Your fuel consumption will vary

Fuel consumption ratings show the fuel consumption that may be achieved with a properly maintained vehicle driven with fuel efficiency in mind. The ratings provide a reliable comparison of the fuel consumption of different vehicles. However, no laboratory test can simulate all combinations of conditions that may be experienced by drivers. Your vehicle’s fuel consumption will vary from its published fuel consumption ratings, depending on how, where and when you drive.

The following factors affect the fuel consumption of your vehicle: acceleration, driving speed, the age and condition of your vehicle, temperature, weather, traffic and road conditions, the drivetrain, and the powered accessories (like air conditioning) installed on your vehicle. In addition, small variations in vehicle manufacturing may cause fuel consumption differences in the same make and model, and some vehicles do not attain optimal fuel consumption until they are “run in” for about 6,000 to 10,000 km.

Hybrid vehicles are particularly sensitive to driving conditions and behaviours and can exhibit greater variations in fuel consumption than conventional vehicles. Moderate differences in how, where and when you drive can have a significant impact on how much your hybrid’s gasoline engine is used.

Published ratings are a useful tool for comparing vehicles before you buy, but keep in mind that they’re based on standardized tests and may not accurately predict the fuel consumption you will get on the road.

Adopt fuel-efficient driving techniques to reduce your fuel consumption and carbon dioxide emissions by as much as 25%.
