What is a derivative?

You may be wondering when creating your advert what derivatives are? Derivatives are a brief overview of details which are important to car buyers.


Derivatives are made up of:

Engine size – The engine size is measured in litres, the bigger the engine size, the more powerful the car is but will consume more fuel than smaller engines.

Car body style- This normally depends on the size of your car and different features. Examples include, coupe, hatchback, convertible and estate.

How many doors – The amount of car doors including the boot of your car, this can change depending on different car models.

How many seats- The number of seats in your car when manufactured, this doesn't include any optional extras or modifications. 

Fuel type – This is the fuel you fill your car with to power the car. Examples are petrol, diesel, hybrid cars (electric/petrol or electric/diesel) and complete electric cars where charging is required.  

Transmission – The way your car is controlled and how you drive the car. Examples are manual, automatic and semi- automatic.

CO2 emissions – This is normally displayed as g/km which shows how much carbon dioxide is released when driving the vehicle. The lower the car has, the better it is for the environment.

BHP – Also known as brake horse power, BHP is how much power your car releases and is measured at the fly wheels. This shows the performance of the engine and how much work a car can do. The average car has around 100 BHP depending on engine size.

Please note: PSI is different to BHP, PSI (pounds per square inch) is slightly different and is higher than your BHP.
