According to user reports, real-world fuel consumption is on average about 20% higher than advertised. This difference tends to be higher for newer cars - drivers claim that cars less than 10 years old consume on average 30% more than advertised, while for older cars this difference is on average up to 10%.
To compare the fuel efficiency of cars, we offer a "Fuel efficiency score" which shows the fuel efficiency (higher score is better) of similar cars (by engine power, application, etc.). More about "Fuel efficiency score"
Select a manufacturer to check real-world fuel economy for specific car models.

¹ Average real fuel consumption difference indicates average difference between advertised fuel economy and real-world fuel economy reported by users, and is averaged across all of the manufacturer's vehicle models. For more information on specific models, click on the manufacturer's name.

² The fuel efficiency score evaluates the fuel efficiency of all vehicles from this manufacturer compared to similar vehicles by engine size, horsepower, body type, age, etc.. For example, a fuel efficiency score of 3 means that about 70% of similar cars are more fuel efficient. The score is calculated taking into account both advertised and actual fuel consumption.
