Who it suits. Drivers who want a two-seat rear-wheel-drive car Highway-focused driving Buyers comfortable with gasoline running costs

The 2025 Porsche 718 Cayman fits buyers who specifically want two seats and rear-wheel drive in a gasoline car. Its 24 MPG combined rating is workable for mixed driving, with 27 MPG on the highway and 21 MPG in the city. Budget $3,400 a year for fuel under the EPA estimate, and expect 375 grams of tailpipe CO2 per mile. If those running numbers and the two-seat format suit your routine, the Cayman is a clear match; if not, another chart entry may fit your miles better.

What it is

The 2025 Porsche 718 Cayman is a two-seat car running on gasoline. It sends power to the rear wheels through an automatic transmission.

Its powertrain uses a 2.0-liter turbocharged four-cylinder engine. Its combined rating is 24 MPG.

The numbers

The EPA rates the Cayman at 21 MPG in city driving and 27 MPG on the highway. The combined figure is 24 MPG, blending those two types of use.

Those numbers describe gasoline mileage, not electric range or charging. Tailpipe emissions are 375 grams of CO2 per mile.

What it costs to run

EPA estimates yearly fuel cost at $3,400. Your actual bill will change with miles driven, gasoline prices and how much of your driving is in town or on the highway.

How it compares

Use the Cayman's 24 MPG combined rating when comparing it with other two-seat cars. The city and highway figures show where its mileage changes with the type of trip.

You can also line it up with other Porsche cars or the wider fuel-efficient cars list using the same combined-MPG measure.

Who it suits

This car suits a buyer who wants a two-seat gasoline car with rear-wheel drive and accepts the running cost that comes with its 24 MPG combined rating.

Its 27 MPG highway figure may matter more to someone whose driving is mostly longer trips than to a driver who spends most miles in town.

Trade-offs

The Cayman uses gasoline and returns 21 MPG in city driving, so urban miles are less efficient than highway miles. EPA annual fuel cost is $3,400.

You get a two-seat body and rear-wheel drive, along with a 2.0-liter turbocharged four-cylinder and automatic transmission. Those fixed choices define the car's space, drivetrain and fuel use.

Verdict

Choose the 718 Cayman if a two-seat, rear-wheel-drive layout is central to your decision and 24 MPG combined fits your budget. Its 27 MPG highway rating helps on longer runs, while the 21 MPG city rating matters in stop-and-go use. Plan around the EPA's $3,400 yearly fuel estimate rather than treating the mileage figure alone as the full cost. The result is a gasoline car whose practical question is whether its layout and fuel bill match your driving.
