About PS to kW
Metric horsepower (PS in Germany, CV or ch in France) equals about 0.7355 kW, so hp × 0.7355 = kW — a 150 hp engine is about 110 kW. Mechanical (imperial) horsepower is slightly more, about 0.7457 kW.
Car makers quote engine power in PS or hp and increasingly in kW, so this conversion is everywhere in vehicle specs. To go back, divide kW by 0.7355 to get metric horsepower.
About the units
Horsepower (metric) (PS) — Metric horsepower (735.5 W) — PS in Germany, ch in France, 馬力 in Japan — is the continental European car-power unit, about 1.4% smaller than the mechanical horsepower.
