Powertrain & Engine Architecture
The heart of the 2013-2015 RS5 Cabriolet is the CFSA engine code, a 4.2-liter naturally aspirated V8. This engine is a direct descendant of the engines used in the R8 sports car, showcasing Audi’s commitment to high-performance naturally aspirated power. It features direct fuel injection (FSI) and a sophisticated valvetrain with variable intake and exhaust timing, allowing for a broad and flat torque curve. The engine produces 450 horsepower at 8,250 rpm and 317 lb-ft of torque between 4,000 and 6,000 rpm. The S tronic 7-speed dual-clutch transmission is standard, providing incredibly fast and smooth gear changes. This transmission is known for its efficiency and responsiveness, contributing to the RS5’s quick acceleration. The quattro all-wheel-drive system distributes power between the front and rear axles, enhancing traction and stability, particularly in adverse weather conditions.
Driving Characteristics
The RS5 Cabriolet with the 4.2 FSI engine and S tronic transmission delivers a thrilling driving experience. Acceleration from 0 to 60 mph takes approximately 4.7 seconds, and it reaches a top speed of 155 mph (electronically limited). The S tronic transmission’s quick shifts and the quattro system’s grip provide excellent launch control and cornering ability. Compared to the standard A5 Cabriolet, the RS5 offers significantly more power and a more aggressive exhaust note. While the automatic transmission is incredibly capable, some enthusiasts prefer the more direct engagement of a manual gearbox, which was not offered in this configuration. The weight distribution is well-balanced, contributing to a neutral handling characteristic.
Equipment & Trim Levels
The RS5 Cabriolet came generously equipped as standard. Interior features included sport seats upholstered in Nappa leather with embossed RS5 logos, a flat-bottomed steering wheel, and carbon fiber trim. Standard exterior features included a unique RS5 front bumper, side skirts, rear diffuser, and quad exhaust outlets. Optional extras included a Bang & Olufsen sound system, adaptive cruise control, and various customization options for interior and exterior finishes. The overall interior design focused on a sporty yet luxurious aesthetic, befitting the RS5’s positioning as a high-performance convertible.
Chassis & Braking
The RS5 Cabriolet features a sport-tuned suspension designed to enhance handling and minimize body roll. The front suspension utilizes independent multi-link technology, while the rear employs an independent trapezoidal link setup. Larger ventilated disc brakes are standard on all four wheels, providing ample stopping power. The braking system is further enhanced by ABS (Anti-lock Braking System) and electronic stability control. Compared to the standard A5 Cabriolet, the RS5 benefits from stiffer springs and dampers, as well as larger stabilizer bars, resulting in a more controlled and responsive ride.
Market Reception & Comparison
The 2013-2015 Audi RS5 Cabriolet was generally well-received by automotive critics. It was praised for its powerful engine, engaging driving dynamics, and luxurious interior. However, some reviewers noted the relatively high fuel consumption and the lack of a manual transmission option. Compared to other high-performance convertibles of the time, such as the BMW M3 Convertible and the Porsche 911 Cabriolet, the RS5 offered a unique blend of performance, luxury, and practicality. The RS5’s all-wheel-drive system provided an advantage in all-weather conditions, while its spacious interior and comfortable ride made it a more suitable daily driver than some of its more focused competitors.
Legacy
The 4.2-liter V8 engine in the RS5 Cabriolet is known for its reliability, although regular maintenance is crucial. The S tronic transmission is also generally reliable, but dual-clutch transmissions can require more frequent servicing than traditional automatics. Today, the 2013-2015 RS5 Cabriolet holds its value well in the used car market, appealing to enthusiasts seeking a high-performance convertible with a naturally aspirated engine. Its combination of power, luxury, and all-weather capability continues to make it a desirable option for those looking for a thrilling and refined driving experience.
