The Most Economical Cars on Sale in 2019 in the UK for 10 Different Categories

Looking for the most economical car on sale right now? If you want to save money on running your next car, then you must read our Green Car Guide – which guides you to the most economical and lowest emission cars in ten different categories. All of the cars in our Guide are available to buy in 2019 and represent the most efficient cars in their class, and the latest 2019 Vehicle Excise Duty (VED) rates and 2019 Benefit in Kind (BIK) company car tax rates are included.

Each Green Car Guide category is broken down into the best diesel cars – which are generally the most economical for lots of motorway miles – and the best petrol cars. Also included are hybrids, plug-in hybrids and electric cars – which are ideal for driving in urban areas due to their low, or zero, tailpipe emissions. Many petrol or diesel cars achieve fuel economy of 60mpg or 70mpg – or more in the case of plug-in hybrids.

We have provided expert and independent advice about cars that are efficient and great to drive for over 12 years, and Green Car Guide has reviewed all of the cars in our Guide.

More and more cars are appearing with identical combined miles per gallon figures. In this case, we will rank the cars based on aspects such as their emissions (which in some cases may be slightly different even though their combined miles per gallon figures are the same), extra urban miles per gallon, and how much car you get for your miles per gallon.

Our Green Car Guide is updated every month so check back soon for the latest green and fuel efficient vehicles added to the list!
