17 MPG combined is what you can expect from the 2022 Porsche Cayenne GTS Coupe with its strong 4.0L V8. This is not a Prius competitor. It’s a performance SUV Coupe built for drivers who prioritize thrills and dynamic performance over ultimate fuel efficiency. Buyers eyeing the GTS Coupe aren’t cross-shopping with economy cars. They’re seeking a specific blend of practicality and driving excitement, and they understand that fuel consumption comes with the fun.

City and highway performance

The EPA estimates for the Cayenne GTS Coupe are 15 MPG in the city and 19 MPG on the highway. The city figure reflects the engine’s eagerness to rev and be heavily used for acceleration from a standstill; the GTS Coupe encourages a spirited driving style. The highway number, while still not impressive, benefits from the automatic transmission’s eight gears, allowing the engine to cruise at relatively low RPMs. Even at highway speeds, a heavy foot will quickly bring the mileage closer to the city figure.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Porsche Cayenne GTS Coupe to be $3,400. This is based on driving 15,000 miles per year and using national average fuel prices for premium gasoline. This is just an estimate; factors like driving habits, local fuel prices, and the specific blend of city versus highway driving will significantly impact what you actually spend. Owners who frequently enjoy the GTS Coupe’s performance will likely exceed this $3,400 figure.

Real-world expectations

You shouldn’t expect to consistently achieve the EPA’s numbers. In the real world, the Cayenne GTS Coupe’s fuel economy is highly dependent on driving style. Those who frequently use the V8’s power and acceleration will likely see figures closer to the low end of the EPA range or even below. Conservative driving will yield better results. Gentle acceleration and a focus on maintaining consistent speeds will help, but still won’t likely meet the expectations of other vehicles in this class. A lead foot equates to lower mileage.

How it compares

The Cayenne GTS Coupe is in a middle-of-the-road position for fuel economy compared to its competitors. The BMW X6 M50i, with its 4.4L V8, delivers similar figures in the mid-to-high teens. The Mercedes-AMG GLE 53 Coupe offers slightly better economy, registering just above 20 MPG combined, which may influence buyers. The Range Rover Sport with its supercharged V8 often consumes fuel at a greater rate than the Porsche. Buyers in this segment often prioritize the driving experience and brand appeal over marginal MPG gains. You can review CAYENNE MPG across all years to see how this model compares historically.

Tips to maximize efficiency

Avoid aggressive acceleration. The Cayenne GTS Coupe’s V8 is responsive and begs to be unleashed, but every hard launch and burst of speed hurts fuel consumption. Smooth, gradual acceleration will decrease fuel consumed.

Maintain proper tire inflation. This is important for fuel efficiency for any vehicle, including high-performance SUVs. Underinflated tires increase rolling resistance, forcing the engine to work harder and burn more fuel.

Use the automatic transmission’s higher gears. On the highway, allow the transmission to shift into the highest possible gear to reduce engine RPM and conserve fuel. Manually downshifting is fun, but it hurts fuel mileage.

Reduce unnecessary weight. Carrying excessive cargo adds weight to the vehicle, which requires more energy to accelerate and maintain speed. Remove any unnecessary items from the vehicle to improve fuel economy.

Plan your routes and avoid stop-and-go traffic whenever possible. Constant acceleration and braking in heavy traffic significantly reduce fuel economy. Consider alternative routes or travel times to minimize time spent in congested areas. For all Porsche fuel economy data, see our brand page.
