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

2003	4dr SUV 275-horsepower 4.2L I6 4-speed automatic 4WD w/low range	I average about 16 MPG in town and 20 on free way on a good day (depends on trafic and road altitude changes, sometimes it was better than 20mpg). see full GMC Envoy review
2002	4dr SUV 270-horsepower 4.2L I6 4-speed automatic 4WD w/low range	I cannot seem to get above 16 mpg. I wish I had better fuel economy. see full GMC Envoy review
2002	4dr SUV 270-horsepower 4.2L I6 4-speed automatic 4WD w/low range	Stinks for a 6 cylinder. see full GMC Envoy review
