New Testing for Vehicle Fuel Consumption

Does your car use more fuel than you thought it would ?

How much fuel a vehicle uses can greatly impact its operating costs and ultimately influence our decision to purchase one vehicle over another.

For this reason Natural Resources Canada obligates car manufacturers to test their vehicles and to clearly display the results on the vehicle window sticker so we can make informed decisions.

To further assist the consumer, Natural Resources Canada has introduced new testing procedures starting with the 2015 model year that more accurately simulate day-to-day Canadian driving.


From 2 cycle to 5 cycle testing


Up to 2014 vehicles have had a 2 cycle test consisting of 1) a city test 2) a highway test

Starting with the 2015 models the 5 cycle test adds 3 more tests to supplement the existing 2 tests. 3) cold temperature operation test 4) air conditioning test 5) high-speed/quick acceleration test

The new 5 cycle test offers a more realistic result that is more like our actual “on road” fuel consumption. As a result, there has been an increase in fuel use rating of between 10-20 percent. This is not because vehicles have become less efficient but because the testing has become more accurate. The same model will show different fuel usage for 2014 compared to 2015 because of the new test.

Below are ratings with the new and old system for the same vehicle as they appear on the government website

Model Year 2014

Model Year 2015


It’s important to remember that these ratings represent the same vehicle and that when comparing models for fuel efficiency you must compare the same ratings. Either 2014 or prior or 2015 to other 2015 ratings.

While the new testing system will give fuel consumption results that are more true to life, remember that we all have different driving styles that will affect our actual fuel consumption. So use the ratings to compare one vehicle to another while being aware that you might still get a different result depending on how you drive.
