19 MPG combined isn’t going to win any fuel efficiency awards, but for the 2022 Porsche Cayenne and Cayenne Coupe equipped with the 3.0L turbocharged six-cylinder engine, it’s a figure most owners readily accept. This isn’t a car purchased for maximizing gas mileage; it’s a Porsche, first and foremost. Buyers want performance, driving dynamics, and the prestige of the brand over outright efficiency. They want a luxurious, sporty SUV (or coupe-styled SUV) that can thrill on a winding road and impress in the school drop-off lane, and fuel economy simply isn’t a top priority.

City and highway fuel economy

The EPA estimates for the 2022 Cayenne/Cayenne Coupe 3.0L are 17 MPG in the city and 22 MPG on the highway. The lower city figure reflects the stop-and-go driving conditions where the engine spends more time idling and accelerating from a standstill. The highway figure is more palatable, as the engine cruises at a more consistent speed. Remember that these figures are estimates under controlled conditions; your actual mileage will vary depending on your driving style, terrain, and vehicle load. Cayenne and Cayenne Coupe owners often live in urban or suburban environments, so the 17 MPG city figure is often more relevant to their everyday lives.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Porsche Cayenne and Cayenne Coupe 3.0L at $3,050. This figure is calculated based on driving 15,000 miles per year, using the EPA’s combined MPG estimate, and assuming a national average fuel price. This is just an estimate. If you drive more than 15,000 miles per year or if fuel prices are higher in your area, you’ll spend more, or if you drive fewer miles or fuel prices are lower, you’ll spend less. The $3,050 figure offers a useful point of comparison against other vehicles in this class and enables you to consider your individual driving habits.

Real-world expectations

While the EPA numbers provide a baseline, real-world fuel economy for the Cayenne and Cayenne Coupe 3.0L can fluctuate quite a bit. Aggressive driving, frequent short trips where the engine doesn’t reach optimal temperature, and extensive idling can all negatively impact fuel efficiency. Some owners have reported achieving numbers close to the EPA estimates with careful driving and a mix of city and highway miles. However, others who frequently indulge in the car’s performance capabilities or primarily drive in congested urban areas find their average MPG to be lower. It’s always best to expect that this is a performance-oriented vehicle.

How it compares

Compared to its rivals, the 2022 Cayenne/Cayenne Coupe 3.0L’s fuel economy is about average for its class. For example, the BMW X5 sDrive40i gets 21 MPG combined, while the Mercedes-Benz GLE 350 earns 22 MPG combined. The Audi Q7 45 TFSI clocks in at 21 MPG combined. The slight differences in MPG may not seem significant, but they can add up over the course of a year. For many Cayenne buyers, the marginal difference in fuel cost is a small price to pay for the Porsche’s superior performance and driving experience. These buyers often cross-shop models, and knowing the all Porsche fuel economy data can be crucial to the decision-making process. You can also research the CAYENNE MPG across all years.

Tips to maximize fuel economy

Even though the Cayenne isn’t primarily designed for fuel efficiency, there are steps you can take to optimize its gas mileage. Avoid aggressive acceleration and braking. Gentle and deliberate inputs will significantly reduce fuel consumption. The Cayenne’s eight-speed automatic transmission is designed to shift smoothly and efficiently; let it do its job without excessive throttle inputs.

Use the Porsche Drive Mode Selector strategically. The “Normal” mode prioritizes fuel efficiency by optimizing throttle response and shift points. The “Sport” and “Sport Plus” modes offer enhanced performance, but they also significantly increase fuel consumption. Reserve these modes for spirited driving and stick to “Normal” for everyday commuting.

Ensure that your tires are properly inflated. Underinflated tires increase rolling resistance, which negatively impacts fuel economy. Check your tire pressure regularly using a reliable gauge and inflate them to the recommended pressure listed on the driver’s side doorjamb.

Reduce unnecessary weight. Carrying extra cargo adds to the vehicle’s load and decreases fuel efficiency. Remove any items you don’t need from the trunk or cargo area to minimize weight and reduce fuel consumption.

Maintain your Cayenne/Cayenne Coupe according to the manufacturer’s recommendations. Regular oil changes, air filter replacements, and other scheduled maintenance items can help keep the engine running smoothly and efficiently. A well-maintained engine burns fuel more efficiently, which improves gas mileage.
