Car MPG Comparison by Brands & Models

When you are about to decide which car to buy, one of the main questions in your mind is the mpg (Mile per Gallon) of the car, in other words how much petrol or diesel your new car will eat. Car fuel consumption is a key consideration in choosing your car. Therefore, we have researched all the car makes and models and created a simple list of MPGs by car. We have listed the car MPGs by Imprial, US MPGs and also litres per 100 km. Please bear in mind that these mpg figures are official ones and they can be considerably different depending on how efficiently you drive the car. We took the average MPG of each car brand’s models. To see mpg for each model, check car brand pages.
