Default Crappy fuel economy

Is anyone else getting horrible mpg? I was sold my Terrain at 41 mpg highway. I can barely get 29.

Where did you read or hear 41 mpg? Even a Cruze Eco wouldn't beat that.

The official numbers are 22 mpg city, 32 mpg highway, and that is without All-wheel-drive. And on top of that, some said GM has inflated the numbers.

That is what I was told by the dealer as well as the original sticker on the car, which I have in my possession.

You could probably achieve that downhill, with the engine off.

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.

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.
