22 MPG combined isn’t the main reason to buy a 2016 Porsche 911 Carrera 4 Cabriolet. A six-figure performance car isn’t expected to have Prius-like efficiency. It’s a car for thrills, open-air driving, and Porsche’s precise handling. The 22 MPG is a footnote, a trade-off for driving enjoyment. Buyers prioritize performance and can afford to fuel it.

City and highway performance

The EPA estimates 20 MPG in the city and 27 MPG on the highway. The city figure reflects stop-and-go traffic, where the 3.4L flat-six uses more fuel. The 27 MPG highway rating shows the C4 Cabriolet can be efficient at steady speeds. The seven-speed automatic transmission (AM-S7) helps, choosing gears for fuel economy but providing fast shifts for performance. Drivers on the open road can see figures near 27 MPG, while city drivers should expect around 20 MPG.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Porsche 911 Carrera 4 Cabriolet at $2,650. This assumes 15,000 miles per year and national average fuel prices. Premium fuel is required, increasing the annual cost. Individual spending varies, but $2,650 is a reasonable estimate. It’s a cost of owning a high-performance car, a cost the target demographic can afford.

Real-world expectations

EPA estimates are guidelines, but real-world fuel economy for the 2016 911 C4 Cabriolet changes based on driving style. Aggressive acceleration and Sport mode will decrease fuel efficiency. Moderate driving and cruise control on the highway can yield results close to the EPA’s 27 MPG highway figure. Owners tracking fuel consumption may see changes based on seasons and fuel blends.

How it compares

The 2016 911 Carrera 4 Cabriolet’s fuel economy is competitive compared to other high-performance convertibles. A BMW M4 Convertible achieves around 19 MPG combined with its twin-turbocharged inline-six. The Jaguar F-Type Convertible, depending on the engine, ranges from the high teens to low twenties in combined MPG. You can browse 911 MPG across all years. The Carrera 4 Cabriolet offers performance and efficiency compared to alternatives, making it an option for drivers who want performance and some gas savings. You can also view all Porsche fuel economy data to see how it compares across the brand.

Tips to maximize efficiency

Avoid aggressive acceleration. The 911’s flat-six engine is responsive, but sudden speed decreases fuel consumption. Gradual acceleration allows more efficient operation.

Use cruise control on the highway. Consistent speed minimizes acceleration and deceleration, improving fuel economy during long drives. Cruise control helps cover distances and get closer to the stated highway MPG.

Monitor tire pressure regularly. Underinflated tires increase rolling resistance, which reduces fuel efficiency. Proper inflation enhances fuel economy and handling.

Reduce idling time. Idling wastes fuel. If you anticipate a long stop, turn off the engine to conserve fuel. A high-performance engine burns fuel when idling.
