How this comparison works

Only genuine rivals are compared: same model year, same EPA size class, same drivetrain, similar weight and power, and both mainstream or both premium brands. Figures come from FuelEconomy.gov, EPA and NHTSA; fuel costs use current US prices from the Energy Information Administration.
