Usually a car's power is denoted in terms of PS. What does this PS mean? How is it measured? What are the other units in which a vehicle's power can be measured?

PS stands for pferdestarke(dont remember exactly)....most commony car power is measured in PS & BHP(break horse power)...BHP & PS are two measures adopted by two different standard agencies...

1BHP=.986PS

& 1BHP=745watts

There is a machine called engine dynamometer to measure the engine output. Normally they will be available with the manufacturers and the testing labs 




I am on right click mode. Always. For more options.

Hi, regarding the engine dynamometer, It is setup which has a flywheel like arrangement connected to the engine's output shaft. A rope is wound around the flywheel and on the one side of the rope weights can be suspended. The engine is started and at a constant rpm the with a constant weight the torque is measured. Then the weight is increased and again the rpm is measured. Then some formulas are used to arrive at the power of the engine
