Who is right? We're simply using slightly different measurements of power output to some manufacturers. We always quote bhp for all cars to allow for accurate, consistent comparisons across different brands. Some car manufacturers still quote a power output rating called PS, which stands for Pferdestrke literally, 'horse strength'. 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 PS to reach a rough bhp figure. If you want to be completely accurate, multiply the PS figure by 0. One bhp is equivalent to Torque of the engine is also measured. This is the turning power of the engine or how hard it can push you forward.
Generally a diesel engine will have more torque than a petrol engine due to the longer stroke of the piston and the compression involved to ignite diesel fuel generates more turning power.
Also the type of engine can have a factor on the torque produced. A V type example V8 engine or boxer engine will produce more torque than a typical straight configuration. This is because in a V or boxer engine the pistons are firing down on both sides of the crankshaft producing more turning power or torque. Torque is measured in Nm Newton metres or ft lb foot pound with 1 Nm being 0.
