Fuel consumption and CO
emissions
Fuel consumption and CO emissions can be
2
negatively impacted by a number of factors.
Examples of causes of increased fuel consump-
tion include:
If the car is equipped with extra equipment
•
that affects its weight.
Driving style.
•
If the customer chooses wheels other than
•
those mounted as standard on the basic ver-
sion of the model, this could increase rolling
resistance.
High speed causes increased air resistance.
•
Fuel quality, road and traffic conditions,
•
weather and the condition of the car.
A combination of the examples above could
increase consumption considerably.
NOTE
Extreme weather conditions, driving with a
trailer or driving at high altitudes, in combina-
tion with poorer fuel quality than recom-
mended, are factors that considerably
increase the car's fuel consumption.
