Hyundai Genesis Coupe Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2013	2dr Coupe turbocharged 274hp 2.0L I4 6-speed manual RWD	I average around 26 mpg in mixed driving, with a moderately heavy right foot. On a long, flat roadtrip I averaged ~32 mpg with speeds ranging from ~70-80 mph. Even in city driving and stop-and-go traffic I rarely dip below 20 for a trip. see full Hyundai Genesis Coupe review
2010	2dr Coupe turbocharged 210hp 2.0L I4 6-speed manual RWD	Very good, better than a Rx-8, not as good as a Civic Si. see full Hyundai Genesis Coupe review

Hyundai Genesis Coupe Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2011	2dr Coupe turbocharged 210hp 2.0L I4 5-speed shiftable automatic RWD	For a 3400 pound car the fuel economy is really pretty good considering I have a turbo which I keep spinning up. The EPA numbers did not enter into my choice, however the manufacturer advertises 20 - 30 mpg which is a bit of a fantasy. A rating of 19 - 27 would be reasonable and kept a lot of people from complaining on the forums. I have personally seen 28 / 29 mpg on the highway so the 30 mpg is possible, but not practical. For a heavy turbo-charged RWD car my mileage is pretty good; just not what was advertised. see full Hyundai Genesis Coupe review
2011	2dr Coupe turbocharged 210hp 2.0L I4 6-speed manual RWD	For a 4 cylinder cat the MPG is not what I expected. see full Hyundai Genesis Coupe review
2010	2dr Coupe 306-horsepower 3.8L V6 6-speed shiftable automatic RWD	Highway fuel economy is decent for a large V6, but city fuel economy, especially in winter, struggles to break 13mpg. see full Hyundai Genesis Coupe review
2010	2dr Coupe 306-horsepower 3.8L V6 6-speed shiftable automatic RWD	Not terrific see full Hyundai Genesis Coupe review
2010	2dr Coupe turbocharged 210hp 2.0L I4 5-speed shiftable automatic RWD	Fuel Economy is my ONLY dislike of the Genesis Coupe. I was excepting less gas consumption especially in city driving. see full Hyundai Genesis Coupe 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
