16 MPG combined isn’t going to win any fuel-sipping awards, but that’s hardly the point of the 2017 Chevrolet SS. This is a rear-wheel-drive, V8-powered sedan that prioritizes performance above all else. Its buyers, typically driving enthusiasts who appreciate a naturally aspirated engine and a manual transmission option, understand the compromise and willingly accept it for the exhilarating driving experience it delivers.

City and highway performance

The EPA estimates for the 2017 Chevrolet SS break down to 14 MPG in the city and 22 MPG on the highway. The relatively low city MPG reflects the engine’s displacement and power, requiring more fuel during stop-and-go driving. The highway number, while not stellar, is more respectable and achievable during relaxed cruising, thanks to the six-speed automatic transmission. Keep in mind that aggressive driving, which the SS easily encourages, will significantly reduce both figures.

Annual fuel cost

According to the EPA, the annual fuel cost for the 2017 Chevrolet SS is $3,600. This estimate is based on driving 15,000 miles per year and using national average fuel prices. Individual fuel costs will vary depending on driving habits, local fuel prices, and the type of fuel used. The SS requires premium gasoline (91 octane or higher) to deliver its advertised power and efficiency, which further contributes to the higher running costs. Anyone considering this car needs to factor in this premium fuel requirement when budgeting.

Real-world expectations

While the EPA provides a standardized testing methodology, real-world fuel economy can differ significantly. Expect to see figures slightly below the EPA estimates, especially if you frequently indulge in the car’s performance capabilities. Achieving the 22 MPG highway figure requires conscious effort and restraint. In mixed driving, many owners report averaging closer to 15 MPG.

How it compares

The 2017 Chevrolet SS exists in a unique niche. A closer competitor is the Dodge Charger R/T (often miscategorized). The Charger R/T with its 5.7L V8 achieves slightly better EPA numbers around 19 MPG combined. A BMW 340i of the same year, a smaller and lighter car with a turbocharged six-cylinder, manages around 25 MPG combined, a significant improvement. The related Pontiac G8 GXP, a predecessor to the SS that used a similar engine, achieved similar MPG figures when new. This comparison illustrates the trade-off performance enthusiasts must accept: pure naturally aspirated V8 power comes at a fuel economy cost. Check all Chevrolet fuel economy data.

Tips to maximize efficiency

While the SS isn’t about outright fuel efficiency, there are steps you can take to minimize consumption. First, resist the urge to constantly explore the upper reaches of the rev range. The 6.2L V8 is happiest when leaned on, but gentle acceleration and cruising when appropriate makes a real difference.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel. Check your tire pressures at least monthly, especially during temperature changes.

Avoid unnecessary idling. Modern engines don’t need to warm up for extended periods. If you’re stopped for more than a minute, turn off the engine. The six-speed automatic transmission saps energy, so avoid aggressive acceleration from stoplights.

Regular maintenance is critical. Keep the engine properly tuned, with fresh spark plugs and clean air filters. A well-maintained engine runs more efficiently and burns fuel more cleanly.

Consider a less aggressive driving style. Smooth acceleration, consistent speeds, and anticipating traffic flow can significantly improve your fuel economy without sacrificing all of the fun of driving a powerful RWD sedan.
