19 MPG combined isn’t going to win any fuel-sipping contests, but it’s not terribly surprising for a Porsche 911 Targa 4 GTS. This isn’t a car bought for its frugality. It’s bought for its intoxicating blend of performance, open-air driving, and iconic design. Fuel economy is a distant consideration for the enthusiast who prioritizes the visceral thrill of a turbocharged flat-six engine and the unique experience of a Targa top.

City and highway performance

The EPA estimates put the 911 Targa 4 GTS at 17 MPG in the city and 22 MPG on the highway. The city figure reflects the realities of stop-and-go traffic, where the engine spends more time idling and accelerating. The highway number is more palatable, suggesting that longer cruises can yield relatively reasonable fuel consumption, especially if driven conservatively (a challenging feat, admittedly, in a car this engaging).

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 Porsche 911 Targa 4 GTS at $3,050. This figure is based on driving 15,000 miles per year and using national average fuel prices. Given that premium fuel is required, and many owners likely drive fewer than 15,000 miles annually, this number provides a baseline understanding of ownership expenses. The actual cost will vary depending on driving habits and local fuel prices. However, the $3,050 figure offers a standardized way to compare it to other vehicles.

Real-world expectations

While the EPA figures offer a benchmark, real-world fuel economy often differs, and this holds especially true for a performance car like the 911 Targa 4 GTS. Aggressive driving, frequent short trips, and extended idling will all negatively impact fuel consumption. Drivers who regularly exploit the car’s performance capabilities engaging launch control, pushing the engine to its redline, and enjoying spirited backroad drives should expect to see numbers below the EPA estimates. Conversely, those who prioritize smooth acceleration and consistent speeds on the highway may achieve figures closer to the 22 MPG highway rating. It’s a trade-off, and one that buyers of this particular model are generally willing to accept.

How it compares

Compared to other high-performance sports cars, the 911 Targa 4 GTS’s fuel economy is within the expected range. The BMW M4 Competition xDrive convertible, for example, manages 16 MPG city and 23 MPG highway, putting it in roughly the same ballpark. The Jaguar F-Type R convertible, a more overtly performance-focused machine, reports 15 MPG city and 24 MPG highway. Even Porsche’s own 718 Boxster GTS 4.0, a smaller and lighter sports car, achieves only slightly better figures at 17 MPG city and 24 MPG highway. The slight differences highlight that the 911 buyer isn’t necessarily prioritizing fuel economy above all else. It is about the complete package of performance, style, and driving experience that they find uniquely satisfying. For all all Porsche fuel economy data, visit FuelEconomyHub.com.

Tips to maximize efficiency

While maximizing fuel economy might not be the primary goal for a 911 Targa 4 GTS owner, a few simple practices can help improve mileage without sacrificing too much driving enjoyment. Avoid aggressive acceleration and braking whenever possible. Smooth, deliberate inputs allow the engine management system to operate more efficiently, reducing fuel consumption.

Use the car’s driving modes strategically. The “Normal” mode optimizes for fuel efficiency by adjusting throttle response and shift points. While the “Sport” and “Sport Plus” modes unleash the engine’s full potential, they also consume more fuel. Consider using “Normal” mode for everyday commuting and reserve the more aggressive modes for spirited drives.

Ensure proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressures regularly and inflate them to the recommended levels, found on the sticker located on the driver’s side doorjamb. Proper alignment and balanced tires are essential too.

Minimize idling time. Idling wastes fuel, especially in turbocharged engines. If you anticipate stopping for more than a minute, turn off the engine. Modern cars restart quickly and efficiently, saving fuel and reducing emissions in the process. Also be aware of aerodynamics. Open Targa tops decrease fuel economy, so consider driving with the top on at higher speeds.

Optimizing fuel efficiency does not require sacrificing the joy of driving a 911 Targa 4 GTS. By making a few mindful driving adjustments, owners can extract the most miles from each gallon of fuel while retaining the car’s exhilarating character.
