Automotive power discrepancies explained by measurement standards

Discrepancies between a vehicle's advertised horsepower and the figures listed in official documentation are often due to different measurement standards rather than fraudulent claims. In the automotive industry, manufacturers typically highlight maximum power in kilowatts (kW) or horsepower (cv) to emphasize performance during short bursts, such as rapid acceleration or overtaking.

For electric vehicles, specific regulations, such as UN Economic Commission for Europe Regulation No. 85, require a distinction between maximum power and the maximum power maintainable over a 30-minute period. This 30-minute metric represents the average useful power a system can consistently provide, which is often lower than the peak power the motor can deliver for shorter durations.
