Values are the official EPA label figures for each model year, shown as the lowest and highest value for the configuration. Electric models show energy use per 100 km. Real-world consumption depends on driving style, weather and load. Luggage and passenger volumes follow the EPA measuring method and can differ from the VDA figures used in Europe.

Years are registration years. Each range runs from the 10th to the 90th percentile of the values reported for new registrations; it is not an average. Mass is the mass in running order. For electric cars the power is the type-approval net power, which can be lower than the peak power in brochures.
