- Advertised EV horsepower is usually the peak output available only for short bursts.
- The UN’s 30-minute rating shows how much power an EV can sustain for longer.
- Cooling, battery charge, and drivetrain design determine how consistently an EV delivers full power.
That EV you see advertised with over 1,000 horsepower should probably carry an asterisk and an explanation. Yes, it can deliver that much power, but only temporarily when you mat the accelerator. Look at its registration documents in some European countries, and you might be surprised to see a much lower power figure than what the manufacturer advertises.
