If you were to go to natural resources Canada and check the fuel consumption figures you will find that the domestics are actually get very good mileage

Based on the Government Testing the domestics are not as good as the Civic, but better then the mazda 3's on a consumption basis.
Because It is not clear that they are using Imperial gallons. I think most people who look at that ad. Will think that the cars do better gas mileage than they actually do. The Domestics are the worst when comes to gas mileage. Which is why they use those figures. Who to say what they intention are. I can only speculate.
I don't see how the add can be considered deceiving as the info is in agreement with the government published data. It has always been accepted by people of my generation that if you see a mileage published in a Canadian paper that it be in imperial unless it Clearly states US MPG They could also advertise the Impala As getting 40 MPG as that is the Highway mileage for one Impala Model. While the domestics have a Lot of things they need to improve ( I wouldn't own an Aveo if you gave it to me) Clearly fuel consumption is one area where they are making great improvement over a decade ago. When the Ford Focus gets a rating of 50 MPG while the Niisan versa gets a 47 mpg highway rating,(*Again from the NRC) then its time for you to reconsider such a sweeping statement as "The Domestics are the worst when comes to gas mileage"
