Real fuel consumption

We have aggregated user feedback on the car's actual fuel consumption over a daily driving cycle from a number of sources and compared it with the manufacturer's fuel consumption figures. On average, manufacturers' fuel consumption figures are 15-20% lower than actual consumption. See more fuel economy data and fuel efficiency scores by manufacturers or click on the manufacturers to see how the real fuel consumption of specific models differs from the manufacturer's claims.

Check most fuel efficient cars by vehicle type according to advertised and real fuel consumption.

Will a diesel car always be the most economical choice compared to its petrol counterpart? What else should be considered when choosing a car based on engine type?

The fuel consumption reported by users does not reflect the experience of all users, may be selective (depending on the driving conditions, driving style, technical condition of the car and other circumstances) and should therefore not be taken as a representative indicator.
