About kilowatts and horsepower
One kilowatt is 1.34102 mechanical horsepower. Multiply kW by 1.341 to get hp, or add a third for a quick estimate that is about 0.6% low: 75 kW gives 100 hp against the exact 100.58 hp.
The watt is the SI unit of power, so European car documents, electric car specs and motors list kW. Buyers used to horsepower convert those figures to compare cars, especially between European and US spec sheets.

- 55 kW (a small city car engine) is 73.76 hp
- 100 kW (a mid-size family car engine) is 134.1 hp
