Background and Identification
Produced by German car manufacturer Audi, a subsidiary of the Volkswagen Group, the Audi A4 is a line of compact executive cars. Since its creation in 1994, the Audi A4 has seen five generations and is based on the Volkswagen Group B platform, a mid-size car platform. The A4 came in succession to the Audi 80 and according to the brands’s internal numbering system, the A4 is a continuation of the Audi 80.
The A4’s automobile layout consists of a front-engine design, with a transaxle-type transmission mounted at the rear of the engine. Furthermore, the cars are front-wheel drive or “quattro” (Audi sub-brand to indicate all-wheel drive).
