2017 Porsche Cayenne S e-Hybrid: the full review

The Cayenne S e-Hybrid combines plug-in hybrid power with a listed 14-mile EPA range and 46 MPGe combined. Its listed EPA annual fuel cost is $3,750.

Overview

The 2017 Porsche Cayenne S e-Hybrid is an all-wheel-drive SUV with a plug-in hybrid powertrain. It pairs a 3.0-liter supercharged six-cylinder engine and automatic transmission with the ability to charge from an external power source. Its EPA figures show both electric-energy and gasoline use: 46 MPGe combined and 22 MPG combined. The EPA-rated electric range is 14 miles, so the plug-in portion covers a limited distance before gasoline use becomes central to longer journeys.

The EPA classifies it as a Standard Sport Utility Vehicle 4WD. Its combined fuel economy is supported by ratings of 21 MPG in city driving and 24 MPG on the highway. Tailpipe carbon dioxide is listed at 258 grams per mile. Those figures give buyers a clearer picture of the trade-off: this is a gasoline SUV with plug-in capability, not a long-range electric vehicle.

Key features

Plug-in hybrid powertrain: Gasoline engine paired with external charging capability.
Engine and transmission: 3.0-liter supercharged six-cylinder engine with an AM8 automatic transmission.
All-wheel drive: The EPA listing identifies the drivetrain as all-wheel drive.
Electric range: EPA-rated range of 14 miles.
Charging: Listed charging time is three hours at 240 volts.

Energy consumption is listed at 71 kWh per 100 miles. That figure should be considered alongside the 46 MPGe combined rating and the separate gasoline economy figures, rather than as a measure of the vehicle's gasoline use alone.

Pricing

No purchase price or lease price is listed in the available details. The EPA-estimated annual fuel cost is $3,750 USD. This running-cost figure provides a useful point of comparison, but actual costs will depend on gasoline and electricity prices and how the vehicle is driven and charged.

Who it's for

The Cayenne S e-Hybrid may suit shoppers who want an SUV with all-wheel drive and the option to charge for shorter trips, while retaining a gasoline engine for journeys beyond its 14-mile EPA electric range. The three-hour charge-time listing at 240 volts gives a reference for charging planning, though the information here does not specify charging equipment or other charging conditions.

For buyers comparing operating costs, the key figures to weigh together are the 46 MPGe combined rating, 22 MPG combined gasoline rating, 71 kWh per 100 miles energy use, and $3,750 USD estimated annual fuel cost. Those figures describe different parts of the vehicle's energy use and are not interchangeable.

Pros and cons

Pros: Plug-in hybrid capability, all-wheel drive, a 14-mile EPA electric range, and a listed three-hour charge time at 240 volts.
Cons: The electric range is limited, and the listed combined gasoline economy is 22 MPG. Annual fuel cost is estimated at $3,750 USD.

Alternatives

For a broader look at the marque, see Porsche cars. The listed alternatives are 2026 Porsche 911 models rather than direct SUV comparisons: 2026 Porsche 911 Carrera, 2026 Porsche 911 Carrera 4 GTS, 2026 Porsche 911 Carrera 4 GTS Cabriolet, 2026 Porsche 911 Carrera 4S, 2026 Porsche 911 Carrera 4S Cabriolet, 2026 Porsche 911 Carrera Cabriolet, 2026 Porsche 911 Carrera GTS, and 2026 Porsche 911 Carrera GTS Cabriolet.

Verdict

The 2017 Cayenne S e-Hybrid combines an all-wheel-drive SUV layout and gasoline engine with plug-in charging and a modest EPA-rated electric range. Its strongest case is for drivers whose regular trips can make use of that 14-mile range and who value retaining gasoline capability for longer travel. Its running-cost picture should be judged against the 22 MPG combined rating and $3,750 USD estimated annual fuel cost, alongside the electricity-use figures. Buyers seeking extensive electric-only travel will find that the listed range is limited.
