24 MPG combined isn’t going to win any fuel efficiency awards, but it’s a respectable figure for the 2019 Porsche 911 Targa 4. Let’s be honest, nobody buys a Targa to beat a Prius. Buyers choose the Targa 4 for its iconic styling, open-air thrills, and the sure-footed grip of all-wheel drive in a package that offers everyday usability. If gas mileage was the main concern, they’d be looking elsewhere.

City and highway performance

The EPA estimates 22 MPG in the city and 28 MPG on the highway for the 2019 Porsche 911 Targa 4. The city figure reflects stop-and-go driving, where the engine is frequently idling or accelerating which decreases efficiency. The highway figure, obtained under more consistent speed conditions, is better. The seven-speed dual-clutch automatic transmission (PDK) helps optimize gas mileage in both scenarios, shifting smoothly and quickly to keep the engine in its most efficient rev range. This powertrain is efficient when you consider the power it delivers.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Porsche 911 Targa 4 will be about $2,400. This is based on driving 15,000 miles per year and using the national average fuel price for premium fuel. The 911 Targa 4 requires premium gasoline to deliver its advertised performance and efficiency. Individual fuel costs will vary depending on driving habits, local fuel prices, and the number of miles driven each year. However, $2,400 provides a benchmark for potential owners when budgeting for running costs.

Real-world expectations

While the EPA figures provide a baseline, real-world fuel economy can vary. Drivers with a heavy foot or those who drive spiritedly will likely see numbers below the EPA estimates. Conversely, drivers who prioritize fuel efficiency and spend most of their time on the highway may achieve slightly better results. Factors like tire pressure, vehicle maintenance, and even the weather can also play a role.

It’s reasonable to expect a range of 20-26 MPG in mixed driving conditions, but drivers should consider their own driving patterns when estimating fuel costs.

How it compares

The 2019 Porsche 911 Targa 4’s fuel economy is respectable compared to other performance vehicles, but not groundbreaking. A BMW M4 Convertible, for example, achieves a similar 24 MPG combined, despite being rear-wheel drive. The all-wheel drive system in the Targa 4 adds weight and complexity, impacting fuel efficiency.

A Jaguar F-TYPE R Convertible, with its supercharged V8, only manages 18 MPG combined. Within the Porsche family, checking 911 MPG across all years shows that other 911 variants, such as the base Carrera coupe, can achieve slightly better gas mileage due to lower weight and a simpler drivetrain.

For potential buyers, this gas mileage trade-off is often negligible compared to the Targa model’s appeal. If you are interested in other models from this brand, check all Porsche fuel economy data.

Tips to maximize efficiency

Maintaining proper tire pressure is an easy way to improve gas mileage. Check your tires regularly and inflate them to the recommended pressure listed on the driver’s side door jamb. Underinflated tires create more rolling resistance, increasing fuel consumption. Using the car’s “Normal” driving mode will prioritize gas mileage through less aggressive throttle mapping and earlier shifts.

Avoid aggressive acceleration and braking. Gradual acceleration allows the engine to operate more efficiently, and smooth braking recovers kinetic energy during deceleration. Anticipating traffic flow and avoiding sudden stops can also improve gas mileage.

Reduce unnecessary weight. Removing unnecessary items from the vehicle, such as golf clubs or extra luggage, can improve fuel efficiency. The lighter the car, the less energy it takes to move it. This might seem trivial, but every little bit helps.

Schedule regular maintenance. A well-maintained engine operates more efficiently. Keep up with scheduled maintenance, including oil changes, air filter replacements, and spark plug replacements. A properly tuned engine will deliver optimal gas mileage.

Consider the Targa 4’s purpose. It is a car that is meant to be enjoyed on the weekend, so don’t rely on it as your dedicated commuter car if you want improved mileage.
