Fuel consumption and CO2
emissions
Fuel consumption and CO2 emissions can be
affected negatively by several causes.
Examples of reasons for increased fuel consump-
tion are as follows:
•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 increa-
ses.
•High speed results in increased wind resis-
tance.
•Fuel quality, road and traffic conditions,
weather and the condition of the car.
A combination of the above-mentioned examples
can result in significantly increased consumption.
Consumption is higher and power output lower
for fuel with an octane rating of 91 RON.
NOTE
Extreme weather conditions, driving with a
trailer or driving at high altitudes in combina-
tion with fuel quality are factors that consider-
ably increase the car's fuel consumption.
