Not great compared to a Honda Civic, but thats like comparing an F-18 to a Piper Cub. LR4 is very throttle sensitive. A lighter foot improves mileage considerably. Considering the size & capability of this vehicle, mileage is reasonable. see full Land Rover LR4 review

Horrible, and its not just the price of the pump that is the problem, its the range. City driving gives me 11-12 mpg....but despite the 23g tank specs, after the fuel warning light come, I have rarely filled my tank up more than 19 gallons....Usually after only @230-240 miles.....you will be going back to the pump frequently..,Pure freeway driving, you get up to around 17 mpg on the flats...(dont believe the computer, its always about 1.5mpg too optimistic ). If only they brought in the diesel, or had a bigger useable fuel tank.... see full Land Rover LR4 review

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

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

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

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
