Powertrain & Engine Architecture
At the heart of the 991 Turbo S lies a 3.8-liter twin-turbocharged flat-six engine, designated the MA1.71S. This engine builds upon the foundation of the standard 991 Turbo’s powerplant, but with significant enhancements. These include revised turbochargers, a more efficient intercooler system, and optimized fuel injection. The direct fuel injection system ensures precise fuel delivery, maximizing combustion efficiency and power output. 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, combined with the quick-shifting seven-speed Porsche Doppelkupplung (PDK) dual-clutch transmission, delivers exhilarating acceleration. The PDK transmission features paddle shifters for manual control, but in automatic mode, it intelligently selects gears for optimal performance and efficiency.
Driving Characteristics
The 991 Turbo S delivers a driving experience that is both incredibly fast and remarkably composed. The all-wheel-drive system, coupled with Porsche Torque Vectoring Plus (PTV Plus), provides exceptional traction and stability, allowing the car to put its power down effectively even in challenging conditions. The PDK transmission shifts with lightning-fast precision, eliminating any interruption in power delivery. Compared to the standard 991 Carrera or even the 991 Turbo, the Turbo S offers a significantly more potent and engaging driving experience. The increased power and torque translate into blistering acceleration – 0 to 60 mph in just 2.9 seconds – and effortless high-speed cruising. The suspension, tuned for performance, provides a firm yet controlled ride, minimizing body roll and maximizing cornering grip.
Equipment & Trim Levels
The 991 Turbo S came standard with a comprehensive list of features, reflecting its status as the top-of-the-line 911 variant. These included a sport exhaust system, adaptive suspension management (PASM), dynamic engine mounts, and a sport steering wheel. Interior appointments were equally luxurious, with full leather upholstery, carbon fiber trim, and heated and ventilated sport seats. Optional extras included Porsche Ceramic Composite Brakes (PCCB), a Burmester high-end sound system, and a variety of customization options through Porsche’s “Personalization Plus” program.
Chassis & Braking
The 991 Turbo S features a sophisticated chassis designed to handle its immense power. The suspension utilizes Porsche Active Suspension Management (PASM), which electronically adjusts damping forces to optimize ride comfort and handling. Porsche Dynamic Chassis Control (PDCC) further enhances stability by actively counteracting body roll during cornering. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. The optional PCCB ceramic composite brakes offer even greater stopping performance and resistance to fade.
Market Reception & Comparison
The 991 Turbo S was widely praised by automotive critics for its exceptional performance, handling, and refinement. It was consistently ranked among the fastest and most capable sports cars on the market. Compared to the standard 991 Turbo, the Turbo S offered a noticeable performance advantage, justifying its higher price tag. While fuel economy wasn’t a primary concern for buyers in this segment, the 991 Turbo S delivered respectable figures for a car of its performance caliber, averaging around 24.2 US mpg in combined driving.
Legacy
The 991 Turbo S has proven to be a remarkably reliable and durable sports car. The twin-turbocharged engine, while complex, has demonstrated a strong track record of longevity with proper maintenance. Today, the 991 Turbo S remains a highly sought-after vehicle in the used car market, commanding premium prices. Its combination of blistering performance, luxurious appointments, and Porsche’s renowned engineering quality ensures its continued desirability among enthusiasts for years to come. It represents a high watermark in the evolution of the 911, solidifying its position as an icon of the automotive world.
