Which cars have the best mpg?Back

In a financially challenging market, buying a new or used car can seem daunting. Most people are looking for best mpg cars, meaning those cars that can offer the most miles to the gallon, therefore saving money in fuel and running costs.

But which are the best cars for mpg currently on the market? Most motorists assume that conventional petrol and diesel engines which contain a small cylinder capacity will be the most fuel-efficient cars with the best mpg, however this is not always the case. In fact, for each engine size, the fuel economy can greatly vary and relies on factors such as how well the engine is designed, built and tuned. It is therefore better to consider the vehicle’s mass or its weight, meaning the smaller the mass of a particular car, the better its fuel economy.

In recent years, fuel economy in cars throughout Europe has dramatically improved thanks to an agreement put in place between the European Commission and the ACEA (the Association of European car manufacturers) to reduce the CO2 emissions in cars, and with the significant increases in fuel prices in recent years, there has been a renewed interest in purchasing smaller city cars and superminis which offer lower emissions and therefore will cost less to tax.

According to the SMMT, the average fuel economy in new petrol cars in the UK is approximately 42mpg and for new diesel cars is 48mpg, although these are very general averages as they need to account for the large variations in fuel economy across a wide range of vehicle classes from the most fuel efficient city car right through to the most gas guzzling Sports Utility Vehicle. So, if you find a car which offers a higher mpg than the average, then you are on to a good thing.

Below is a list of the top ten new car models in 2012 which are currently offering the best mpg. Please note that these results are based on the official average mpg, so in reality the figures might be more than 10 per cent out. You will find that all of the cars detailed below are in tax band A which means you won’t have to pay any road tax for at least the first year.

Before you make that all important decision on the best mpg car to buy, remember that there is more to the running costs of a car than simply its fuel costs. Depreciation plays a huge role in how cost-effective your car will be over a three year period, so remember to consider this alongside the insurance, servicing and tax costs before you make a purchase.
