19 MPG combined is the fuel economy for the 2023 Porsche 911 Targa 4 GTS. Nobody buys this particular 911 for fuel efficiency, they buy it for the blend of open-air driving, all-wheel-drive stability, and the 473-horsepower flat-six engine’s punch. This isn’t just transportation; it’s an experience owners will pay for at the dealership and when refueling.

City and highway performance

The EPA estimates 17 MPG in the city and 22 MPG on the highway. These figures show the trade-offs in a performance vehicle. City driving, with its stop-and-go, increases fuel consumption because of constant acceleration. The Targa 4 GTS’s throttle and power encourage spirited driving, further impacting MPG. On the open road, the eight-speed automatic transmission helps optimize fuel economy at cruising speeds, but the car’s performance capabilities make high speeds tempting.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2023 Porsche 911 Targa 4 GTS at $3,050. This is based on driving 15,000 miles per year, with 55% in the city and 45% on the highway. The calculation also uses the EPA’s assumption of national average fuel prices. Your fuel costs will vary depending on driving habits and local fuel prices, but this provides a benchmark. The Targa 4 GTS demands premium fuel with the highest octane.

Real-world expectations

Expectations are important, anyone considering a 911 Targa 4 GTS should understand that achieving the EPA numbers requires disciplined driving. Aggressive acceleration, Sport or Sport Plus modes, and extended idling will negatively affect fuel economy. Some owners may see figures slightly above the EPA estimates on long highway trips, but most will find themselves near the combined number, or slightly below. Enjoying the car’s performance directly impacts fuel consumption, a compromise most Targa 4 GTS buyers are prepared to make.

How it compares

When comparing the 911 Targa 4 GTS’s fuel economy to similar vehicles, some context is necessary. The BMW M4 Competition xDrive convertible, a competitor in performance and open-air experience, achieves a slightly better 19 MPG combined with its automatic transmission. A Mercedes-AMG C63 S Coupe, without the Targa’s roof, offers similar thrills but lags slightly behind at 18 MPG combined. Even within Porsche, comparing the Targa 4 GTS’s MPG against the 911 Carrera S Cabriolet (21 MPG combined) highlights the trade-off for the GTS model’s added power and all-wheel-drive system. These differences can add up over time. For buyers prioritizing fuel efficiency in a performance car, alternatives exist, but they often sacrifice some of the Targa’s character and capabilities.

Tips to maximize efficiency

While the Targa 4 GTS isn’t primarily about fuel economy, you can take steps to improve your MPG. Avoid aggressive acceleration. The car’s power is available, but smooth acceleration will reduce fuel consumption, especially in city driving.

Anticipate traffic and coast whenever possible. Using the car’s momentum rather than applying the throttle saves fuel. Look ahead and plan your braking; this minimizes hard stops and acceleration.

Proper tire inflation is critical. Check your tire pressures regularly and maintain them at the recommended levels. Under-inflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. This maintenance task can make a difference.

Minimize idling. Modern engines consume fuel even when stationary. If you anticipate a prolonged stop, turn off the engine, particularly if you find yourself idling for longer than a minute. Idling wastes fuel and contributes to emissions.

Consider using the car’s “Normal” driving mode for everyday commuting. Sport and Sport Plus modes enhance throttle response and shift points, but they also prioritize performance over efficiency. Reserve these modes for spirited driving on appropriate roads, and opt for Normal mode when less gas is a concern. To explore all Porsche fuel economy data, check out our site.
