TrueDelta Reviews the Real Gas Mileage of the Chevrolet SS

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

Year	Body/Powertrain	Comment
2013	4dr SUV 325-horsepower 3.7L V6 7-speed shiftable automatic AWD	Could be better by today's standards see full Infiniti EX review
2010	4dr SUV 297-horsepower 3.5L V6 5-speed shiftable automatic AWD	love the V6 power but the EPA MPG is worrisome see full Infiniti EX review
2010	4dr SUV 297-horsepower 3.5L V6 5-speed shiftable automatic RWD	OK This is NOT a car to buy if MPG is important although I am getting over 23 MPG avg. It is a POWERFUL car with a great drive train ready like a race horse at the gate to giddy up and it does when you need it on premium recommended fuel....in spades. I don't drive enough to care about fuel economy all that much. Not an econobox. see full Infiniti EX review
2009	4dr SUV 297-horsepower 3.5L V6 5-speed shiftable automatic AWD	17MPG in the city is a little disappointing for a vehicle with such finesse and reputation. I would guess Infiniti would cater to the masses with styling, performance and a little more economy. Not asking for miracles but I'm sure they could squeeze out 3 or 4 more MPG with the same 3.5L V6 see full Infiniti EX review
2008	4dr SUV 297-horsepower 3.5L V6 5-speed shiftable automatic RWD	Uses premium fuel. see full Infiniti EX review
2008	4dr SUV 297-horsepower 3.5L V6 5-speed shiftable automatic RWD	I average about 20 miles per gallon on premium fuel - with a mix of street and highway driving. I typically get 16 mpg in the city and 24 on the highway. Some of this is attributable to the 5 speed transmission on the car, which favors acceleration to economy. I imagine the 7 speed transmission should help the car get better highway economy. see full Infiniti EX review
2008	4dr SUV 297-horsepower 3.5L V6 5-speed shiftable automatic AWD	Expensive to keep fuelled given poor gas mileage and costs of premium fuel. Number 1 reason I am thinking of switching to another car. see full Infiniti EX review
2008	4dr SUV 297-horsepower 3.5L V6 5-speed shiftable automatic AWD	Slightly low if driving mostly city. see full Infiniti EX review
