The Audi A4 (B5) facelift, produced from 1999 to 2000, represented a significant mid-cycle refresh of Audi’s popular compact executive car. Among the various engine and drivetrain configurations offered, the 2.4-liter V6 30V (165 hp) paired with the quattro all-wheel-drive system and a five-speed Tiptronic automatic transmission occupied a compelling position in the lineup. This variant aimed to deliver a blend of performance, refinement, and all-weather capability, appealing to buyers seeking a more premium experience than the base four-cylinder models, but without the higher price tag of the more potent S4. It was built on the Volkswagen Group’s B5 platform (Typ 8D), shared with the Volkswagen Passat.

Powertrain & Engine Architecture
The heart of this A4 variant was the 2.4-liter V6 engine, identified by engine codes AML, APS, or ARJ depending on the specific market and production year. This engine featured a 60-degree V-angle, contributing to a relatively compact design for a six-cylinder unit. It employed a dual overhead camshaft (DOHC) valvetrain with five valves per cylinder (three intake, two exhaust), maximizing breathing efficiency. Fuel delivery was handled by a multi-port fuel injection system, providing precise fuel metering for optimal combustion. The engine produced 165 horsepower at 6000 rpm and 230 Nm (169.64 lb-ft) of torque at 3200 rpm.
The Tiptronic five-speed automatic transmission offered a degree of driver control, allowing for manual gear selection alongside the conventional automatic mode. This transmission was known for its smooth shifts and responsiveness, although it wasn’t as sporty or efficient as a manual gearbox. The quattro all-wheel-drive system utilized a Torsen center differential, distributing torque between the front and rear axles based on traction conditions. This provided enhanced stability and grip, particularly in adverse weather.
Driving Characteristics
The 2.4 V6 with the Tiptronic transmission delivered a comfortable and refined driving experience. Acceleration to 60 mph took around 9.5 seconds, which was respectable for the era, but noticeably slower than the manual transmission or the more powerful 2.8 V6 models. The Tiptronic transmission, while smooth, did introduce some power loss compared to a manual. The gear ratios were tuned for everyday usability rather than outright performance. The quattro system provided excellent traction, inspiring confidence in slippery conditions. The suspension, tuned for comfort, absorbed bumps well, but didn’t offer the same level of sporting engagement as the S4.
Equipment & Trim Levels
The 2.4 V6 quattro Tiptronic typically came well-equipped, positioning it as a mid-range offering within the B5 A4 lineup. Standard features often included automatic climate control, power windows and locks, a driver and passenger airbag, and an upgraded audio system. Interior upholstery was typically cloth, although leather options were available. Optional extras included sunroof, heated front seats, and upgraded alloy wheels. The dashboard layout was typical of Audi at the time, characterized by a clean, functional design with intuitive controls.
Chassis & Braking
The B5 A4 featured a fully independent suspension system, with wishbone setups at the front and a double wishbone configuration at the rear. This provided a good balance of ride comfort and handling. The 2.4 V6 models were equipped with ventilated disc brakes at the front and solid disc brakes at the rear. Anti-lock braking system (ABS) was standard. Steering was via a hydraulic power steering rack and pinion system, offering precise and responsive control.
Market Reception & Comparison
The 2.4 V6 quattro Tiptronic A4 was generally well-received by automotive critics. It was praised for its refined engine, comfortable ride, and all-weather capability. However, some reviewers noted that the Tiptronic transmission dulled the driving experience compared to the manual gearbox. Compared to the 1.8T models, the V6 offered more power and a smoother engine character, but at a higher price point. The 2.8 V6 quattro provided even more performance, but came with a significant price premium. Fuel economy was reasonable for a V6 engine, but not as efficient as the four-cylinder options.
Legacy
The 2.4 V6 engine in the B5 A4 proved to be a relatively reliable unit, although regular maintenance is crucial. The Tiptronic transmission, while generally durable, can be prone to issues with age, particularly if not serviced properly. Today, these cars are increasingly sought after by enthusiasts who appreciate their classic Audi styling and robust build quality. Finding well-maintained examples can be challenging, but they offer a compelling alternative to more modern vehicles, providing a unique blend of comfort, performance, and all-weather capability. The B5 A4, particularly the V6 variants, are remembered as a pivotal model in establishing Audi’s reputation for building premium, technologically advanced automobiles.
