Powertrain & Engine Architecture
At the heart of the 991.2 Carrera S Cabriolet lies the MA2.01 or MA2.02 3.0-liter twin-turbocharged flat-six engine. This represented a significant departure from the naturally aspirated engines of previous 911 generations. The move to turbocharging allowed for increased power and torque output while simultaneously improving fuel efficiency. The engine utilizes direct fuel injection, ensuring precise fuel delivery for optimal combustion. The flat-six configuration, also known as a boxer engine, contributes to a low center of gravity, enhancing handling characteristics. The PDK 7-speed dual-clutch transmission provides incredibly rapid and smooth gear changes, contributing to the car’s impressive acceleration. The PDK offers both fully automatic and manual shifting modes, allowing the driver to tailor the driving experience to their preference.
Driving Characteristics
The 991.2 Carrera S Cabriolet with the PDK transmission delivers a remarkably refined yet engaging driving experience. The twin-turbocharged engine provides a broad torque curve, with peak torque of 500 Nm (368.78 lb-ft) available from 1700 to 5000 rpm. This translates to strong acceleration in any gear, making overtaking effortless. Compared to the base Carrera, the ‘S’ model offers noticeably more power and a more responsive throttle. While not as raw or visceral as the manual transmission variants, the PDK provides incredibly quick shifts and allows the driver to maintain focus on the road. The Cabriolet configuration adds a slight weight penalty compared to the coupe, but the impact on performance is minimal. The suspension is well-tuned, providing a comfortable ride while maintaining excellent body control.
Equipment & Trim Levels
The Carrera S Cabriolet came standard with a comprehensive list of features, including leather upholstery, a power-adjustable driver and passenger seat, automatic climate control, a touchscreen infotainment system with navigation, and a high-quality sound system. Optional extras were plentiful, allowing buyers to personalize their vehicle. Popular options included sport seats, a sport exhaust system, adaptive suspension (PASM), and various interior trim packages. The Cabriolet also featured a fully automatic retractable soft top, which could be opened or closed in approximately 13 seconds at speeds up to 50 km/h (31 mph).
Chassis & Braking
The 991.2 Cabriolet utilizes a lightweight chassis construction, incorporating aluminum in key areas to minimize weight. The suspension features independent McPherson struts at the front and a multi-link setup at the rear. The Carrera S models benefited from a slightly stiffer suspension setup compared to the base Carrera, further enhancing handling. Braking duties are handled by ventilated discs on all four wheels, providing ample stopping power. Porsche’s ABS (Anti-lock Braking System) and stability control systems are standard, enhancing safety and driver confidence.
Market Reception & Comparison
The 991.2 Carrera S Cabriolet was widely praised by automotive critics for its performance, handling, and refinement. The twin-turbocharged engine was lauded for its power and responsiveness, while the PDK transmission was commended for its smoothness and speed. Compared to the naturally aspirated 991.1 Carrera S, the 991.2 offered improved fuel economy and a broader powerband. The GTS model provided even more performance, but at a higher price point. The 991.2 Carrera S Cabriolet represented a compelling package for buyers seeking a high-performance, open-top sports car.
Legacy
The 991.2 Carrera S Cabriolet has proven to be a reliable and well-regarded sports car. The twin-turbocharged engine, while more complex than its naturally aspirated predecessor, has demonstrated good long-term durability. The PDK transmission is also known for its reliability. On the used car market, these models hold their value well, reflecting their desirability and reputation for quality. Regular maintenance, including oil changes and inspections, is crucial to ensure the continued reliability of these vehicles. The 991.2 Carrera S Cabriolet remains a popular choice for enthusiasts seeking a thrilling and rewarding driving experience.
