23 MPG combined isn’t going to impress any Prius owners, but it’s almost beside the point for the 2022 Porsche 718 Cayman T. This isn’t a commuter car; it’s a precision instrument designed for driving pleasure. While efficiency is appreciated, it’s not the primary motivator for buyers drawn to its mid-engine balance, razor-sharp handling, and the Porsche badge on the hood. They prioritize the visceral connection to the road above all else, and they’re willing to pay a premium, both at the dealership and at the pump, for that experience. This car caters to those who relish spirited weekend drives and track days, not maximizing fuel savings on the daily grind.

City and highway performance

The EPA estimates the 718 Cayman T will achieve 21 MPG in the city and 27 MPG on the highway. The city number reflects the stop-and-go nature of urban driving, where the engine’s responsiveness gets a workout, but so does its fuel consumption. The highway figure is more palatable, as the Cayman’s aerodynamic shape and well-calibrated seven-speed automatic transmission (AM-S7) allow it to cruise relatively effortlessly at steady speeds. However, understand that dipping into the Cayman’s performance reserves, unleashing its acceleration for overtaking or simply enjoying the open road, will inevitably impact that highway MPG number. A light foot yields better economy, but requires considerable restraint in a car this eager.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,500 for the 2022 Porsche 718 Cayman T. This calculation is based on driving 15,000 miles per year, using national average fuel prices. Remember that fuel prices fluctuate regionally and over time, so this figure is merely a guide. And the actual cost can vary significantly based on individual driving habits. A more aggressive driver, frequently exploiting the car’s performance capabilities, can easily exceed this estimate, while a more conservative driver may see slightly lower annual expenses. $2,500 is the benchmark for budgeting, acknowledging that real-world expenditures are likely to deviate.

Real-world expectations

The official EPA figures provide a useful starting point but rarely tell the whole story. 718 Cayman T owners often report fuel economy figures that vary from the EPA estimates, heavily dependent on driving style and the types of roads driven. Those prioritizing backroads and track days will undoubtedly see lower MPG than someone using it primarily for highway cruising. The temptation to exploit the Cayman’s performance is strong, meaning even drivers who intend to be fuel-conscious might find themselves succumbing to the allure of its acceleration and handling. Consider the EPA numbers a best-case scenario, and factor in your personal driving habits when estimating your real-world fuel costs. Reviewing 718 MPG across all years can give you some additional insights into owner experiences across different model years.

How it compares

Compared to other sports cars, the 718 Cayman T occupies a specific niche. The BMW M240i, for example, offers a more potent inline-six engine but delivers a slightly lower 22 MPG combined. The Nissan Z, with its turbocharged V6, also lands around 22 MPG. The Alpine A110, a direct competitor in terms of driving experience, is not sold in the US market. Within Porsche’s own lineup, you’ll find the larger 911 Carrera to have a slightly lower average fuel economy. The fuel economy of the Cayman T may be reasonable, but those cross-shopping against high-performance hot hatchbacks like the Honda Civic Type R (28 MPG combined) or the VW Golf R (23 MPG) need to recognize that they will benefit from the more practical hatchback configuration with similar fuel usage.

Tips to maximize efficiency

Despite its sporting intentions, the 718 Cayman T can achieve respectable fuel economy with mindful driving. Avoiding aggressive acceleration and maintaining a steady pace, both in the city and on the highway, can significantly improve MPG. Use the car’s cruise control system wherever possible on the open road, especially on flat stretches, to maintain a consistent speed and minimize unnecessary throttle adjustments.

Pay attention to the tire pressure. Optimal tire pressure, as indicated on the door jamb sticker, reduces rolling resistance and improves fuel efficiency. Regularly checking and maintaining proper tire inflation is a simple but effective way to save fuel.

Consider the driving mode. Selecting the “Normal” driving mode will temper the throttle response and shift patterns to prioritize efficiency over performance. While it might slightly tame the Cayman’s sporty character, it can noticeably improve fuel economy, particularly in urban driving.

Reduce weight. The 718 Cayman T is relatively lightweight, unnecessary cargo adds to the vehicle’s overall weight and reduces fuel efficiency. Remove any items from the trunk or passenger compartment that are not essential for your journey.

Proper maintenance is key. A well-maintained engine runs more efficiently. Following the manufacturer’s recommended maintenance schedule, including regular oil changes and air filter replacements, ensures the engine is operating optimally and helps maximize fuel economy, while learning more about all Porsche fuel economy data.
