Some car manufacturers still quote a power output rating called PS, which stands for Pferdestärke (literally, 'horse strength'). It's alternatively known as DIN (Deutsches Institut für Normung ) hp as opposed to SAE (Society of Automotive Engineers) bhp.

PS is a slightly higher figure than the SAE bhp that we quote, so that's where the discrepancy creeps in.

As a rule of thumb, you can knock off one PS for every 100PS to reach a rough bhp figure. If you want to be completely accurate, multiply the PS figure by 0.9864 to reach the bhp total, or bhp by 1.0139 to get back to PS.
So it looks like its the bloody Germans, not the Belgians.....
