Powertrain & Engine Architecture
The heart of the A4 Avant 2.4i is the BDV engine, a 2.4-liter naturally aspirated V6. This engine is a 30-valve design, featuring dual overhead camshafts (DOHC) and five valves per cylinder. It utilizes a multi-port fuel injection system, delivering fuel directly into the intake ports. The engine’s architecture is longitudinally mounted in the front of the vehicle, driving the front wheels. The Multitronic transmission, a continuously variable transmission (CVT), was a key feature. Unlike traditional automatic transmissions with fixed gear ratios, the Multitronic uses a chain and pulley system to provide a virtually infinite number of gear ratios, optimizing engine efficiency and smoothness. This transmission was known for its smooth operation and ability to keep the engine in its optimal power band.
Driving Characteristics
The 170 horsepower and 230 Nm (169.64 lb-ft) of torque delivered by the 2.4i V6, coupled with the Multitronic transmission, provided a comfortable and refined driving experience. Acceleration from 0-60 mph took approximately 8.7 seconds, which was respectable for the time, but noticeably slower than the more powerful S4 or even the 1.8T models with a manual transmission. The Multitronic transmission prioritized smooth acceleration and fuel efficiency over outright performance. The continuously variable nature of the transmission meant that there were no distinct gear shifts, resulting in a seamless power delivery. However, some drivers found the lack of traditional gear changes to be less engaging than a manual transmission. The engine provided adequate power for everyday driving and highway cruising, but lacked the punch for more spirited driving.
Equipment & Trim Levels
The A4 Avant 2.4i typically came standard with features such as automatic climate control, power windows and locks, and a premium audio system. Interior upholstery was generally cloth, with leather options available as an upgrade. Common optional extras included sunroof, heated front seats, and a navigation system. The trim level often dictated the availability of these options. The 2.4i Avant often served as a stepping stone for buyers wanting more luxury than the base 1.8T models, but without the higher price tag of the S4. Dashboard configuration was typical of the B6 A4, with a clean and functional design.
Chassis & Braking
The A4 Avant (B6) featured an independent multi-link suspension on both the front and rear axles, providing a comfortable ride and good handling characteristics. The 2.4i models typically came equipped with ventilated disc brakes on the front and solid disc brakes on the rear. Anti-lock braking system (ABS) was standard. The suspension was tuned for comfort, prioritizing ride quality over aggressive handling. Stabilizer bars were fitted to both axles to reduce body roll during cornering.
Market Reception & Comparison
The A4 Avant 2.4i was generally well-received by automotive critics. It was praised for its comfortable ride, spacious interior, and refined engine. However, some critics noted that the Multitronic transmission could feel somewhat detached and lacked the responsiveness of a traditional automatic or manual transmission. Compared to the 1.8T models, the 2.4i offered more power and a smoother driving experience, but at a higher price point. Compared to the S4, it offered less performance but was significantly more affordable. Fuel economy was reasonable for a V6 engine, averaging around 25.3 US mpg in combined driving.
Legacy
The BDV engine, while not known for being particularly groundbreaking, proved to be a reliable powerplant when properly maintained. The Multitronic transmission, however, has a more mixed reputation. Early versions of the Multitronic were prone to failures, particularly if the transmission fluid was not changed at the recommended intervals. Later revisions of the transmission proved more durable. Today, the A4 Avant 2.4i represents a relatively affordable entry point into the Audi wagon world. Well-maintained examples are still sought after by enthusiasts who appreciate their blend of practicality, comfort, and refinement. Finding one with a documented service history, particularly regarding the Multitronic transmission, is crucial for potential buyers.
