Chevrolet SS Real Gas Mileage: Cons
Year	Comment
	My mention of a $1,300 gas guzzler tax foreshadowed this "why not." If you want a fuel-efficient car, you probably don't want a big, V8-powered sedan. But even compared to the Dodge Charger R/T the SS is a guzzler. This is partly because the very small number sold doesn't justify an upgrade to GM's latest engine and transmission technology, which includes variable valve timing, cylinder deactivation, and eight-speed automatic transmissions. These technologies enable the Charger R/T to earn EPA ratings of 16 mpg city, 25 mpg highway, while the SS can only manage 14/21 with a six-speed automatic or 15/21 with a six-speed manual (which skips from first to fourth under light throttle). In my real-world driving, the trip computer usually reported an average around 16 or 17 in the suburbs (20 if I drove with a very light foot) and MAYBE 24 on the highway. The trip computer in the Dodge reported averages that were usually higher by a couple MPG, but keep its engine in V4 mode (i.e. no lights to stop for) and the average can reach 30. see full Chevrolet SS review

2017	4dr Sedan 415-horsepower 6.2L V8 6-speed manual RWD	Wow, really, really bad. All the reviews you may have read about the fuel economy are dead on. You can optimistically get 24 on the freeway and low teens city. Then again you are NOT buying this car for fuel economy. see full Chevrolet SS review

2008	4dr Sedan 160-horsepower 2.3L I4 5-speed automatic FWD	MPG up to 34 hwy, no less than 25 in heavy traffic. 17 gal tank gives you around 500 mile range between gas stations. see full Mercury Milan review
2007	4dr Sedan 160-horsepower 2.3L I4 5-speed automatic FWD	The economy is amazing and not compromised. see full Mercury Milan review
2007	4dr Sedan 160-horsepower 2.3L I4 5-speed automatic FWD	I can carry my family, in comfort, for long trips and still get 30mpg+. Around town driving returns 23+ mpg. This mileage is within 2-3 mpg of the smaller 2003 Focus we replaced. see full Mercury Milan review
2006	4dr Sedan 160-horsepower 2.3L I4 5-speed automatic FWD	I have seen as high as 34.5 mpg at 57mph. see full Mercury Milan review

2006	4dr Sedan 160-horsepower 2.3L I4 5-speed automatic FWD	We consistently get around 30 MPG - and this is computed from amount of fuel and miles travelled, not from the "trip computer." This is a darn nice-size car to deliver that kind of fuel economy. see full Mercury Milan review

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
