Frequently Asked Questions

Is HP the same as kW?

No. One mechanical horsepower equals approximately 0.746 kilowatts. Metric horsepower (PS) equals approximately 0.7355 kW. These small differences matter for precision comparisons.

Why do European cars use kW instead of HP?

Europe uses the SI unit system where power is measured in kilowatts. Many countries and manufacturers list both kW and PS (metric horsepower), though the US predominantly uses SAE horsepower.
