TrueDelta Reviews the Real Gas Mileage of the Dodge Durango

Dodge Durango Real Gas Mileage: Cons
Year	Comment
2006	Like the Durango SRT's key strength, it doesn't require the skills of Sherlock Holmes to detect the Dodge's primary weakness: its fuel economy. In the EPA's tests, the Durango SRT managed only 13 mpg city and 19 mpg highway. The trip computer typically reported 12 mpg in my suburban driving. Driving the brute like a Prius bumped the number all the way to 15 mpg. On the highway I observed as high as 20 mpg, again in line with the EPA rating. The Durango R/T manages a bit better, 14/22, putting it not far off the Explorer Sport's 16/22. But a Mercedes-AMG GLS63, with turbochargers to pack more fuel-air mixture into its cylinders, can guzzle even more than the Durango SRT: 13/17. If you want an ultra-quick three-row vehicle with outstanding fuel economy, you're currently limited to the Tesla. Though perhaps the plug-in hybrid Volvo XC90 T8's 26/30 is good enough? see full Dodge Durango review

2007	4dr SUV 235-horsepower 4.7L V8 5-speed automatic AWD	Mileage is actually pretty good for an 8 person hauler, but compared to our old 5 passenger SUV we are giving up 2-3 MPG. Will know more after a couple more fill-ups for sure. see full Dodge Durango review
2006	4dr SUV 335-horsepower 5.7L V8 5-speed automatic AWD w/low range	14-16 mpg city,20 highway but for size not unexpected and better than some others in this class see full Dodge Durango 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
