Mpg stands for miles per gallon, and is used to show how far your car is able to travel for every gallon (or 4.55 litres) of fuel it uses. The combined WLTP fuel economy figure provides a general overview of a car's fuel consumption over a variety of speeds and road types.

BHP rates the engine performance of vehicles and stands for the brake horsepower.

CO2 is the amount of carbon dioxide emitted by the vehicle in grams per kilometre travelled, the lower the CO2 emissions the cleaner the vehicle is for the environment.

Road Tax is based upon the CO2 emissions of the vehicle and is split into 13 bands from A to M. The higher the letter the greater the cost of tax paid to drive the vehicle on public roads. In addition to the road tax detailed below, any vehicle that had a manufacturers retail price in excess of £40,000 when first sold, attracts a road tax supplement of an additional £320 per year. This is charged until the vehicle is 6 years old.
