BHP vs PS

MetzgerMeister

What's the difference in measurement between BHP and PS?

PS = PferdeStärke which is german for horsepower.

BHP = brake horsepower

Is PS used to measure crankshaft power and BHP used to measure wheel horsepower?

Fair point but that's not really happening is it? Reminds me of another thread here regarding mpg and l/100km

peasant

no ..kilowatts is for hairdryers ...mine's got 1.2

afaik you're correct about PS being at the crankshaft and bhp somewhere further down the drivetrain, possibly the brakes/wheels

Mine's a Remmington 3.0 turbo

This would be the power left after taking into consideration the power lost due to

gearbox, alternator, differential, water pump, and other auxiliary components such as power steering pump, muffled exhaust system, etc

surely the power to weight ratio is more interesting

Yes but how are you measuring the power so you can compare it to the weight?

But when's the last time anyone has asked at a dealer "how many KW does this have?"
