Chevrolet Sonic Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2013	4dr Sedan turbocharged 138hp 1.4L I4 6-speed manual FWD	The fuel economy is excellent on this car as long as you are not on the pedal too heavy. Freeway (70-75 mph) mileage is around 40 to 42 mpg. Rural highway (55-62 mph) 42-46 mpg. The worst mpg i have every experienced is 36.5. This was mostly in town with the AC on. see full Chevrolet Sonic review
2012	4dr Sedan turbocharged 138hp 1.4L I4 6-speed manual FWD	Have never got below 37.7 miles to the gallon. I do drive conservatively but even when my husband who drives significantly more aggressive the gas mileage has been excellent see full Chevrolet Sonic review
2012	4dr Sedan 138-horsepower 1.8L I4 6-speed shiftable automatic FWD	I had a Choice between My Current Car, a Kia Rio , a Ford Focus and Mazda 3. Between ALL these only the Sonic was a Certified Pre-Owned Vheicle and the others were not. The Fuel economy was ALMOST the Same..but i thought the Sonic had faired A Tad bit better. see full Chevrolet Sonic review

Mercury Milan Real Gas Mileage: Cons
Year	Body/Powertrain	Comment
2008	4dr Sedan 160-horsepower 2.3L I4 5-speed automatic FWD	Hyundi Sonata with similar size engine and a 5-speed automatic delivers 22/32. Malibu with a 2.4 and a 6-speed delivers 22/32. Focus/Milan with a 2.3 and 5-speed auto 20/28. Initial freeway driving is consistent in the 28-30 mpg range. Competitors better. see full Mercury Milan review
