Car database: specs, MPG and running costs
Browse 240+ popular cars, trucks, SUVs and EVs by make, model and year for official EPA fuel economy, annual fuel cost, electric range and NHTSA safety ratings. Line any two up in the side-by-side comparison tool.
Because the figures come straight from the U.S. EPA and NHTSA rather than marketing brochures, you can compare a hybrid against its gasoline twin, a used model year against the new one, or an EV against the car it replaces, on the numbers that actually decide the monthly cost.
