Show answer & explanation
Correct answer: Avoid carrying unnecessary weight..
The more extra weight is in your vehicle; the more fuel you use. Using a roof rack or a roof box increases wind resistance and this also increases fuel consumption ? by as much as 15%. Remove roof racks and roof boxes when not in use.
