21 MPG combined is, let’s be honest, not the main reason someone buys a 2016 Porsche 911 Carrera 4 GTS. This car is about visceral thrills, all-weather confidence, and the unique experience that only a high-revving, naturally aspirated flat-six engine can deliver. This is a car for enthusiasts who prioritize performance above all else, but also demand everyday usability and a certain level of practicality. They understand that smiles per gallon are often more important than miles per gallon, and they’re willing to accept the fuel economy trade-off for the sheer joy this machine provides.

City and highway performance

The 911 Carrera 4 GTS achieves an EPA-estimated 19 MPG in the city and 25 MPG on the highway. The city figure reflects the realities of stop-and-go traffic, where the 3.8L engine is less efficient. The highway number highlights the car’s ability to cruise comfortably at higher speeds, where it benefits from its aerodynamic design and the seven-speed PDK automatic transmission (AM-S7) which keeps the revs relatively low.

Drivers who spend a significant amount of time in urban environments will naturally see a lower average fuel economy than those who primarily use the car for longer trips or open road driving. The all-wheel-drive system, while enhancing grip and stability in all conditions, also adds some weight and mechanical drag, impacting fuel economy slightly compared to rear-wheel-drive 911 models.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2016 Porsche 911 Carrera 4 GTS at $2,750. This figure is based on driving 15,000 miles per year and using then-current national average fuel prices. Keep in mind that this number will fluctuate depending on your individual driving habits, the type of fuel you use, and the prevailing fuel prices in your area. Aggressive driving, frequent short trips, and a preference for premium fuel (which is highly recommended for optimal performance) will all contribute to a higher annual fuel expenditure.

Real-world expectations

While the EPA estimates provide a useful benchmark, real-world fuel economy for the 2016 911 Carrera 4 GTS will vary considerably depending on driving style and conditions. Drivers who frequently exploit the car’s performance potential can expect to see fuel economy figures closer to the low end of the EPA range, or even below. Conversely, those who adopt a more mellow driving style and prioritize efficient driving techniques may be able to achieve figures closer to, or even slightly above, the EPA estimates. It’s not unreasonable to expect anywhere between 17 MPG and 27 MPG depending on usage. The 911 MPG across all years can be found on this site.

How it compares

Compared to other sports cars in its class, the 2016 Porsche 911 Carrera 4 GTS’s fuel economy is neither exceptional nor particularly poor. A comparable Mercedes-AMG GT, for example, delivers around 16 MPG city and 22 MPG highway, highlighting the Porsche’s relative efficiency. The Jaguar F-Type R, another popular choice, manages roughly 15 MPG city and 24 MPG highway with its supercharged V8 engine, placing it slightly behind the 911 in terms of overall fuel efficiency. A BMW M4 offers approximately 17 MPG city and 26 MPG highway, a marginal improvement. These comparisons demonstrate that while performance is the primary focus for these vehicles, fuel economy is a factor that buyers should consider when weighing their options. The slightly better efficiency of the Porsche 911 Carrera 4 GTS could be a deciding factor for buyers concerned about fuel costs and less gas.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The 3.8L flat-six loves to rev, but using the full range of its capabilities will significantly reduce fuel economy. Smooth, progressive inputs on the throttle and brake pedal will help you conserve fuel without sacrificing too much performance. Let the PDK do its job; it’s programmed for optimal efficiency.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, leading to lower fuel economy. Check your tire pressures regularly and ensure they are inflated to the recommended levels, which can be found on the driver’s side doorjamb or in the owner’s manual. This is especially important for high-performance sports cars like the 911.

Reduce unnecessary weight. Carrying extra items in the car adds weight, which in turn reduces fuel economy. Remove any unnecessary items from the trunk and passenger compartment to minimize the load on the engine.

Plan your routes carefully. Avoid congested areas and routes with frequent stop-and-go traffic whenever possible. Choose routes with smoother traffic flow and more consistent speeds to optimize fuel economy. Use navigation apps to find the most efficient routes.

Consider using the Sport or Sport Plus modes sparingly. While these modes enhance performance and driving enjoyment, they also increase fuel consumption. Use them only when you really need the extra performance, and switch back to a more efficient mode for everyday driving. The default driving mode is often the best choice for maximizing fuel economy.
