Warum zeigt die Schweiz kW statt PS?
Seit 1992 ist in der Schweiz und der EU die Angabe der Motorleistung in kW (Kilowatt) gesetzlich vorgeschrieben. PS ist keine SI-Einheit. Dennoch verwenden viele Autofahrer und Inserate weiterhin PS, da es intuitiver ist. Unser kW in PS Rechner oben ermoglicht die sofortige Umrechnung in beide Richtungen.
Formel: PS = kW x 1,35962 | kW = PS / 1,35962

Why does Switzerland use kW instead of PS on car documents?
The EU directive 80/181/EEC requires power to be expressed in SI units (kW) on official documents. Switzerland adopted this standard in 1992. PS remains widely used in advertising and everyday speech but has no legal status in vehicle registration documents.

kW, PS and hp — What is the Difference?
kW (kilowatt) is the SI unit of power and the legally required unit on all Swiss vehicle documents (Fahrzeugausweis) and EU type approval certificates since 1992. When you see "110 kW" on a car registration in Switzerland, that is the official engine output figure.
PS (Pferdestärke) — German for "horsepower" — is the metric unit widely used in German, Swiss and Austrian car advertising. One PS equals exactly 0.7355 kW. Despite having no legal status on registration documents, PS remains the dominant unit in dealer listings, press releases and everyday conversation.
hp (horsepower) is the imperial unit common in British and American car journalism. One hp equals 0.7457 kW — slightly more than one PS (1 hp = 1.0139 PS). The difference is small enough that the figures are often used interchangeably in everyday speech.
Conversion Formulas
kW = PS ÷ 1.35962
hp = kW × 1.34102
kW = hp ÷ 1.34102
hp = PS × 1.01387
Why Do Swiss Car Documents Show kW?
EU Directive 80/181/EEC required member states and associated countries to switch to SI units (kW) on official vehicle documents. Switzerland adopted this in 1992. Every Fahrzeugausweis issued since then states engine power in kW only. PS figures in Swiss car advertisements are informal and not regulated — which is why the same car can look different depending on whether you read the advert (PS) or the registration document (kW).
Using kW When Calculating Swiss Vehicle Tax
Several Swiss cantons — including Bern, Aargau and Zurich — base the annual vehicle tax (Motorfahrzeugsteuer) directly on engine output in kW. Knowing your car's exact kW figure before you buy can help you compare the annual tax cost across cantons. Use the Swiss Car Tax Calculator to estimate your tax once you have the kW figure from the Fahrzeugausweis.
