The 1989-1991 Audi 100/200 was a mid-size executive car produced by the German automaker Audi. This generation, known internally as the C3, represented a significant evolution for the Audi 100, introducing a new platform, styling, and technology. The 100 and 200 models were essentially identical in terms of mechanics and chassis, but differed in their trim levels and equipment. The 100 was the standard model, while the 200 offered a more luxurious and feature-rich package. The C3 generation was designed to be lighter and more aerodynamic than its predecessor, featuring a smooth, rounded body style with a drag coefficient of just 0.29. This aerodynamic efficiency contributed to better fuel economy and reduced wind noise.

The Audi 100/200 boasted a range of powerful and efficient engines, including a 2.0-liter four-cylinder, a 2.3-liter five-cylinder, and a 2.8-liter V6. All engines were paired with a five-speed manual or a four-speed automatic transmission. A highlight of the C3 generation was the introduction of Audi's revolutionary quattro all-wheel drive system, which offered exceptional handling and traction in all weather conditions. The quattro system was available on select models and marked a significant step forward in automotive technology. Inside, the Audi 100/200 offered a spacious and luxurious cabin with a high level of comfort and refinement. The interior featured high-quality materials, well-designed ergonomics, and an array of advanced features, including power windows, power mirrors, and air conditioning. The 1989-1991 Audi 100/200 was praised for its performance, handling, and comfort, solidifying its reputation as a formidable player in the mid-size luxury car segment.
