    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 :D

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

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

    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 :D

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