Ford C-MAX Real Gas Mileage: Pros
Year	Comment
2013	The Ford C-MAX's fuel economy is at once the #1 reason most people will buy a C-MAX, but also the model's greatest shortfall. The EPA ratings are an impressive 47 mpg city, 47 highway. In real suburban driving we (and many owners) observed trip computer averages of 33 to 40, with an overall average of 35.8. Go easy on the gas and initiate braking early enough to fully recoup kinetic energy, and low to mid 40s can happen. But 47 is a stretch. There are two ways to look at this. On the one hand, the C-MAX isn't coming close to its EPA ratings. Odds are Ford will have to make an adjustment and credit past buyers for the difference, Hyundai-Kia style. (Which actually might be a reason to buy one before this happens.) On the other hand, even 36 mpg is about 8-12 miles-per-gallon better than similarly functional non-hybrid vehicles, including the related Ford Escape. Efficiency is supported by excellent, highly configurable instrumentation. I personally opted to view a tach (rare in a hybrid), driving style ratings, and average mpg. A "brake coach" lets you know after each stop what percentage of kinetic energy was regenerated. In hybrids, this has a large impact on mpg than how hard you accelerate (more on this below). The C-MAX is also offered as an "Energi" Plug-in Hybrid rated to cruise 21 miles on electricity alone. see full Ford C-MAX review

2013	4dr Hatch 141-horsepower 2.0L I4 Hybrid CVT FWD	With some care, it is not too hard to surpass the revised EPA estimates of 44 city / 39 highway. It particulary shines in city and suburban driving where you can crest 50 mpg on some short trips. In mixed driving, we match the EPA estimate of 40 MPG without paying much attention. While not as great as the Prius, this efficiency was certainly a step up for us and the difference in fuel costs over a year between the C-Max and Prius was not worth the shortcomings we found in the Prius (particularly poor handling and uncomfortable seats). see full Ford C-MAX review

2013	4dr Hatch 141-horsepower 2.0L I4 Hybrid CVT FWD	On the down side for fuel economy, cold weather does a number on the MPG as is reported with other hybrid. On short trips (4 miles or less) on a cold start in cold weather with the heater going, expect low 20s for your MPG. This is mitigated over longer trips once the engine has warmed up, but we still get 1-3 MPG under our usual in cold weather for longer trips. see full Ford C-MAX 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

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
