How We Rank These Cars
The iSeeCars "Best Gas Mileage" lists rank cars, trucks and SUVs based on the highest mpg and most fuel-efficient drivetrain for each vehicle.
Along with the Best Gas Mileage scores, the lists show additional iSeeCars scores because we believe other factors should be taken into account to find the best overall vehicle. If there is a tie in mpg between vehicles, we use the overall iSeeCars Score to break the tie.
The overall iSeeCars Score is an analysis of three factors: reliability, resale value and safety. It is calculated based on the latest research and analysis by our data science team. The data analysis comes from over 12 million new and used vehicles in our Longest-Lasting Cars and 5-Year Depreciation Studies, combined with NHTSA and IIHS Safety Ratings.
Vehicles are scored in three categories:
Reliability
The reliability score represents an analysis of iSeeCars' proprietary research on the longest-lasting vehicles.
Value Retention
The value retention score is based on our data science team's statistical analysis and prediction of 5-year depreciation from MSRP to determine which cars hold their value best, using US Bureau of Labor Statistics data to adjust for inflation.
Safety
The safety score is calculated based on the last five years of crash test ratings from the National Highway Traffic Safety Administration (NHTSA) and incorporates the latest Top Safety Pick information from the Insurance Institute for Highway Safety (IIHS).
