19 MPG combined. That’s the number for the 2022 Porsche 911 Carrera 4 GTS with the 3.0L flat-six and automatic transmission. Don’t dismiss it as bad, because this isn’t a grocery-getter. It’s a precision instrument, designed to deliver driving engagement and performance. Fuel economy is a distant consideration for the buyer; they’re prioritizing the GTS badge, the engine note, and the car’s connection to the road. They’re willing to pay at the dealership and at the pump for that experience.

City and highway performance

The EPA estimates for the 2022 911 Carrera 4 GTS break down to 17 MPG in the city and 23 MPG on the highway. The city figure reflects urban driving, where the engine idles and accelerates frequently. The highway number demonstrates a modest improvement. The 8-speed PDK transmission helps by keeping the engine efficient when cruising. Even on the open road, resisting the urge to use that 473 horsepower and 420 lb-ft of torque will be a challenge for most drivers.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Porsche 911 Carrera 4 GTS at $3,050. Based on driving 15,000 miles per year, with a mix of city and highway driving, and using the national average fuel price at the time of calculation. Fuel prices fluctuate, and your actual fuel cost may vary depending on your driving habits and location, however, $3,050 is still only a small dent in the overall cost of ownership for this vehicle.

Real-world expectations

Real-world MPG can vary. Factors like driving style, traffic, and tire pressure can all impact fuel economy. Drivers who frequently engage launch control, spend time on the track, or enjoy spirited driving will likely see numbers lower than the EPA estimates. Those who prioritize smooth acceleration and maintain consistent speeds on the highway may achieve slightly better fuel economy. See all Porsche fuel economy data for more perspective.

How it compares

Context is important. While 19 MPG might seem poor compared to a hybrid or some performance SUVs, it aligns with the competition. The BMW M4 Competition xDrive, another high-performance coupe with all-wheel drive, achieves a similar 18 MPG combined. The Jaguar F-Type R Coupe, with its supercharged V8, fares worse at 18 MPG combined. Even Porsche’s own 718 Cayman GTS 4.0, while lighter and smaller, manages only 20 MPG combined. Performance comes at a cost, and buyers are generally willing to accept the trade-off.

Tips to maximize efficiency

Even behind the wheel of a 911 GTS, drivers can try to get better fuel efficiency. Avoid aggressive acceleration and hard braking. The PDK transmission is programmed to shift efficiently, so let it do its job and resist downshifting for maximum power.

Check and maintain proper tire pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Consult the sticker on the driver’s side doorjamb for the recommended tire pressure for your 911.

Minimize idling. If you’re stopped for more than a brief moment, turn off the engine. Modern cars are designed to restart quickly, and idling consumes fuel.

Consider using the “Normal” driving mode instead of “Sport” or “Sport Plus” for everyday driving. While those modes enhance throttle response and shift points, they also decrease fuel efficiency. The “Normal” mode still provides ample performance for most situations, while helping to conserve fuel. Study the 911 MPG across all years to better understand how model variations affect the numbers.
