About this car

The 2017 Porsche 911 Turbo S Cabriolet delivers open-air exhilaration wrapped in the iconic silhouette of Porsche’s flagship 911. Finished in Night Blue Metallic with a contrasting Graphite Blue/Chalk interior, this low-mileage example shows just 25,016 miles and retains the refined presence expected of a Turbo S Convertible.

Power comes from a 3.8L H6 engine paired with all-wheel drive and an automatic transmission, producing the effortless acceleration and composed handling that define the Turbo S. With a convertible top that disappears in seconds, the car blends everyday usability with supercar performance, offering 19 mpg city and 24 mpg highway ratings while maintaining the distinctive flat-six soundtrack.

Every detail, from the wide-body stance measuring 79.7 inches across to the four-passenger cabin, underscores the model’s blend of grand-touring comfort and track-ready capability.

About the Porsche 911 Turbo S 991

Production: 2011–2019
Cylinders: 6
Powertrain: Combustion

The Porsche 911 Turbo S (991 generation) was produced between 2012 and 2019 as part of the seventh-generation 911 lineup. This model, available in both coupe and cabriolet variants, is a high-performance flagship of the 911 range, with production numbers estimated at around 10,000-12,000 units worldwide across its variants, making it relatively rare compared to standard 911 models. It is powered by a 3.8-liter twin-turbocharged flat-six engine, delivering between 560 hp (early models) and 580 hp (later 991.2 facelift models from 2016), paired with a 7-speed PDK dual-clutch transmission.

For exotic car collectors, the 991 Turbo S stands out due to its advanced technology, including active aerodynamics, rear-wheel steering, and all-wheel drive, enhancing its performance and drivability. It achieves 0-60 mph in as little as 2.8 seconds, with a top speed of around 205 mph. Its historical significance lies in blending cutting-edge engineering with the iconic 911 design, while limited-run special editions like the Exclusive Series (991.2) add to its appeal. Value trends show steady appreciation, especially for low-mileage or special-edition examples, with prices often exceeding $150,000 in the collector market as of recent years.
