Car running costs comparison tool

Compare Car Running Costs

The Green Car Guide Car Running Costs Comparison tool allows you to compare running costs for all new cars on the market.

CO2, MPG and VED data 

The Car Running Costs Comparison tool also provides a quick and easy way to view CO2, MPG and VED data, as well as fuel costs, for all new cars.

Total running costs 

You can enter your annual mileage and the length of time you want to keep the car, and the Car Running Costs Comparison tool will provide you with total running costs, as well as a total cost for the car.

Compare fuel costs

Running costs are comprised of service and repair, fuel, road tax and breakdown cover. Standing costs are comprised of depreciation and insurance group. Running costs and standing costs provide the total cost.

Compare running costs of up to three vehicles

You can then compare this car with up to two other vehicles.

Car Running Costs Comparison tool uses more realistic real-life fuel economy figures

Uniquely, the tool uses more realistic real-life fuel economy figures for cars such as plug-in hybrids and E-REVs than the misleading official NEDC figures for this type of technology, providing more accurate costs for real-world use.

Compare running costs for petrol cars v diesel cars v hybrid and electric cars

Motorists want cars that have affordable running costs, and this is more important to car buyers than how ‘green’ a car is. Green Car Guide’s Car Running Costs Comparison tool allows visitors to compare petrol cars v diesel cars v hybrid and electric cars. Comparisons between vehicles with different fuel and powertrain technologies provide some interesting results.

Which car is most efficient for you?

The new tool complements the animation, ‘Which car is most efficient for you?’, produced by Green Car Guide and supported by the Energy Saving Trust and Fleetdrive Electric. Featuring a voiceover by TV presenter Robert Llewellyn, the animation explains the differences between petrol, diesel, hybrid, plug-in hybrid, extended-range electric vehicles and pure electric vehicles, and guides people about which technology is likely to be most efficient for their driving. There are short animations about each of the individual technologies, lasting around two minutes each, as well as a longer ten-minute version for people who are keen to learn more about low and ultra-low emission vehicles.

Overview about different fuels and technologies

Visitors to Green Car Guide can view the ‘Which car is most efficient for you?’ animation to gain an overview about different fuels and technologies, and then use the new Car Running Costs Comparison tool to discover which actual vehicle will be cheapest to run.

Electric Car Guide animation

There’s also our Electric Car Guide animation, which provides a user-friendly and engaging introduction to electric vehicles.
