17 MPG combined won’t win any fuel economy awards, but for the 2019 Porsche Cayenne Turbo with its 4.0L V8, it’s an accepted reality. This isn’t a vehicle purchased for its frugality. Cayenne Turbo buyers prioritize blistering acceleration, precise handling, and imposing presence above all else. Fuel consumption is simply part of the cost of owning a high-performance SUV from Porsche.

City and highway performance

The EPA estimates the 2019 Cayenne Turbo at 15 MPG in the city and 19 MPG on the highway.

The city figure reflects stop-and-go driving conditions, where the engine spends more time idling and accelerating from a standstill. The highway number represents consistent speed cruising both figures are derived from standardized testing, but provide a baseline for comparing this vehicle to others in its class. In real-world conditions, aggressive driving will certainly reduce these numbers, while a more judicious approach might yield slightly better results on longer highway stretches.

Annual fuel cost

The EPA calculates the annual fuel cost for the 2019 Porsche Cayenne Turbo at $3,400. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway. The calculation also uses the national average fuel price at the time of testing.

Keep in mind that this is an estimate; your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and fluctuating fuel prices. The Cayenne Turbo also requires premium fuel, further contributing to its higher running costs. Remember that this number should be considered when looking at CAAYENNE MPG across all years and trims.

Real-world expectations

Don’t expect to consistently achieve the EPA’s numbers, especially if you take full advantage of the Cayenne Turbo’s performance.

The allure of that twin-turbocharged V8 is difficult to resist, and frequent bursts of acceleration will undoubtedly impact fuel consumption. Drivers who frequently navigate congested urban environments or enjoy spirited weekend drives should anticipate fuel economy closer to the city estimate, or even slightly lower. Those who primarily use the Cayenne Turbo for longer highway commutes might see figures closer to, or even slightly above, the 19 MPG highway estimate. However, consistent observance of speed limits, gentle acceleration, and minimized idling are crucial for maximizing fuel efficiency. Remember that the Cayenne Turbo’s weight and standard all-wheel drive system also contribute to its fuel consumption.

How it compares

Compared to its competitors, the 2019 Porsche Cayenne Turbo’s fuel economy is similar to other high-performance SUVs. The BMW X5 M, for example, is rated at 16 MPG combined. The Mercedes-AMG GLE 63 S Coupe achieves a similar 17 MPG combined. These vehicles offer comparable levels of performance and luxury, so their fuel consumption tends to be similar.

A less powerful but still luxurious SUV like the Range Rover Sport with its supercharged V6 achieves slightly better fuel economy in the low 20s. This comparison is important to buyers who are cross-shopping these vehicles and want to understand the trade-offs between performance and fuel efficiency. If fuel economy is a primary concern, exploring a hybrid or plug-in hybrid SUV from any of these brands is a far better bet. Check all Porsche fuel economy data to see how this vehicle compares to more fuel-efficient models in the Porsche lineup.

Tips to Maximize Efficiency

Maintain a steady speed and avoid aggressive acceleration. The Cayenne Turbo encourages spirited driving, but gentler inputs on the throttle will significantly improve fuel consumption, especially in urban settings. Anticipate traffic flow and avoid unnecessary braking. This allows the engine to maintain a more consistent RPM, reducing fuel consumption during acceleration.

Ensure that your tires are properly inflated. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended specifications.

Minimize idling time. Idling burns fuel without covering any distance. If you are stopped for more than a minute, turn off the engine. The Cayenne Turbo has an automatic start-stop feature, use it! It’s designed to save fuel in these situations, just be sure to familiarize yourself with how it operates, and remember it can be deactivated if desired.

Reduce weight. Carrying unnecessary cargo adds weight to the vehicle, which increases fuel consumption. Remove any items from the vehicle that are not essential. Every pound counts, especially in a performance SUV like the Cayenne Turbo.

Consider using the Porsche’s driving modes. Select the “Normal” or “Eco” mode when maximum performance isn’t required. These modes optimize engine and transmission settings for improved fuel efficiency. Even in these modes, the Cayenne Turbo offers plenty of power for everyday driving.
