19 MPG combined is the reality for anyone considering the 2022 Porsche 911 Carrera GTS with its 3.0L turbocharged flat-six and 8-speed PDK automatic. This isn’t a Prius. This car exists to deliver a visceral driving experience, a connection to the road, and speed. Fuel economy takes a back seat, though owners still consider it.

City and highway performance

The 911 Carrera GTS, even in the automatic version, reflects a compromise driven by performance. City driving nets you around 17 MPG. Stop-and-go traffic, aggressive acceleration, and the general nature of cities contribute to this figure. On the open highway, you can expect to see around 23 MPG. This relies on consistent speeds and a lighter foot. Avoid tapping into the engine’s power too much, as the temptation will hurt your highway mileage.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,050 for the 2022 Porsche 911 Carrera GTS. This figure is calculated based on driving 15,000 miles per year, using a blend of city and highway driving, and factoring in national average fuel prices. It is a useful benchmark, but it is an average. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and where you live. If you track the car regularly or live in a city with particularly high gas prices, expect to pay considerably more.

Real-world expectations

The official numbers are there, but the real-world mileage of the 911 GTS depends on the driver. Someone who enjoys spirited weekend drives and occasional track days will likely see MPG figures below the EPA estimates. A driver who primarily uses the car for longer highway commutes and tries to be gentle with the throttle might achieve slightly better fuel economy. It’s a 911 , restraint is usually the first thing to disregard when you slide into the driver seat.

How it compares

Consider the competition. The Chevrolet Corvette Stingray, a similarly performance-focused sports car, achieves around 19 MPG combined with its standard V8. The BMW M4 Competition manages about 18 MPG combined. Even within the Porsche family, comparing 911 MPG across all years shows the GTS consistently sacrifices fuel efficiency for increased power and performance. A standard 911 Carrera might provide a slight improvement in MPG, but it also means losing out on the GTS’s sharper handling and more potent engine. If fuel economy is a concern, you might consider looking at all Porsche fuel economy data to see if the Porsche Taycan is more your speed.

Tips to maximize efficiency

Fuel economy isn’t the primary reason someone buys a 911 GTS, but there are ways to make the most of each gallon. Use the “Normal” driving mode when possible. This mode softens throttle response and encourages the transmission to upshift earlier, reducing fuel consumption during everyday driving. Avoid using Sport or Sport+ modes, as these settings prioritize performance over efficiency.

Driving smoothly is important. Avoid hard acceleration and abrupt braking. Anticipate traffic flow and maintain a consistent speed whenever possible. Every press of the accelerator tells the engine to feed more fuel, and heavy braking wastes the energy you just spent burning that fuel.

Tire pressure plays a role. Ensure your tires are inflated to the recommended pressure, often found on a sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, which hurts fuel economy. Check your tire pressure regularly, especially during temperature changes.

Finally, consider lighter wheels. The GTS uses lightweight wheels, but there are even lighter aftermarket options available. Reducing the weight of the car requires less energy to accelerate and maintain speed, resulting in small increases in fuel efficiency.
