Longest Distance on One Tank

Shortest Distance on One Tank

The Hyundai i10 sits at the bottom of our chart with just 330.29 miles for a full tank, although, this is partially due to the size of the tank itself as it has a capacity of 35 litres. For fuel efficiency, this car ranks in the top 20.

The Toyota Aygo takes the top spot when looking at the cost per mile at just 10.55p to the mile, whereas the Land Rover Range Rover sits at the other side of the table, with a significantly more costly 36.25p per mile.

In order to compile our original list of cars, ChooseMyCar your car buying assistant and Bad Credit Car Finance specialist took the top 50 most registered car models from the Department for Transport, specifically, ​vehicle licensing statistics: 2018​ (VEH0161).

Using Honest John, we were able to find the average miles per gallon (MPG) for these cars. We then compared that with the tank capacity using data from Car Leasing Made Simple, choosing the petrol model that was the closest match to the average MPG figure.

Using these figures, we were able to find out how many miles each car could travel on a full tank and how much on average it would cost to fill the tank using recent numbers from ​The AA​ which state that petrol costs 127.7p/litre. It should be noted that this is an average for the UK so prices may vary across the country, and prices are subject to change.
