22 MPG combined isn’t going to win any fuel economy awards, but it’s also not the main concern if you’re considering a 2016 Porsche 911 Targa 4 with the 3.4L flat-six. This isn’t a car bought for purely rational reasons; it’s a statement, an indulgence, and a uniquely visceral driving experience wrapped in a retro-cool package. Those who prioritize less gas will look elsewhere. This car is for those who value the thrill of a naturally aspirated engine and the open-air experience offered by the Targa top, even if it means a bit more time at the pump.

City and highway performance

The EPA estimates for the 2016 911 Targa 4 peg city driving at 19 MPG and highway driving at 26 MPG. These figures reflect the realities of driving a sports car powered by a rev-happy engine.

In the city, stop-and-go traffic inevitably drags down fuel consumption. The temptation to accelerate quickly between lights, enjoying the immediate throttle response and characteristic flat-six snarl, further diminishes efficiency. Out on the open road, maintaining a steady cruising speed yields the promised 26 MPG, but even there, the urge to dip into the engine’s powerband will impact the numbers.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Porsche 911 Targa 4 at $2,650. This figure is based on driving 15,000 miles per year, with an estimated fuel price derived from national averages. It’s important to remember that this is just an estimate.

Your actual fuel cost will vary depending on your driving habits, the type of roads you typically drive on, and, of course, the price of gasoline in your area. A lead foot and premium fuel prices will quickly push that $2,650 figure upwards.

Real-world expectations

While the EPA estimates provide a benchmark, real-world fuel economy often differs. Owners report mileage that aligns reasonably well with the EPA numbers. Those who prioritize fuel efficiency and employ a conservative driving style might even see slightly better results, especially on the highway. However, those who regularly exploit the 911’s performance capabilities should expect to see fuel economy figures closer to the city estimate, or even lower. Aggressive acceleration, frequent gear changes, and high-speed cruising take their toll.

How it compares

Compared to other sports cars in its class, the 2016 911 Targa 4’s fuel economy is fairly typical. A comparable Jaguar F-Type R Coupe (automatic) with its supercharged V8 will see closer to 16 MPG combined, highlighting the relative efficiency of the Porsche’s flat-six. A BMW M4 convertible gets an estimated 20 MPG combined, a bit lower than the Targa. Even a more pedestrian Chevrolet Corvette Stingray convertible can achieve around 19 MPG in the city, demonstrating that performance and fuel economy are often at odds. Buyers cross-shopping these vehicles need to weigh the importance of performance, features and badge cachet against the cost of fueling their choices. For a broader picture, it’s useful to consult 911 MPG across all years to see how the Targa 4 compares to other 911 variants.

Tips to maximize efficiency

While this car encourages spirited driving, there are still ways to improve fuel economy. Avoid unnecessary idling. Modern engines are designed to be efficient when running, even at a standstill. Extended idling wastes fuel and contributes to emissions, so shut off the engine if you’re stopped for more than a minute or two.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressures regularly, and inflate to the recommended levels found on the driver’s side doorjamb. This is a simple step that can make a noticeable difference.

Use cruise control on long highway journeys. Maintaining a constant speed minimizes fluctuations in fuel consumption. The Porsche’s automatic transmission will also select the most efficient gear for the conditions, further optimizing fuel economy. Just be mindful of traffic and remain alert.

Anticipate traffic flow and drive smoothly. Avoid sudden acceleration and braking, as these actions waste fuel. By anticipating traffic conditions and maintaining a consistent pace, you can minimize unnecessary fuel consumption. Thinking ahead can save some premium gasoline.

Consider the driving mode. While the 911 offers different driving modes, the “Normal” mode prioritizes fuel efficiency by optimizing throttle response and shift points. While it might not be the most exhilarating setting, it can help to improve fuel economy, especially in stop-and-go traffic.
