Who it suits. Drivers wanting a rear-wheel-drive gasoline Porsche Buyers comfortable with a $3,900 annual fuel estimate

Choose this 911 when rear-wheel drive and a minicompact gasoline format matter more than minimizing fuel spending. Its 21-MPG combined rating is straightforward, while the $3,900 annual EPA estimate sets a substantial running-cost baseline. The automatic gearbox and turbocharged six-cylinder establish the mechanical package. It makes sense for buyers comfortable with that fuel budget, rather than shoppers whose first filter is the lowest possible yearly fuel cost.

What it is

The 2026 Porsche 911 Carrera Cabriolet is a car in the EPA Minicompact Cars class. It uses rear-wheel drive and an automatic transmission.

Power comes from a 3.0-liter turbocharged six-cylinder gasoline engine. The figure that defines its everyday efficiency is 21 MPG combined.

The numbers

The EPA rates it at 18 MPG in city driving and 25 MPG on the highway. The combined rating blends those two conditions into one 21-MPG figure.

Tailpipe emissions are listed at 429 grams of CO2 per mile.

What it costs to run

The EPA annual fuel-cost estimate is $3,900. That estimate applies to its gasoline powertrain and gives you a clear yearly fuel budget.

How it compares

Its 21-MPG combined rating gives you a number to set beside other entries in the Porsche cars list. The figures here do not include another model's MPG, so they do not support a direct winner between cars.

You can also use 21 MPG when checking the fuel-efficient cars list, but no other model's rating is provided here.

Who it suits

This car suits a buyer seeking a rear-wheel-drive Porsche with a gasoline six-cylinder engine and automatic transmission.

It also fits someone willing to plan around an EPA annual fuel estimate of $3,900.

Trade-offs

The 18-MPG city rating is notably below its 25-MPG highway figure, so stop-and-go driving uses more fuel than steady highway travel.

You get rear-wheel drive, a turbocharged six-cylinder gasoline engine, and a 21-MPG combined rating. The same setup carries 429 grams of CO2 per mile and the stated annual fuel cost.

Verdict

Choose this 911 when rear-wheel drive and a minicompact gasoline format matter more than minimizing fuel spending. Its 21-MPG combined rating is straightforward, while the $3,900 annual EPA estimate sets a substantial running-cost baseline. The automatic gearbox and turbocharged six-cylinder establish the mechanical package. It makes sense for buyers comfortable with that fuel budget, rather than shoppers whose first filter is the lowest possible yearly fuel cost.
