21 MPG combined. Let’s be honest, the owner of a 2016 Porsche 911 Targa 4S probably isn’t prioritizing fuel efficiency. It’s not a grocery-getter, it’s a statement. It’s exhilarating performance and iconic design, and the fuel economy is simply a compromise accepted by those who crave the unique Targa experience. These are buyers who prioritize the open-air feel and unmistakable silhouette over squeezing every last mile out of a gallon.

City and highway performance

The EPA estimates for the 2016 Porsche 911 Targa 4S, equipped with its 3.8L 6-cylinder engine and the automatic (AM-S7) transmission, reveal 18 MPG in the city and 25 MPG on the highway. The city figure reflects stop-and-go traffic, where the engine consumes more fuel during acceleration and idling. The highway number is more palatable, showing that at consistent speeds, the Targa 4S can deliver respectable, though not exceptional, efficiency. Remember this is a performance vehicle. When pushed, expect these numbers to drop. Gentle cruising will help you approach, or even slightly exceed, the EPA estimate.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2016 Porsche 911 Targa 4S is $2,750. This figure is based on driving 15,000 miles per year and assumes the use of fuel at prevailing national average fuel prices. Individual fuel costs will fluctuate depending on driving habits, location, and fuel prices in your area. However, the $2,750 provides a useful benchmark for comparing the cost of fueling this Porsche to other vehicles. Owners should factor this into their budget, alongside maintenance, insurance, and other expenses associated with owning a high-performance sports car.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy often varies. Aggressive acceleration, frequent short trips, and neglecting routine maintenance can all negatively impact fuel efficiency. Driving with a light foot, adhering to a consistent speed on the highway, and keeping your 911 properly maintained can help you achieve figures closer to, or even slightly better than, the official EPA estimates. Don’t expect Prius-like numbers, but understand that your driving behaviour directly influences your fuel consumption. Many owners will see even lower figures in city driving.

How it compares

Compared to other sports cars in its class, the 2016 Porsche 911 Targa 4S sits somewhere in the middle of the fuel economy spectrum. For instance, the Audi R8 V10, with its more powerful engine, typically achieves around 16 MPG combined, making the Targa 4S seem relatively fuel-efficient. On the other hand, a Jaguar F-Type R Coupe can achieve around 19 MPG combined, even with the supercharged V8. Even within the 911 family, you’ll find variations. The base 911 Carrera might achieve slightly better numbers due to its smaller engine and lighter weight. For those exploring the range, it is worth comparing 911 MPG across all years. The decision ultimately comes down to balancing performance needs with fuel economy considerations. Drivers can also compare all Porsche fuel economy data to see how the 911 models stack up against each other.

Tips to maximize efficiency

Pay close attention to tire pressures. The 911’s handling is sensitive to tire inflation, and underinflated tires create more rolling resistance, increasing fuel consumption. Check your tire pressures regularly and maintain them at the recommended levels listed on the driver’s side door jamb.

Use the automatic transmission’s programming to your advantage. Avoid aggressive acceleration and let the transmission shift smoothly through the gears. The Targa 4S is equipped with an excellent transmission, and it doesn’t need to be forced to hold gears unnecessarily.

Minimize idling time. Idling consumes fuel without covering any distance. If you anticipate being stopped for more than a minute, it’s best to turn off the engine.

Lighten your load. Excess weight compromises fuel economy in any vehicle. Remove unnecessary items from the Targa 4S to reduce the amount of energy required to accelerate and maintain speed. This isn’t usually a problem in a two-seater, but remove heavy items lingering in the trunk.

Consider the drive mode. If you are not trying to break any lap records, drive in the normal or efficiency modes to reduce fuel consumption with the relaxed setting programmed into the vehicle. The more aggressive settings will increase fuel usage and are not always needed.
