Audi A4 Classic Cars for Sale

History of the Audi A4

First launched in 1994 as the successor to the Audi 80, the A4 marked a new era for Audi's mid-size segment. Built on the Volkswagen Group's B platform, the A4 reflected significant advancements in build quality, safety, and technology. Its internal designation, starting with B5, continued Audi’s tradition of meticulous incremental evolution. The model range extended through generations B5, B6, B7, B8, and B9, with the A4 continuously setting standards for refinement and technical sophistication. Over three decades, it established itself as a mainstay among compact executive cars, introducing innovative features with each new iteration.

Model Series Evolution

The genealogy of the A4 begins with the B5 (1994–2001), which took over from the iconic Audi 80. Each subsequent series brought innovations: the B6 introduced sharper styling and improved chassis rigidity; the B7 was notable for safety improvements and new performance models; the B8 (2007–2015) expanded dimensions and comfort technologies; the B9 continues to offer efficient engines and advanced driver assistance systems. Sporty derivatives, including the S4 and RS4, have always provided high-performance alternatives, while the Avant estate and Cabriolet versions widened the appeal.

Highlights of the Audi A4

What distinguishes the A4 is its unparalleled range of options. Petrol, diesel, and even LPG engines are available, with everything from economical four-cylinders to powerful V8s in the S4/RS4 models. Audi’s quattro all-wheel-drive system is available across many versions, while front-wheel drive remains standard in most. Notable luxury and safety equipment features in the A4 include advanced climate control, heated seats, high-quality audio systems from Bose and Bang & Olufsen, navigation with MMI, and a comprehensive array of driver assistance technologies.

Comfort is uncompromised, with options such as memory seats, ambient lighting, and advanced infotainment available across generations. More recent models feature advanced emissions control devices, including Euro 6 compliance and start-stop technology. Many Avants offer immense practicality with folding rear seats, large luggage capacity, and versatile cargo accessories.

Technical Data

Special Editions and Collectible Models

Of particular note are the RS4 models, especially the B5 RS4 Avant, which built its reputation with a 2.7-litre V6 Biturbo engine and a production run limited to around 6,000 examples. These vehicles, engineered by quattro GmbH (now Audi Sport GmbH), combine muscular design with advanced suspension (lowered by 20 mm) and powerful brakes. S4 variants and S-Line packages offer special trim details, exclusive colours, enhanced interiors, and bespoke alloy wheel options. Many special editions feature unique interior trims—carbon fibre, exclusive stitching, and Recaro sport seats—and distinct exterior packages, such as aluminium mirror caps or matt aluminium styling.

Weak Spots and Common Issues

Common to many A4 generations are standard mechanical wear items—timing belts, suspension components, and dual-mass flywheels on some engines. Turbocharged engines may require attention to oil quality and timely service intervals. quattro drivetrain components and advanced electronics in later models necessitate regular inspection. Interior wear, especially on bolsters and switches, can be found in higher-mileage examples. RS4 and S4 models can encounter more frequent servicing needs due to high-performance parts. Checking for complete service history, including timing belt changes and documented maintenance, is advisable.

Engine and Performance, Transmission and Handling

Performance in the A4 covers an exceptional bandwidth. Entry-level petrol and diesel models deliver refined ride quality and efficiency. quattro drive variants provide superior traction, especially appreciated in poor weather or spirited driving. High-performance models like the S4 and RS4 stand out: The RS4 B5 achieves 0–100 km/h comfortably under 5 seconds, supported by the robust 2.7 V6 Biturbo, while later B7 and B8 RS4s feature a naturally aspirated or TFSI V8, continuing the A4’s commitment to engine innovation. Transmission options span from lively manuals to responsive automatics and dual-clutch transmissions, with performance models featuring dedicated sport configurations.

• A4 B5 8D5: First A4 generation, large supply and demand, classic status rising
• A4 B7 8E: Advanced safety, new S4/RS4, strong demand
• RS4 B5 Avant: 2.7 V6 Biturbo, quattro, iconic for Audi enthusiasts
• S4/RS4 (all generations): Benchmark for performance wagons

Interior, Comfort, Exterior and Design

Audi A4 interiors stand out for solid ergonomics, material quality, and attractive trim selections. Depending on model, you find full leather, partial leather, Alcantara, carbon, aluminium, or wood inlays, and ambient LED lighting in later cars. RS and S models include Recaro sport seats, distinctive instrument clusters with model-specific gauges, and flat-bottom steering wheels. Special exterior paint colours such as Avus Silver, Daytona Grey, Phantom Black, Imola Yellow, and Sonoma Green give collectors unique options.

Accessories abound, from panoramic sunroofs, privacy glazing, rear seat “skisacks”, and removable net partitions in Avant models, to high-end sound systems and adaptive xenon/LED lighting. RS models are easily recognised by their flared arches, unique sill extensions, and larger air intakes. Cabriolet versions feature electro-hydraulic soft tops, often with full automation.

Other Noteworthy Features

Audi A4s often come meticulously documented, with service booklets and multiple keys. Many include ISOFIX mounts for child seats, and advanced optional equipment like head-up displays, adaptive cruise control, and comprehensive onboard computer systems. Special market specifications, such as German TÜV, French CO2 tax compliance, or eligibility for historic registration, may be relevant depending on country.
