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.
EU type-approval data
| Years | Powertrain | Engine | Power | Mass | CO₂ |
|---|---|---|---|---|---|
| 2016–2019 | Petrol | 2997 cm³ | 307 kW (417 PS) | 1954–2025 kg | 218–223 g/km (NEDC) |
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.
