Confused about mileage

[bandit86]

Brand new vw Jetta, on vw.com, on american site lists mileage as 30/42. On the Canadian site it lists it as 6.7 and 4.6l/100km whic converts to 35/51 mpg and on the dealers lot the window stickers say 40/59. Wtf?

Hi bandit86,
1. Canadia uses the older EPA cycles which show higher mpg than current US numbers.
2. Canadia use imperial gallons, bigger than measly USA gallons, which shows even higher mpg.

EPA says 30/42: Fuel Economy of 2012 Volkswagen Jetta

X2 on Canadia being wierd.

This is why we crash things into Mars and run Air Canada jets out of fuel, mid-flight.

Canada uses imperial mpg? That's is bloody retarded! But even then the numbers don't convert properly,

Wouldn't it be worth it just for the better mileage for the US to declare war on Canada and immediately surrender?

Taken from Transport Canada website. #1 and #2 are obvious so maybe #3

Why do Canadian fuel consumption ratings differ from the US ratings?

There are a number of reasons why the Canadian fuel consumption ratings, as stated in the Fuel Consumption Guide, might differ from the numbers posted in the United States Fuel Economy Guide.

Canadian or imperial gallon versus U.S. gallon
The Canadian gallon is larger than the U.S. gallon, so the Canadian fuel consumption ratings provide higher miles per gallon estimates. The Canadian Fuel Consumption Guide uses Canadian or imperial gallons as the unit of measurement for volume. The U.S. Fuel Economy Guide uses the U.S. gallon. 1 Canadian gallon = 0.8327 U.S. gallons and 1 Canadian mpg = 1.2 U.S. mpg.

Testing and calculation differences
Effective for the 2008 model year, the U.S. Environmental Protection Agency (EPA) has added three additional test cycles to its original two cycles of city and highway testing (See 5-cycle testing). As such, their fuel economy calculations are different in order to incorporate the results of the additional tests. These changes have resulted in differences between the Canadian and U.S. (EPA) numbers. Also note that in Canada, we talk about "fuel consumption" while in the U.S., they refer to "fuel economy".

Correction and adjustment factors
In addition to the testing and calculations differences between Canada and the U.S., the correction and adjustment factors also differ. For example, the U.S. EPA applies a correction factor of 22% to their highway fuel economy test estimates to better approximate real-life driving conditions, whereas in Canada, a 15% correction factor is used.

Therefore, both the U.S. EPA fuel economy ratings and the fuel consumption ratings in the Canadian Fuel Consumption Guide can be considered "correct" as they pertain to vehicles in their respective countries. However, the inherent differences do not allow cross-border comparisons. The ratings are only useful when comparing the fuel efficiency of various vehicles within the country in which you reside.

I never ever go by the Canadian Government fuel economy numbers. They are ridiculously optimistic. I am amazed that they have not yet changed the testing methods to match the EPA methods.

Jakobnev, we did have a war with you in 1812. We kicked your ass on land and you kicked our ass on the sea, so we teach our kids that we won and you teach your kids that you won!

...where was the "Air Farce" when we really needed them (ha,ha), flying a "kite"?

[mechman600]

Don't laugh! Our air force has a total of 77 fighter jets (F-18s). Ok, feel free to laugh. People are up in arms because we have ordered 65 more (F-22s). That's okay - if we get in trouble we will just call you guys. You'll come and help, right? Right?....
