Power is a way of expressing how much ‘work’ a car’s engine can do, or how far and how fast it can ultimately force itself. The force the car uses is called torque,
A horsepower is a totally arbitrary measurement – dreamt up by James Watt when trying to compare the effectiveness of his steam engines against the horses they were replacing. One horsepower was deemed to be the equivalent of one horse lifting 33,000 pounds over one foot in one minute on the surface of the Earth. - See more at: https://www.carwow.co.uk/guides/glossary/what-is-horsepower#sthash.FwcTtyzT.dpuf
PS (pferdestärke), CV (chevaux vapeur) or DIN metric horsepower are exactly that – an attempt to make horsepower metric. A metric horsepower is the equivalent of 0.986 horsepower – this is why the Volkswagen Golf R is advertised with 300PS but only has 296hp. Equally, 300PS sounds better than 296hp simply because it’s a bigger number - See more at: https://www.carwow.co.uk/guides/glossary/what-is-horsepower#sthash.FwcTtyzT.dpuf
One horsepower equals 745.7 watts (0.7457 kW), though very few countries use this measurement – only really being popular in Australia and South Africa. - See more at: https://www.carwow.co.uk/guides/glossary/what-is-horsepower#sthash.FwcTtyzT.dpuf
Power is indicative of how fast a car ultimately is and how far the force of the engine can push it, so it stands to reason that more horsepower typically means a higher top speed. The force of an engine is what you feel when you accelerate and is known as torque. Torque often tells you more about how an engine feels to drive rather than how far it can push – hence why torquey diesels tend to feel so strong on the road even with modest power outputs - See more at: https://www.carwow.co.uk/guides/glossary/what-is-horsepower#sthash.FwcTtyzT.dpuf

Torque:
The more torque an engine has, the more pull (or acceleration) it offers at lower revs.

Power is simple – the more you have of it, the faster you’ll go. - See more at: https://www.carwow.co.uk/blog/what-is-torque#sthash.xUlD2LP9.dpuf
if horsepower tells you how fast the car can ultimately go, then torque tells you how hard it can push you there. Torque matters as much, if not more so, than horsepower because it’s the force you feel when you accelerate. If you regularly tow a trailer or tourer, or frequently carry a fully-loaded car, then having plenty of torque is important because it helps you pull your load onwards. - See more at: https://www.carwow.co.uk/blog/what-is-torque#sthash.xUlD2LP9.dpuf
The best analogy to describe torque is to compare it to turning a nut with a spanner. Say your spanner is a meter long and you apply one newton of force to the end of it – you’re turning the nut with one newton-meter of force. Double the length of the wrench or the weight applied to its end and you double the torque being applied to the nut. In the UK, torque is typically measured in imperial foot-pounds rather than metric standard newton-meters – one Nm is equivalent to 0.738lb ft. - See more at: https://www.carwow.co.uk/blog/what-is-torque#sthash.xUlD2LP9.dpuf
