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.
