20 MPG combined won’t win any fuel efficiency contests, but for an all-wheel drive, open-top sports car with nearly 400 horsepower, the 2023 Porsche 911 Targa 4 has different priorities. No Targa 4 buyer is considering a Prius. This car is about pushing limits while enjoying open-air thrills, and its fuel consumption shows that.

City and highway performance

The EPA estimates the 2023 Porsche 911 Targa 4 gets 18 MPG in the city and 24 MPG on the highway. These figures, from controlled testing, give a baseline for comparison. The 3.0-liter, twin-turbocharged flat-six engine, with Porsche’s eight-speed PDK transmission (AM-S8 in EPA parlance), delivers quick response and strong acceleration. The Targa’s all-wheel-drive system adds weight and complexity, slightly affecting mileage compared to rear-wheel-drive versions. The benefit is better grip and stability in all conditions, a major selling point.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2023 Porsche 911 Targa 4 at $2,900. This is based on driving 15,000 miles per year, with mixed city and highway driving, using the national average premium gasoline price. Your fuel costs will vary depending on your driving, location, and gas prices. This provides a benchmark for comparison. The $2,900 may seem high compared to more fuel-efficient cars, but consider the context. A Targa 4 buyer knows that performance costs money, and fuel consumption is part of owning a car like this, one that emphasizes excitement, exclusivity, and Porsche’s engineering.

Real-world expectations

While the EPA estimates are helpful, real-world fuel economy can be different. Aggressive driving, short trips, and idling will decrease fuel efficiency. Smooth acceleration, consistent speeds, and smart route planning can improve those numbers, possibly exceeding the EPA estimates. But remember this car is made for driving pleasure. Focusing only on gas mileage might take away from the experience that makes the Targa 4 so appealing.

How it compares

The 911 Targa 4’s fuel economy is similar to other high-performance convertibles and coupes. For example, the BMW M4 Competition Convertible, with its similar engine and all-wheel drive, gets an EPA combined rating of around 18 MPG. A Jaguar F-Type R Convertible is similar, with an EPA combined rating of about 19 MPG. Other Porsche 911s also offer similar numbers. Review 911 MPG across all years to see various models and their ratings. The Audi R8 Spyder, with its V10 engine, gets a combined 16 MPG. The Targa 4’s 20 MPG is typical for this type of sports car.

Tips to maximize efficiency

While saving every last mile may not be the main goal, you can improve the Targa 4’s fuel economy without losing driving fun. Use the car’s driving modes. “Normal” mode softens the throttle and shifts earlier, helping fuel economy in everyday driving. “Sport” mode is for maximum response, so plan accordingly.

Check tire pressures regularly. Properly inflated tires reduce rolling resistance, improving fuel efficiency and handling. See the sticker on the driver’s side doorjamb for the correct tire pressure. Tire pressure drops with temperature, so adjust as needed.

Avoid idling. Modern engines are efficient, and idling wastes fuel. If you’ll be stopped for more than a minute or two, turn off the engine, especially in city driving.

Anticipate traffic and drive smoothly. Smooth acceleration and braking reduce fuel use compared to aggressive driving. Keep a safe following distance and watch traffic to avoid unnecessary acceleration and deceleration.

Follow the maintenance schedule. A well-maintained engine is more efficient. Follow Porsche’s recommended schedule for oil changes, air filter replacements, and other services. A clean engine runs efficiently.
