So I now use the Euro Urban and Combined numbers to compare to US EPA Cityand Highway, not saying that this is 100% accurate as many of the Urban numbers are lower but think the Combined number will approximate U.S. EPA Highway fairly well.

Of course as it is with EPA numbers many drivers of GM products get better than the rating in real world driving, so as with any number from standardized test "your mileage may vary".

Thanks for the feedback!

Did you get a chance to look for the GM/Vauxhall(Opel) machines above 52 mpg(Imperial) combined cycle? Did you find out how far up they go?

You might find the Fords above 52 mpg(Imperial) interesting also. The Duratorq is an interesting and apparently capable engine.
