| Gearbox: | Automatic | Manual | |
|---|---|---|---|
| Engine: | 2.9 Diesel | 2.0 Petrol | |
| Diesel (BMW 7 series) engines typically outperform gasoline engines in terms of fuel efficiency and low-end torque. This makes them more economical and better suited for towing or long-distance travel. However, gasoline (Subaru Impreza) engines mostly are lighter, quieter, and offer better acceleration and responsiveness, especially in smaller vehicles. For more information, see the article "Diesel or Petrol: Fuel Economy and Key Differences." | |||
| Camshaft drive: | Timing chain | Timing belt | |
| Engine chain usually needs to be replaced less often than the timing belt, but the cost of replacing the chain is usually higher. Chain motors are considered to be more reliable, but noisier and more vibration generating. | |||
