a11y said:They do. A lot of european cars are listed in "ps" rather than "bhp" which is more common in the UK. No idea what the US/Canada use though, so mcbeee's could have 255 for all we knowbigshurv said:Don't some contries measure HP differently I think?.![]()
HP, as a unit to measure the power produced by an engine through a dynamometer (so through the rear wheels) and is the standard unit of power measurement in America, possibly Canada as well
BHP, has the same units as HP, but is measured by applying a "break" to the flywheel and was/is the standard unit of measure in the UK as well as the use of the German term PS, 1 PS = 0.986 HP
So the difference is that HP is the measurement of an engine’s power at the wheels and so include transmission losses, while BHP does not, thus for the same car/engine the specified BHP value will be higher than those specified as HP
The correct SI derived unit for power is the Watt
