The available specifications focus on powertrain, drive type and EPA fuel economy. They do not provide performance figures, cabin or cargo measurements, equipment details, or convertible-top specifications, so those cannot be assessed here.

Who it's for

This Carrera 4 Cabriolet may suit buyers comparing older gasoline-powered minicompacts who want an automatic transmission and four-wheel or all-wheel drive. Its EPA ratings help frame fuel use: 16 mpg city, 24 mpg highway and 19 mpg combined. Buyers weighing ongoing fuel spending can also use the EPA annual fuel-cost estimate of $4,350 as a reference point, rather than treating it as a complete ownership budget.

It is also a useful entry in a model comparison for shoppers prioritizing documented running-cost information. The listed figures do not establish maintenance expenses, insurance costs, reliability, or current market value.

Pros and cons

Pros: EPA city, highway and combined mileage figures are available, along with tailpipe CO2 and annual fuel cost. The specifications identify the engine, automatic transmission and all-wheel-drive configuration.
Cons: The EPA estimates are 16 mpg city and 19 mpg combined, and the listed annual fuel cost is $4,350. Other ownership expenses and equipment details are not provided.

Alternatives

For current 911 comparisons, the 2026 Porsche 911 Carrera and 2026 Porsche 911 Carrera Cabriolet provide two model names to consider. Buyers looking at Carrera 4 variants can compare the 2026 Porsche 911 Carrera 4 GTS, 2026 Porsche 911 Carrera 4 GTS Cabriolet, 2026 Porsche 911 Carrera 4S and 2026 Porsche 911 Carrera 4S Cabriolet.

Other listed 2026 choices include the 2026 Porsche 911 Carrera GTS and 2026 Porsche 911 Carrera GTS Cabriolet. Their detailed specifications are not included here, so a direct comparison of fuel economy or equipment would require those figures.

Verdict

The 2006 Porsche Carrera 4 Cabriolet is defined in the available data by its 3.6-liter six-cylinder gasoline engine, five-speed automatic transmission and four-wheel or all-wheel drive. Its EPA ratings are 16 mpg city, 24 mpg highway and 19 mpg combined, with tailpipe emissions of 467.74 grams of CO2 per mile and an annual fuel-cost estimate of $4,350. Those numbers make fuel use a central consideration for buyers comparing it with other cars. The facts here support a running-cost and powertrain overview, but not a broader judgment about performance, comfort or equipment.
