Check a car's fuel economy and MPG
A fuel economy check shows the MPG figures returned in the available vehicle specification data. Depending on the vehicle, this can include combined, urban and extra-urban MPG.
These figures are useful for comparing models, but they are not a promise of what every driver will achieve.
Understanding the MPG figures
- Combined MPG: a blended test figure commonly used for broad comparison
- Urban MPG: a test figure associated with lower-speed and stop-start conditions
- Extra-urban MPG: a test figure associated with steadier, higher-speed driving
Test methods have changed over time, so figures from vehicles of different ages may not be directly comparable. Some electric, hybrid, commercial or unusual vehicles may use other efficiency measures or have no MPG field.
Why real-world MPG differs
Traffic, short journeys, temperature, driving style, tyre pressure, load, roof boxes, maintenance, regeneration cycles and battery use can all change consumption. Use the supplied value as a reference and budget conservatively.
Estimate fuel cost
Take your expected annual mileage, divide it by a realistic MPG figure, convert gallons to litres and multiply by the current fuel price. Because fuel prices change, REGUP does not hard-code a future annual cost into this datapoint.
Data availability
If no combined, urban or extra-urban figure is supplied, REGUP displays Not available. Missing specification data does not mean the vehicle uses no fuel.
This paid datapoint reuses the existing licensed vehicle-specification dataset. Combine it with tax, insurance, service history and valuation information for a fuller running-cost picture.

Fuel Economy / MPG Check FAQs
Will I achieve the displayed MPG?
Not necessarily. The supplied figure is a test or provider value. Driving, weather, journeys, load and condition affect real-world economy.
What is combined MPG?
It is a blended comparison figure from a test cycle. It helps compare vehicles but is not a guaranteed personal result.
Why is MPG Not available?
The specification record may not include an MPG field for that vehicle, fuel type or model. REGUP does not invent a value.
Does this check calculate current fuel prices?
No. Fuel prices change. Use the supplied MPG with your expected mileage and a current local fuel price.
Compare MPG before choosing the car
Review the supplied figures, estimate your own mileage and budget for real-world use rather than relying on the headline number.
