The 2016 Porsche 911 Carrera Cabriolet 3.4L 6-cyl gets 23 MPG combined. This won’t win any hypermiling awards, but that’s also not the purpose of this car. This is a machine engineered for pure driving pleasure; its fuel consumption is a concession to practicality, a figure that allows its wealthy owners to enjoy their sports car without constant fuel stops.

City and highway performance

The EPA estimates that this 911 achieves 21 MPG in the city and 28 MPG on the highway. This split reflects the character of the car. In urban environments, the 3.4L flat-six engine, while tractable, operates with more frequent acceleration and deceleration. The automatic transmission, labeled AM-S7, hunts for the optimal gear, but stop-and-go traffic inevitably takes its toll.

Out on the open road, the 911 Carrera Cabriolet can stretch its legs. The engine settles into a more efficient cruising rhythm, making the most of its inherently balanced design. 28 MPG is achievable when driven with restraint, a figure that allows for relatively long-distance touring with the top down.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,500 for the 2016 Porsche 911 Carrera Cabriolet. This calculation assumes 15,000 miles of driving per year, using a national average fuel price. Note that premium fuel is required, and fluctuations in fuel prices will directly impact this figure. For someone who drives more aggressively, or lives in an area with higher fuel costs, the real-world annual expenditure could be considerably higher.

Real-world expectations

Enthusiast cars like the 911 are rarely driven with fuel economy in mind. Owners prize the visceral acceleration, the spine-tingling exhaust note, and the sheer joy of carving up a winding road. Expect a more realistic MPG figure closer to 20 MPG in mixed driving if you regularly indulge in the performance this car offers.

How it compares

Compared to its rivals, the 2016 Porsche 911 Carrera Cabriolet’s fuel economy is within the expected range for a high-performance sports car. A Jaguar F-Type Convertible with the base engine returns around 22 MPG combined. The Chevrolet Corvette Stingray Convertible sees around 19 MPG in the city. These differences, though seemingly small, can add up over time. However, for the 911 buyer performance, exclusivity, and the unique Porsche driving experience typically outweigh marginal fuel cost concerns.

Tips to maximize efficiency

Smooth and gradual acceleration is best. Avoid sudden bursts of speed or heavy braking, as these actions significantly impact fuel consumption. Let the automatic transmission do its job, and avoid using the paddle shifters unless necessary. A relaxed driving style can yield surprisingly good results.

Ensure that your tires are inflated to the recommended pressure. Underinflated tires increase rolling resistance, which in turn reduces fuel economy. Check your tire pressure regularly, especially if you live in an area with fluctuating temperatures.

Reduce unnecessary weight in the car. Carrying extra cargo adds to the vehicle’s load, requiring the engine to work harder. Remove any items that you don’t need, especially heavy objects in the trunk.

Proper maintenance is critical for optimal fuel efficiency. Regular oil changes, air filter replacements, and spark plug maintenance ensure that the engine is running at its peak performance. Follow the manufacturer’s recommended service intervals.

Minimize idling. If you’re stopped for more than a minute, turn off the engine. Modern engines are designed to handle frequent restarts without causing excessive wear. Excessive idling consumes fuel and reduces your overall MPG.
