Powertrain & Engine Architecture
The heart of the A5 Sportback 40 TFSI is the DMSA engine, a 2.0-liter turbocharged inline-four cylinder gasoline engine. This engine is part of Audi’s EA888 family, known for its robust design and tuning potential. The DMSA engine utilizes direct fuel injection, delivering fuel directly into the combustion chamber for improved efficiency and power. A single twin-scroll turbocharger, coupled with an intercooler, provides forced induction, boosting output and broadening the torque curve. The engine’s mild hybrid system (MHEV) incorporates a 12V belt starter generator (BSG) and a small lithium-ion battery. This system allows for extended start-stop functionality, regenerative braking, and a slight power assist during acceleration, contributing to improved fuel economy. The engine is paired with Audi’s seven-speed S tronic dual-clutch transmission, known for its quick and smooth shifts. This transmission offers both automatic and manual shift modes, allowing drivers to tailor the driving experience to their preferences.
Driving Characteristics
The 204 horsepower and 320 Nm (236 lb-ft) of torque delivered by the 40 TFSI powertrain provide a balanced driving experience. Acceleration from 0 to 60 mph takes approximately 6.8 seconds, making it adequately quick for everyday driving and highway merging. The S tronic transmission contributes to responsive acceleration, with minimal torque interruption during shifts. Compared to higher-output versions like the S5, the 40 TFSI offers a more relaxed and fuel-efficient driving experience. While it lacks the outright performance of its more powerful siblings, the 40 TFSI provides ample power for most driving situations. The mild hybrid system is largely transparent to the driver, providing subtle improvements in fuel economy without significantly altering the driving feel. The gear ratios are tuned for a balance between acceleration and fuel efficiency, with taller gears for relaxed cruising on the highway.
Equipment & Trim Levels
The A5 Sportback 40 TFSI typically came standard with a comprehensive list of features, including Audi’s MMI infotainment system with a 10.1-inch touchscreen display, Apple CarPlay and Android Auto integration, a digital instrument cluster, and automatic climate control. Standard safety features included Audi pre sense basic, lane departure warning, and automatic emergency braking. Interior upholstery typically consisted of cloth or leatherette, with optional upgrades to full leather available. Trim levels often included options packages that added features such as a premium sound system, navigation, and advanced driver-assistance systems like adaptive cruise control and blind-spot monitoring. Exterior options included various wheel designs, paint colors, and styling packages.
Chassis & Braking
The A5 Sportback 40 TFSI utilizes a sophisticated chassis design featuring independent multi-link suspension at all four corners. This suspension setup provides a comfortable ride while maintaining good handling characteristics. The front suspension incorporates anti-roll bars to reduce body roll during cornering. Braking duties are handled by ventilated disc brakes at the front and solid disc brakes at the rear. The car is equipped with ABS (Anti-lock Braking System) and electronic stability control (ESC) as standard safety features. The steering system is an electric power-assisted rack and pinion system, providing precise and responsive steering feel.
Market Reception & Comparison
The Audi A5 Sportback 40 TFSI Mild Hybrid S tronic was generally well-received by automotive critics. It was praised for its stylish design, comfortable ride, and efficient powertrain. The mild hybrid system was seen as a positive addition, contributing to improved fuel economy without compromising performance. Compared to other trims in the A5 lineup, the 40 TFSI offered a compelling balance of price, performance, and efficiency. It was often seen as a sweet spot for buyers who wanted a premium compact executive car without the higher price tag of the S5. Fuel economy figures of 5.6-6.0 l/100 km (42-39.2 US mpg) were competitive within its segment.
Legacy
The DMSA engine and S tronic transmission pairing have proven to be relatively reliable, with many examples still on the road today. The mild hybrid system, while relatively simple, has also demonstrated good long-term durability. Common maintenance items include regular oil changes, spark plug replacements, and occasional servicing of the dual-clutch transmission. On the used car market, the A5 Sportback 40 TFSI Mild Hybrid S tronic remains a popular choice, offering a blend of style, practicality, and efficiency. Its reputation for reliability and relatively low running costs contribute to its continued appeal.
