TrueDelta Reviews the Real Gas Mileage of the GMC Terrain

GMC Terrain Real Gas Mileage: Pros
Year	Comment
2018	Diesel engines burn far cleaner than they used to. But even the best retain disadvantages. Diesel fuel is nasty, greasy stuff, with a feel closer to motor oil than gasoline. Spill any on your hands, clothes, shoes, or car while filling up and it doesn't evaporate away like gas does. Also, the GMC Terrain's exhaust stinks, especially when its engine is cold. You might want to have the fresh air vent closed if you'll be reversing after starting up the vehicle. Given these disadvantages, a diesel better deliver strong EPA fuel economy ratings, and this four-wheel-drive GMC does: 28 mpg city, 38 mpg highway. (Dropping 4WD adds another mpg to the highway rating.) The Jaguar F-Pace diesel lags, with 26/33, as might be expected given its larger (2.0- vs. 1.6-liter), considerably more powerful (180- vs. 137-horsepower) engine. The RAV4 Hybrid is more economical in city driving, with an EPA rating of 34 mpg, but well behind in highway driving, with an EPA rating of 30. This is typical of diesel vs. hybrid comparisons, as hybrids are designed to recoup energy otherwise burned off by the brakes and thus deliver the largest bump in city driving. Even more than with most vehicles I test, the Terrain diesel's real-world fuel economy varied dramatically based on driving style and conditions. In the suburbs, trip computer averages ranged from 25 to 40 mpg, with most results around 30. On the highway, the trip computer reported low 40s in one direction, then low 30s in the other (on two different days, with no especially strong wind on either). In a suburban test drive of the Toyota RAV4 Hybrid, the highest trip computer average I could achieve was 38 mpg. Quite good for a compact crossover, and nearly even with the best suburban average I observed in the Terrain diesel. Compared to a Terrain with the standard gas engine, the diesel rates four mpg high in the city and ten mpg higher on the highway. Compared to the Terrain with its base gasoline engine, the Jeep Compass rates lower in the city (22 vs. 24 mpg) but higher on the highway (30 vs. 28 mpg), so gas-to-gas they're about even. see full GMC Terrain review

GMC Terrain Real Gas Mileage: Cons
Year	Comment
2010	On a positive note, the larger V6 earns the same EPA fuel economy ratings as the old one. On a less positive note, it also earns the same fuel economy ratings as the much larger, 4,850-pound Acadia: 16 city, 23 highway. In suburban driving the trip computer reported high teens to low twenties, a few mpg below lighter, more compact competitors. The four-cylinder gets 22/32 with FWD, 20/29 with AWD, but many owners have failed to approach these numbers in the real world. see full GMC Terrain review

2012	4dr SUV 182-horsepower 2.4L I4 6-speed shiftable automatic AWD	Although I have never seen this truck get the estimated fuel economy it boasts about in advertising, considering the shear mass of it and it's breadbox front end, with the I4 the fuel economy is very good considering it is a heavy little beast with AWD. I can average 700 kms. out of a tank of fuel no problem and on longer jaunts have seen it break 800 kms. If you are one of those people who complain about fuel consumption in this truck- you should have bought a Prius... because for what it is, it is exceptional on fuel. Try a different brand of fuel for a while, some brands have more additives and burn quicker. see full GMC Terrain review

2015	4dr SUV 301-horsepower 3.6L V6 6-speed shiftable automatic AWD	Fuel economy, for a vehicle over 4,000lbs, and a 300hp V6 engine, is going to be low. But at between 15-18mpg, for suburban driving, it seems a bit low. I wanted to the V6 so it would not struggle, and I did that knowing the MPG's were not great, but I hoped it would be better on the highway. What I found most disappointing, was that with the V6, you don't get an "economy" switch. The 4 cylinder version does, but not the V6. Why does this matter? Because with a V6, with much more power than a 4 cylinder, using economy mode would not feel bad. On the Terrain, with the 4 cylinder you are starting with less, so taking away from less isn't alwyas good. But taking away from the V6, would not be as impacting. see full GMC Terrain review

2006	The performance of these cars is not without an obvious tradeoff. In EPA tests, the Mustang GT manages only 15 mpg city, but 25 mpg highway, with the manual transmission. With the optional six-speed automatic, the car can go a mile farther per gallon in the city. The Audi rates a little better in the city, but worse on the highway: 16/23. In my real-world suburban driving, the Mustang's trip computer most often reported averages in the 16-17 range. With a light foot I could nudge the average over 20, and even as high as 24, but what's the point of driving a Mustang GT like you would (or at least should) a Prius? On a 70-mph highway, with the big V8 spinning under 2,000 rpm in top gear, the trip computer reported a fairly impressive (for such a large, powerful engine in a fairly heavy car) 28 mpg. But if you want decent fuel economy in either car, you'll have to ditch the V8. The new EcoBoost four-cylinder achieves 22/31 with a manual transmission and 21/32 with the automatic. The Audi manages similar figures with a 220-horsepower 2.0T four-cylinder engine, but 17/26 with the manual and 18/28 with the automated dual-clutch transmission and the S5's supercharged V6. see full Ford Mustang review

2008	2dr Coupe 300-horsepower 4.6L V8 5-speed manual RWD	For a V8, I still get great fuel economy. I average 21mpg with combined city & highway, about 75% city. Only long highway trips, I average 27mpg at 70mph. see full Ford Mustang review
2007	2dr Coupe 300-horsepower 4.6L V8 5-speed manual RWD	Surprisingly, the V8 gets about 23-25 MPG highway driving IF you behave; better than my SUV. The Stang is my choice for my frequent 800+ miles trips once or twice per month. see full Ford Mustang review

Ford Mustang Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2013	2dr Coupe 420-horsepower 5.0L V8 6-speed manual RWD	19.6 MPG under tame driving (read: shifting at 2200rpms), 10.2 under agressive driving. see full Ford Mustang review
2012	2dr Coupe 305-horsepower 3.7L V6 6-speed manual RWD	I was hoping for a bit better than the 24 I'm getting in commuting duty. Car still has less than 2000 miles, so it may improve w/ summer blend gas and a more broken in engine. If I could get 26 I'd be much happier, but I'm not counting on it see full Ford Mustang review

2009	2dr Coupe 300-horsepower 4.6L V8 5-speed manual RWD	The GT/CS is surprisingly economical; GT500 is a profligate gas gobbler - but who really cares? see full Ford Mustang review
2008	2dr Convertible supercharged 500hp 5.4L V8 6-speed manual RWD	Premium fuel is expensive and mileage with a blown 5.4 is not stellar. I would not recommend this as a daily driver but it makes a hell of weekend and evening toy. see full Ford Mustang review
2008	2dr Coupe supercharged 500hp 5.4L V8 6-speed manual RWD	12 mpg city is poor, hi way mpg of 22 is not too bad see full Ford Mustang review
2007	2dr Coupe 210-horsepower 4.0L V6 5-speed manual RWD	I checked mileage carefully, hoping it was possible to get better than 18-20 m.p.g.- not likey in everyday driving. see full Ford Mustang review
