231Driving and the environment
Avoid carrying unnecessary loads
The lighter the vehicle, the more economical and ecological the driving
style. For example, an additional weight of 100 kg will increase fuel con-
sumption up to 0.3 l/100 km.
Remove any unnecessary objects or loads from the vehicle.
Remove optional equipment and unnecessary accessories
The more aerodynamic the vehicle, the lower the fuel consumption. Option-
al equipment and accessories (such as roof racks or bike carriers) reduce
the aerodynamic benefits of the vehicle.
Therefore, we recommend you remove all optional and unnecessary equip-
ment and racks, especially if you intend to drive at high speeds.
