Powertrain & Engine Architecture
At the heart of the A5 45 TFSI Cabriolet lies the EA888 2.0-liter turbocharged four-cylinder engine, specifically the DKNA variant. This engine is a cornerstone of the Volkswagen Group’s powertrain strategy, known for its blend of efficiency and performance. It utilizes direct fuel injection and an integrated exhaust manifold for improved thermal management and responsiveness. The turbocharger, often a twin-scroll design, minimizes turbo lag and delivers a broad torque curve. The engine produces 245 horsepower at 5000-6500 rpm and 272.9 lb-ft of torque between 1600-4300 rpm. This power is delivered to all four wheels via Audi’s quattro ultra all-wheel-drive system. This system intelligently switches between front-wheel drive and all-wheel drive as needed, optimizing fuel economy. The S tronic 7-speed dual-clutch transmission provides rapid and smooth gear changes, enhancing the driving experience.
Driving Characteristics
The 45 TFSI Cabriolet offers a refined and engaging driving experience. The 245 hp engine provides ample power for both relaxed cruising and spirited driving. Acceleration from 0 to 60 mph takes approximately 6.2 seconds. The S tronic transmission contributes to this performance with its quick shifts and precise control. Compared to the base 40 TFSI model, the 45 TFSI offers a noticeable increase in power and responsiveness. While not as aggressively tuned as the S5 Cabriolet, it strikes a good balance between performance and comfort. The quattro ultra system provides excellent traction in various conditions, enhancing stability and confidence. The gear ratios are tuned for a blend of acceleration and fuel efficiency, with taller gears for highway cruising.
Equipment & Trim Levels
The A5 45 TFSI Cabriolet typically came well-equipped as standard. Features included leather upholstery, three-zone automatic climate control, Audi’s MMI infotainment system with a 7-inch display, and a suite of driver-assistance systems such as Audi pre sense basic. Optional extras included a larger MMI touch response system with a 10.1-inch display, a Bang & Olufsen sound system, navigation, and various driver-assistance packages. Interior trim options ranged from brushed aluminum to wood veneers, allowing for personalization. The Cabriolet also featured a fully automatic acoustic soft top, designed for quiet operation and all-weather usability.
Chassis & Braking
The A5 Cabriolet utilizes a sophisticated chassis design, featuring an independent multi-link suspension at both the front and rear. This setup provides a comfortable ride while maintaining precise handling. The steering is a speed-sensitive electromechanical system, offering a balance of assistance and feedback. Braking duties are handled by ventilated discs at the front and solid discs at the rear, equipped with ABS and electronic brake-force distribution. The chassis is reinforced to compensate for the lack of a fixed roof, ensuring structural rigidity and minimizing body flex.
