What is an economical car?

What constitutes an economical car will vary from person to person, but most motorists are looking for low running costs: low tax, low insurance and good fuel economy

High fuel economy or MPG tends to go hand in hand with low CO2 emissions and low CO2 emissions in turn means less car tax or company car tax. Thus, the most economical cars to run are often also environmentally-friendly cars.

Selecting a model in the list of most economical cars above will show more details on the model, including running costs, whole life cost and links to fuel and tax calculators.
