22 MPG combined isn’t going to win any awards, but the 2022 Porsche 718 Cayman S isn’t designed for hypermiling. This is a focused sports car built for driving pleasure, and its fuel economy is simply a fact of life for those who crave its razor-sharp handling and potent turbocharged engine. Buyers aren’t prioritizing fuel efficiency above all else; they’re seeking an engaging driving experience, and the Cayman S delivers that.

City and highway performance

The EPA estimates for the 2022 Porsche 718 Cayman S equipped with the 7-speed automatic transmission paint a clear picture: 19 MPG in the city and 25 MPG on the highway. That city figure reflects the stop-and-go driving that reduces fuel efficiency, even with the engine’s start/stop system. On the open road, the Cayman S settles into a respectable cruising speed, aided by its relatively lightweight construction and aerodynamic profile. The highway figure is achievable, but requires a disciplined right foot; explore the engine’s power reserves frequently, and that number will quickly drop.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2022 Porsche 718 Cayman S is $2,650. This calculation is based on driving 15,000 miles per year and using national average fuel prices. Of course, your actual fuel costs will vary depending on your driving habits, the type of fuel you use (premium is recommended), and fluctuations in gas prices. Aggressive driving, shorter trips, and consistent city driving will inflate that number substantially. This isn’t a budget car to run.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy for the 718 Cayman S can differ significantly. Drivers who frequently engage the Sport or Sport Plus modes, or who enjoy spirited acceleration, should expect to see numbers closer to the city rating, even on mixed driving cycles. Those who prioritize smooth acceleration and consistent highway speeds can likely match or even slightly exceed the EPA’s highway estimate. Ultimately, driver behavior plays a significant role in the achievable fuel economy of this performance-oriented car.

How it compares

Compared to other sports cars in its class, the 718 Cayman S lands somewhere in the middle. The BMW M240i, for example, manages a combined 26 MPG with its inline-six engine. A Nissan Z Performance clocks in at 22 MPG combined, despite packing significantly more horsepower. Even within the Porsche family, you can find vehicles with better fuel economy; browse all Porsche fuel economy data to see models like the Macan, which offers more practicality. Comparing to Porsche’s own Cayenne and other family vehicles is not the point, however. The Cayman buyer wants a compact, powerful sports car.

Tips to maximize efficiency

Resist the urge to bury the throttle at every opportunity. The 718 Cayman S is designed to be engaging, but gentle acceleration and smooth braking will significantly improve fuel economy. Its turbocharged engine delivers plenty of torque at lower RPMs, so there’s no need to constantly rev it to the redline.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Check your tire pressures regularly to ensure they are at the recommended levels. This also helps preserve handling.

Avoid unnecessary weight. Carrying extra cargo in the car adds weight, which increases fuel consumption. Remove any unnecessary items from the trunk and passenger compartment.

Consider the driving mode. While Sport and Sport Plus modes sharpen throttle response and firm up the suspension, they also reduce fuel efficiency. Use the Normal or Individual mode for everyday driving to maximize MPG.

Proper maintenance is critical to any car’s efficiency. Follow the recommended maintenance schedule in your owner’s manual, including regular oil changes, air filter replacements, and spark plug checks. A well-maintained engine runs more efficiently. You can research 718 MPG across all years if you’re curious about how older models compare.
