The Audi A4 (1997) is a compact executive car that marked a significant shift in Audi's design language and engineering prowess. It was the first generation of the A4 series, designated as the 8D platform, and was introduced as a replacement for the Audi 80. The A4 8D was available in a variety of body styles, including a saloon (sedan), an estate (wagon), and a cabriolet (convertible). It was renowned for its sleek and modern design, featuring sharp lines, a spacious interior, and a focus on driver-centric ergonomics.

The platform spawned several performance-oriented variants that cemented the A4's reputation as a sporty and sophisticated car. The S4, powered by a 2.7-liter twin-turbocharged V6 engine, offered exhilarating performance while maintaining a level of luxury and practicality. The RS4 Avant, introduced in 1999, took things even further with a high-revving 2.7-liter twin-turbocharged V6 engine producing a staggering 380 horsepower, making it one of the quickest station wagons of its time. The Allroad, a raised station wagon with permanent all-wheel drive, further expanded the A4's appeal by offering increased versatility and off-road capability. The A4 8D was a major success for Audi, solidifying its position as a leading brand in the premium compact car segment. Its combination of stylish design, advanced engineering, and performance options set the stage for future generations of the A4 and established it as a benchmark for the segment.
