When driving, the car's electricity consumption and range, or fuel consumption can differ. Some reasons for this may be:
- Driving style.
- Extra equipment and cargo affect the car's weight or air resistance.
- Non-standard wheels can increase rolling resistance and air resistance.
- High speed causes increased air resistance.
- Road, traffic and weather conditions.
- The general condition of the car.
- Fuel grade.
- Not charging the car regularly from the mains.
