24 MPG combined might seem almost irrelevant to buyers of a 2018 Porsche 911 Targa 4. This isn’t a commuter car or a consciously “green” choice; it’s a statement. It’s about open-air thrills, all-wheel-drive confidence, and the unique allure of the Targa top. The fuel economy is simply a side effect, a compromise accepted for the sheer joy this car delivers. These buyers prioritize driving experience above all else, and they’re willing to pay for it at the pump.

City and highway performance

The EPA estimates of 22 MPG in the city and 28 MPG on the highway paint a clearer picture of where this 911 Targa 4 performs best. Stop-and-go driving in the city will naturally take the biggest toll, as the engine works harder to overcome the car’s weight and all-wheel-drive system. However, the highway figure is respectable, suggesting that longer cruises with the Targa top stowed can be surprisingly efficient. The all-wheel-drive system contributes to a heavier car than rear-wheel-drive models, but the trade-off is superior grip and stability, especially in less-than-ideal weather conditions. The seven-speed PDK also plays a role, keeping the engine in its most efficient range during steady-state cruising.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2018 Porsche 911 Targa 4 at $2,400. This figure is based on driving 15,000 miles per year, with a specific percentage allocated to city versus highway driving, and factoring in the national average fuel prices at the time of calculation. It’s a useful benchmark for comparison, but individual fuel costs will vary depending on driving habits, local fuel prices, and the specific grade of premium fuel used. Considering the performance on offer, many owners likely view this as the cost of admission to the Porsche ownership experience.

Real-world expectations

While the EPA figures offer a standardized comparison, your real-world MPG in the 2018 911 Targa 4 will vary. Enthusiastic driving, using the engine’s full potential, will inevitably lead to lower numbers. Conversely, a more conservative driving style, with gentle acceleration and anticipation of traffic flow, can improve fuel economy. The Targa 4 configuration adds weight and complexity compared to a standard 911, which can also impact fuel consumption. Owners who primarily use the car for weekend enjoyment and spirited drives may see figures closer to the city estimate, while those who use it for longer commutes might achieve better highway numbers.

How it compares

Compared to other sports cars in its class, the 2018 Porsche 911 Targa 4’s fuel economy is within the expected range. The Jaguar F-Type Convertible, for example, with its supercharged V6, achieves around 23 MPG combined. The BMW M4 Convertible, another performance-focused option, posts a similar 22 MPG combined rating. Even within the 911 lineup, fuel economy varies. A rear-wheel drive 911 Carrera can achieve slightly better numbers, around 25 MPG combined, showcasing the impact of the all-wheel-drive system in the Targa 4. These comparisons are unlikely to sway Targa 4 buyers, who are drawn to the unique roof design and all-weather capability, but they provide context for the vehicle’s efficiency within its segment. Looking at all Porsche fuel economy data shows how the 911 slots in overall. Understanding the 911 MPG across all years is also helpful.

Tips to maximize efficiency

Even in a performance car like the 911 Targa 4, there are steps you can take to improve fuel economy without sacrificing too much driving pleasure. Smooth acceleration and consistent speed are key. Avoid aggressive starts and stops, and try to maintain a steady pace on the highway, using cruise control when appropriate. The PDK transmission is programmed to shift efficiently, so trust its decisions and avoid excessive manual shifting unless you’re specifically seeking maximum performance.

Regular maintenance is critical for optimal fuel economy. Ensure that your tires are properly inflated to the recommended pressure, as underinflated tires increase rolling resistance and reduce MPG. Keep the car’s engine properly tuned and follow the manufacturer’s recommended service schedule, including oil changes and air filter replacements. A well-maintained engine runs more efficiently, saving you fuel in the long run.

Consider your driving routes carefully. Avoid congested areas and stop-and-go traffic whenever possible. Opt for routes with fewer hills and more consistent speeds. Planning your trips in advance can help you choose the most fuel-efficient path and minimize unnecessary idling. Idling consumes fuel without covering any distance, so avoid it whenever possible.

Finally, be mindful of extra weight. Remove any unnecessary items from the car, as added weight reduces fuel economy. This can include items in the trunk, such as golf clubs or sports equipment, that are not needed for the current trip. Reducing the car’s overall weight allows the engine to work less and improve efficiency.
