine sports cars too so it is not that bad. Just need to warm them up like tires when driving hard on a race track.
For sports cars carbon ceramic brakes also have the massive advantage that they do not fade with heat like traditional brakes.
- bitexploder 3y agoMost modern sports cars with proper brake fluid (higher boiling point) and some heat management have no problems with brake fade in steel discs. Many that track their GT3 / GT3 RS (Porsche 911) prefer steel discs due to the maintenance cost of carbon ceramic and properly designed steel discs perform just the same as carbon ceramics because the brake fade isn’t a big problem, even in a pretty extreme application like this. Not sure if the Rimac really needs anything otherwise as well. Plus, it has regen braking and a crazy cooling system to help there. Parents math was off about the amount of energy also. My car has carbon ceramic brakes (GT3). Two reasons: don’t need to be warmed up for full stopping power and way less brake dust. That is the only advantages in practice. On the track warming the brakes up is easy.
