25 MPG combined isn’t the main reason people buy the 2016 Porsche Cayman GTS. People purchase this car because it’s precise, designed to deliver driving thrills, not maximize fuel savings. The Cayman GTS demands, and rewards, an involved driver, an experience that involves balancing performance and efficiency.

City and highway performance

The official EPA estimates list the Cayman GTS at 21 MPG in the city and 30 MPG on the highway. The city number reflects urban driving’s stop-and-go conditions, where the 3.4L flat-six engine is constantly accelerating and decelerating. The highway figure, while impressive for a performance car, becomes achievable when cruising at a steady speed. But these numbers depend on restraint, if you frequently accelerate, those highway figures will decrease as you enjoy the engine’s sounds and acceleration.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2016 Porsche Cayman GTS is $2,300. This figure assumes 15,000 miles per year and average national fuel prices. Fuel costs will vary depending on driving habits, local fuel prices, and the gasoline used. The Cayman GTS requires premium fuel, which costs more, further influencing running costs.

Real-world expectations

The EPA numbers are a useful benchmark, but real-world fuel economy for the 2016 Cayman GTS will likely vary depending on the driver. Drivers who often use the engine’s performance will see lower numbers, maybe below 20 MPG combined. However, drivers who drive more calmly, especially on longer trips, may achieve or exceed the official highway estimate. The Cayman GTS is a performance car, and its fuel economy depends on how it’s driven.

How it compares

Compared to other sports cars, the 2016 Cayman GTS is in the middle regarding fuel economy. A BMW M2, for example, gets about 22 MPG combined with its turbocharged inline-six engine, a little less than the Cayman. A Chevrolet Corvette Stingray, with more power, achieves around 19 MPG city and 29 highway. A comparable Audi TTS offers similar performance to the Cayman with fuel economy ratings of 23 city, 31 highway, and 27 combined. The buyer choosing between these vehicles isn’t prioritizing fuel economy, but if running costs matter, these details can influence a decision.

Tips to maximize efficiency

Even though efficiency isn’t a priority, small changes can improve fuel economy. The PDK transmission has fuel-saving features, so keep it in automatic mode during normal driving. Rapid acceleration and hard braking reduce fuel efficiency. Predict traffic and keep a consistent speed when possible.

Regular maintenance helps fuel economy. Make sure the engine is tuned and the tires are properly inflated. These small things can affect fuel consumption.

Use Sport or Sport Plus driving modes sparingly. While these modes improve throttle response and shift points for performance, they increase fuel consumption. Only use them when you want the car’s potential and use Normal mode for everyday driving.

Remove extra weight from the car. Extra weight requires more energy to accelerate and maintain speed. Remove unneeded items from the trunk and passenger area to reduce weight and improve fuel economy. See more information on CAYMAN MPG across all years.
