Porsche Fuel Economy
55 vehicles with EPA fuel economy data.
EPA publishes fuel-economy figures for 55 Porsche model years in our index, spanning 8 models from 2015 to 2025. Across those, combined economy averages 24.3 MPG.
The most efficient is the 2024 Porsche 911 at 32 MPG combined; the least is the 2025 Porsche Cayenne at 19 MPG — a spread of 13 MPG across the range. At 15,000 miles a year that gap is worth roughly $2,359 a year in fuel.
Fuel types represented: premium gasoline, regular gasoline. EPA figures come from a standardized test cycle, so they are comparable between vehicles but will not match what any individual driver sees.
