How We Rank These Cars

The best performance cars rank vehicles by their weight-to-horsepower ratio.

The weight-to-horsepower ratio is calculated based on a vehicle's curb weight and horsepower at the trim level - the less weight one horsepower has to pull, the better performance a vehicle can provide. For cars with a ratio within 0.1 of each other, lighter vehicles always have the advantage in performance and are ranked to reflect that. For each vehicle, we also show the iSeeCars Score which rates the overall quality of a vehicle.

The 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).
