Powertrain & Engine Architecture
The heart of the A4 Avant 40 TFSI is the EA888 2.0-liter inline-four cylinder engine, specifically the DMSA engine code. This engine utilizes direct fuel injection and a single twin-scroll turbocharger with intercooling to deliver a balance of power and efficiency. The engine’s cylinder head features four valves per cylinder, contributing to improved breathing and higher output. The mild hybrid system incorporates a 12V belt starter generator (BSG) and a small lithium-ion battery. This system allows for extended start-stop operation, regenerative braking, and a slight power boost during acceleration. The seven-speed S tronic dual-clutch transmission provides quick and smooth gear changes, enhancing both performance and fuel economy. This transmission is known for its efficiency and responsiveness, offering both automatic and manual shift modes.
Driving Characteristics
The 204 horsepower and 236 lb-ft of torque delivered by the 40 TFSI powertrain provide adequate performance for everyday driving. Acceleration from 0-60 mph takes approximately 6.6 seconds, making it competitive within its class. The S tronic transmission’s quick shifts contribute to a responsive driving experience. Compared to the more powerful 45 TFSI variant, the 40 TFSI offers a slightly less aggressive driving experience, prioritizing fuel efficiency over outright speed. The quattro ultra all-wheel-drive system intelligently distributes torque between the front and rear axles, providing enhanced traction in various weather conditions. In normal driving situations, the system primarily operates in front-wheel drive, minimizing fuel consumption. The gear ratios are tuned for a balance of acceleration and highway cruising, with a relatively tall seventh gear for improved fuel economy at higher speeds.
Equipment & Trim Levels
The A4 Avant 40 TFSI quattro ultra typically came standard with features such as Audi’s MMI infotainment system with a 7-inch touchscreen display, automatic climate control, and a leather-wrapped steering wheel. Standard safety features included Audi pre sense basic, lane departure warning, and automatic emergency braking. Optional extras included a larger 10.1-inch MMI touchscreen, a virtual cockpit digital instrument cluster, a premium sound system, and various driver-assistance systems like adaptive cruise control and blind-spot monitoring. Interior upholstery typically consisted of cloth or leather, with various color options available. Trim levels often included “Premium” and “Premium Plus” packages, adding features like heated seats, a panoramic sunroof, and advanced driver-assistance systems.
Chassis & Braking
The A4 Avant features an independent multi-link suspension system at both the front and rear axles, providing a comfortable and controlled ride. The suspension is tuned to balance handling and comfort, offering a good compromise for everyday driving. The front brakes consist of ventilated discs, while the rear brakes utilize solid discs. The quattro ultra system contributes to stability and handling by distributing torque as needed. The steering system is an electromechanical power steering system, providing precise and responsive steering feel. Standard tire size is typically 225/50 R17, with larger wheel and tire options available as upgrades.
Market Reception & Comparison
The A4 Avant 40 TFSI quattro ultra was generally well-received by automotive critics. It was praised for its comfortable ride, refined interior, and efficient powertrain. Fuel economy figures of 32-38 mpg (US) were considered competitive within its segment. Compared to the higher-output 45 TFSI variant, the 40 TFSI offered a more affordable entry point into the A4 Avant range, appealing to buyers who prioritized fuel efficiency and value. The 1.9 TDI diesel variants, popular in Europe, offered even better fuel economy but with a different driving experience and potential concerns regarding diesel emissions regulations. The mild hybrid system was seen as a positive step towards improving fuel efficiency and reducing emissions.
Legacy
The EA888 engine family, including the 2.0-liter unit found in the A4 Avant 40 TFSI, has a reputation for reliability when properly maintained. The S tronic transmission is also generally reliable, although regular servicing is crucial. As a used car, the A4 Avant 40 TFSI offers a compelling combination of practicality, comfort, and technology. Common issues reported by owners include occasional problems with the infotainment system and minor electrical glitches. However, overall reliability is considered good, making it a popular choice in the used car market. The integration of mild hybrid technology represents a step towards electrification, paving the way for future Audi models with more advanced hybrid and electric powertrains.
