Highest fuel consumption

40 cars with worst fuel mileage. Updated August 2021.

Fast cars need powerful engines. Bigger engines need more fuel due to heat and mechanical friction.

This list shows best gas mileage in miles per gallon (USA gallon) as measured by automotive press and car manufacturers.

Gas mileage is highly dependent on driving style, route and weather conditions, therefore these results only have entertainment value and this list could be different if all tests shared the same methodology and conditions.
