Technical Specifications

Powertrain & Engine Architecture

At the heart of the 911 Turbo S Cabriolet lies the MA1.71S engine, a 3.8-liter twin-turbocharged flat-six (boxer) engine. This engine utilizes direct fuel injection, a technology that precisely meters fuel directly into the combustion chamber, optimizing combustion efficiency and power output. The twin-turbocharger setup employs variable turbine geometry (VTG) to provide rapid response and minimize turbo lag. The engine produces 560 horsepower at 6,500-6,750 rpm and a substantial 700 Nm (516 lb-ft) of torque available from a low 2,100 rpm all the way to 4,250 rpm. This broad torque curve contributes to the car’s exceptional acceleration. The engine is longitudinally mounted at the rear of the vehicle, a hallmark of the 911 design. The engine is paired with Porsche’s seven-speed PDK (Porsche Doppelkupplung) dual-clutch automatic transmission. This transmission offers incredibly fast and smooth gear changes, enhancing both performance and driving comfort. The PDK transmission allows for both fully automatic operation and manual gear selection via steering wheel-mounted paddles.

Driving Characteristics

The 911 Turbo S Cabriolet delivers a truly exhilarating driving experience. The combination of the powerful engine, the quick-shifting PDK transmission, and the all-wheel-drive system results in breathtaking acceleration. The 0-60 mph sprint takes just 2.9 seconds, and the car can reach a top speed of 197.6 mph. The all-wheel-drive system provides excellent traction, allowing the car to put its power down effectively even in challenging conditions. The Cabriolet configuration adds a unique dimension to the driving experience, allowing occupants to enjoy the sound of the engine and the sensation of open-air motoring. Compared to the standard 991 Carrera Cabriolet, the Turbo S offers a significantly more potent and responsive driving experience. While the Carrera provides a more accessible and comfortable ride, the Turbo S prioritizes performance and driver engagement. The PDK transmission, while offering convenience, provides a more direct and engaging experience than a traditional torque-converter automatic.

Equipment & Trim Levels

The 911 Turbo S Cabriolet came standard with a comprehensive list of features, reflecting its position as the flagship model. Standard equipment included a power-retractable soft top, leather upholstery, heated and ventilated front seats, a premium sound system, and a navigation system. The interior featured carbon fiber trim accents and sport seats with increased bolstering. Optional extras included adaptive cruise control, a sport exhaust system, and various customization options for the interior and exterior. Buyers could choose from a wide range of paint colors, interior leather options, and wheel designs to personalize their vehicle.

Chassis & Braking

The 911 Turbo S Cabriolet features a sophisticated chassis designed to maximize performance and handling. The suspension utilizes Porsche Active Suspension Management (PASM), an electronically adjustable damping system that allows the driver to select between different suspension settings. The car is equipped with ventilated disc brakes on all four wheels, providing exceptional stopping power. The front brakes measure 380 mm in diameter, while the rear brakes are also 380 mm. The braking system is further enhanced by Porsche Ceramic Composite Brakes (PCCB) as an optional extra. The car’s all-wheel-drive system is a sophisticated torque-vectoring system that distributes power between the front and rear axles as needed to optimize traction and stability.

Market Reception & Comparison

The 911 Turbo S Cabriolet was widely praised by automotive critics for its exceptional performance, handling, and refinement. Reviewers lauded the car’s blistering acceleration, its precise steering, and its comfortable ride. Compared to other high-performance convertibles of the time, the 911 Turbo S Cabriolet stood out for its unique combination of performance and practicality. While some competitors offered similar levels of power, few could match the 911’s all-weather capability and its everyday usability. Fuel economy, while not a primary concern for buyers of this vehicle, was respectable for its performance class, averaging around 24.2 US mpg in combined driving.
