Examples of this are:
- If the car is not charged regularly from the mains power circuit.
 - If the car is equipped with extra equipment that affects the car's weight.
 - The driver's driving style.
 - If the customer has specified wheels larger than those fitted as standard on the model's basic version, then rolling resistance increases.
 - High speed results in increased wind resistance.
 - Fuel quality, road and traffic conditions, weather and the condition of the car.
 
A combination of the above-mentioned examples can result in significantly improved consumption.
Note
Extreme weather conditions, driving with a trailer or driving at high altitudes in combination with fuel quality are factors that could affect the car's fuel consumption.
