I bought the vehicle new from Shaw GMC in Calgary. the year is 2011 AWD SLT. The General Manager of the dealership has been notified and he "guaranteed" the economy would improve after 10,000 km. I now have over 14,000 km. No change has happened. I had just brought the car in for a recall on the cam actuator valves. I did not expect 41. I did expect it to be around 36-37 MPG. I did think that after trading a VW Jetta TDI to get fuel economy that is comparable but has a little more room. I never expected OVER 30% less the offered on paper and on radio adds.

I understand your concern. What seems to happen is that Canadian fuel ratings are way wrong!

I'm really surprised to see that while American EPA rates the GMC Terrain FWD 4 cyl. at 32 MPG highway, the Canadian counterpart rates it at 46 MPG highway, 31 MPG city.This just doesn't make sense. The way the Canadian gov. measure fuel-economy is probably obsolete.

Look yourself:

Please note: Canada measures gas mileage with Imp. gallons, not US gallons. So that would explain the difference. Also, take into account that they test the vehicle in ideal condition (no acceleration, steady 97 km/h speed, flat road, no wind). These are not real-world condition.

Well, I'm sorry to tell you don't have much of a case here. The Canadien gov. gives figures in IMP.GAL or METRIC (Canada is still part of the Commonwealth). The salesman gave you a canadian measure which is 42 Mile per Imp. Gal. Convert this to US gallons, it is about 34.9 MPG. That is close to your 28 MPG you are reading from your car, right? So, the salesman was right. If your car was displaying 38 Imperial MPG instead of 28 US MPG, would you be happy?

Your only case here is why the federal gov. is still using British MPG measures and is not using only metric measures which are less confusing. At the pump, we still buy liters, right?

With some common sense, you should never have thought that the car would do 42 Mile per Us.Gal, that is a hybrid-class fuel consumption that the smallest cars don't even achieve. With the smallest amount of research you would have figured it out.

I hate to be an a-hole but that's what it all comes down to, common sense. No way can a SUV such as the Terrain get 42 MPG's, especially with the type of powertrain it has. I doubt even a Prius can get that.
