The 2016 Porsche Cayman S 3.4L 6-cyl gets 24 MPG combined, and its purpose isn’t maximizing fuel efficiency. It’s a precision instrument for cornering and delivering a visceral driving experience. Buyers prioritize a beautiful and expertly engineered sports car, not fuel efficiency.

City and highway performance

The EPA estimates for the 2016 Cayman S are 21 MPG in the city and 29 MPG on the highway. The city figure reflects urban driving’s stop-and-go nature, where the Cayman’s responsive throttle and surprisingly well-behaved automatic transmission (AM-S7) can still provide enjoyable bursts of acceleration. The highway MPG shows the car’s ability to cruise comfortably at higher speeds, though exploiting the engine’s mid-range power affects that number for many drivers. Remember these figures are obtained under controlled conditions, and your driving style impacts your MPG.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Porsche Cayman S at $2,400. This estimate assumes 15,000 miles driven per year and uses national average fuel prices. The actual amount you spend on fuel could be significantly higher or lower depending on mileage, location (fuel prices vary), and driving habits. The Cayman S also requires premium fuel, so the cost per gallon impacts your annual fuel expenditure further. This annual cost might be acceptable for weekend enjoyment and occasional spirited drives, but for daily commuters covering longer distances, it’s a factor to consider, potentially making them check out all all Porsche fuel economy data.

Real-world expectations

While the EPA estimates provide a baseline, real-world MPG in the 2016 Cayman S often varies. Drivers who frequently engage in spirited driving, track days, or spend time in heavy traffic are likely to see figures closer to the high teens or low twenties. Conversely, those who primarily drive on the highway and use a more moderate driving style might achieve or slightly exceed the EPA’s 29 MPG estimate. The Cayman S, with its naturally aspirated 3.4L flat-six engine, rewards smooth inputs and penalizes aggressive acceleration. Factors like ambient temperature, tire pressure, and even the grade of fuel influence observed fuel economy.

How it compares

The 2016 Cayman S lands in the middle of its class for fuel efficiency. A comparable BMW M235i from the same year, with its turbocharged inline-six, achieves around 22 MPG combined. The Nissan 370Z, known for its raw performance, fares worse, often struggling to reach 20 MPG in combined driving. A four-cylinder sports car like the Audi TT delivers significantly better fuel economy, closer to 26 MPG combined, but sacrifices some of the Cayman’s visceral driving experience. These are key considerations for the enthusiast seeking thrilling performance while balancing running costs. Browsing through the CAYMAN MPG across all years can offer futher insight.

Tips to maximize efficiency

Minimize aggressive acceleration, any hard launch or sudden burst of speed sucks fuel. Aim for smooth acceleration to keep the engine operating in its most efficient range. Anticipate traffic flow and avoid unnecessary braking.

Maintain proper tire pressure because underinflated tires increase rolling resistance, impacting fuel economy. Check your tires regularly and inflate them to the pressure recommended on the door jamb sticker. This improves MPG without sacrificing performance or handling.

Avoid idling, which wastes fuel. If you’re going to be stopped for more than a minute, turn off the engine. The Cayman’s engine starts quickly and reliably, so there’s no need to let it run unnecessarily, especially in stop-and-go traffic.

Use cruise control on the highway to maintain a steady speed, which can improve fuel economy on long drives. Avoid constant acceleration and deceleration. Be aware of the terrain and adjust your speed.

Keep up with scheduled maintenance for a more efficient engine. Follow the manufacturer’s recommended service schedule, including oil changes, air filter replacements, and spark plug maintenance. Proper maintenance ensures optimal engine performance and fuel economy.
