Buick Encore Real Gas Mileage: Pros
Year	Comment
2013	With front-wheel-drive, the Encore earns EPA ratings of 25 mpg city and 33 mpg highway. Add all-wheel-drive (as on the tested car) and these figures drop to 23/30. Given the Encore's small size and marginal power output, better might be expected. The BMW X1, with another 102 horsepower, somehow manages 22/33 on the EPA test cycle. But the BMW's ratings seem a bit iffy. I had a much easier time meeting and exceeding the Buick's EPA ratings. At a steady 70 on the highway I averaged over 31. In suburban driving the trip computer regularly reported averages in the low 30s, even 35. To average over 30, though, you can't have too many stops or too heavy a foot. Put the pedal down hard, and the small four-cylinder engine's turbo will enable it to gulp air--and fuel--like a much larger one. Drive with little care for fuel economy, and 25 will happen. Which is still better than the EPA rating. The Tucson is among the oldest designs in Hyundai's line, and doesn't have the firm's latest engine technology. Consequently, its EPA ratings are a dismal (for a compact, 176-horsepower vehicle) 20/27. The current compact crossover champ, the Mazda CX-5, manages just a little better than the Encore, 24/30. see full Buick Encore review

Buick Encore Real Gas Mileage: Pros

2013	4dr SUV turbocharged 138hp 1.4L I4 6-speed shiftable automatic AWD	The almost 40 mpg on the highway makes the Buick Encore the most efficient, real world, all wheel drive gasoline sedan or CUV available. The engine torque from the turbo makes output low in the operating range on low 87 octane. see full Buick Encore review

2009	4dr SUV 240-horsepower 3.0L V6 6-speed automatic FWD	Coming from a Trailblazer, we like the average of 21-22 MPG in mixed driving, as were used to about 17 MPG. Fuel economy climbs toward the rated 26 MPG the more highway driving we do. see full Mercury Mariner review
2007	4dr SUV 200-horsepower 3.0L V6 4-speed automatic AWD	For the first almost three years after we got the car, it gave 21+ mpg in town & 24+ mpg on the road. see full Mercury Mariner review
2005	4dr SUV 153-horsepower 2.3L I4 4-speed automatic AWD	For an SUV with a 4cyl and 4wd I get avg of 22 MPG mixed city and highway. I usually get 23-26 on freeway only. This is good. see full Mercury Mariner review

Mercury Mariner Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2007	4dr SUV 200-horsepower 3.0L V6 4-speed automatic AWD	For some reason when new Michelin All Terrain tires with Nitrogen air replaced the Champions from the factory, it plummeted to 17 & 20 mpg. No explanation from Michelin, Costco or Ford/Mercury - they have no idea why. see full Mercury Mariner review
