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 |
|---|---|---|---|---|---|
| 2025 | Petrol | 1598 cm³ | 110 kW (150 PS) | 1487 kg | 145–148 g/km (WLTP) |
| 2025 | Petrol | 1598 cm³ | 132 kW (179 PS) | 1500 kg | 151 g/km (WLTP) |
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.
