The Canadian fuel consumption ratings and the US EPA are quite different for my Corolla. Just for highway...

Canada - 5.6L/100km highway, 50mpgImp, or 42mpgUS
USA - 6.7L/100km, ~42mpgImp or 35mpgUS

The city ratings have about the same kind of spread. That is quite a variance IMO. Of course I aim for the Canadian ratings as they are more challenging and I usually meet them occasionally beat them, but I have to drive with fuel economy in mind to do it. The US EPA ratings..I could match that driving like a hooligan. I can get those kind of numbers with the LeSabre.

In looking at some of the ratings for the same car from the UK, they more match the US EPA ratings. The testing must have some huge variances between the two countries. I don't completely understand what is happening.

The Mazda 3 is another car that has large differences, I am sure there are a lot more out there.
