Powertrain & Engine Architecture
At the heart of the A5 45 TFSI S tronic lies the EA888 2.0-liter turbocharged inline-four engine, specifically coded DKNA. This engine is a cornerstone of the Volkswagen Group’s powertrain strategy, known for its blend of efficiency and performance. The DKNA utilizes direct fuel injection, delivering fuel directly into the combustion chamber for improved combustion efficiency and reduced emissions. The engine also features an integrated exhaust manifold for faster warm-up times and reduced turbo lag. The turbocharger itself is a twin-scroll unit, further enhancing responsiveness. The S tronic transmission is a seven-speed dual-clutch transmission (DCT) offering rapid and smooth gear changes. This transmission is known for its efficiency and ability to provide both comfortable cruising and sporty acceleration.
Driving Characteristics
The 245 horsepower and 272.9 lb-ft of torque produced by the 2.0-liter turbo engine provide brisk acceleration. The 0-60 mph sprint takes approximately 6.1 seconds, making it a genuinely quick coupe. The S tronic transmission plays a crucial role in maximizing this performance, providing seamless shifts and keeping the engine within its optimal power band. Compared to the base 40 TFSI model, the 45 TFSI offers a noticeably more engaging driving experience. While not as raw or focused as the S5, the 45 TFSI strikes a good balance between comfort and performance. The gear ratios in the S tronic are tuned for both acceleration and fuel efficiency, providing a comfortable cruising experience on the highway.
Equipment & Trim Levels
The A5 45 TFSI S tronic typically came well-equipped as standard. Features included Audi’s MMI infotainment system with a 7-inch display, automatic climate control, leather upholstery, and a suite of driver-assistance systems such as lane departure warning and automatic emergency braking. Optional extras included a larger 12.3-inch virtual cockpit display, a premium sound system from Bang & Olufsen, and adaptive cruise control. Interior trim options ranged from brushed aluminum to wood veneers, allowing buyers to personalize the cabin to their taste. Exterior styling options included various wheel designs and paint colors.
Chassis & Braking
The A5 Coupe features a sophisticated suspension system designed to provide a comfortable yet controlled ride. The front suspension utilizes a multi-link setup, while the rear also employs a multi-link design. This configuration allows for precise wheel control and minimizes body roll during cornering. The 45 TFSI model typically came equipped with ventilated front discs and solid rear discs. ABS (Anti-lock Braking System) is standard, along with electronic stability control. The steering is an electromechanical power steering system, providing precise and responsive steering feel.
Market Reception & Comparison
The Audi A5 Coupe 45 TFSI S tronic was generally well-received by automotive critics. It was praised for its stylish design, refined interior, and engaging driving dynamics. Compared to the 40 TFSI, the 45 TFSI offered a significant performance upgrade without a substantial increase in price. Fuel economy was also considered competitive for its class, with combined figures around 37.3 – 35.6 US mpg. However, some critics noted that the ride could be a bit firm on rough roads. Compared to rivals like the BMW 4 Series and Mercedes-Benz C-Class Coupe, the A5 was often seen as offering a more balanced blend of comfort and performance.
Legacy
The EA888 engine, in its various iterations, has proven to be a remarkably reliable powertrain. The S tronic transmission, while requiring more diligent maintenance than a traditional automatic, is also generally considered durable. The A5 Coupe (F5) 45 TFSI S tronic has maintained a solid reputation in the used car market, commanding reasonable prices and attracting buyers who appreciate its blend of style, performance, and technology. Regular maintenance, including oil changes and transmission fluid services, is crucial to ensure the long-term reliability of this powertrain.
