Good to know
Mechanical horsepower (hp) is about 1.4% larger than metric horsepower (PS): 1 hp is about 1.014 PS. The same engine therefore has a slightly higher PS figure than hp figure.
This is metric horsepower (PS, CV), 735.49875 W. It is about 1.4% smaller than mechanical horsepower (hp, about 745.7 W), so a car rated at 150 PS has about 148 hp.
This is mechanical (imperial) horsepower, 550 ft·lbf/s or about 745.7 W. Metric horsepower (PS, CV) is about 1.4% smaller at 735.49875 W, and electric motors are sometimes rated in electrical horsepower of exactly 746 W.
