Available in Sedan, Convertible and Station Wagon flavors, the Audi A4 is at home trekking to work, soccer practice or the beach. The popular A4 accounts for over half of all Audis sold today. Introduced in 1995 as an upscale version of the VW Passat, the A4 put Audi on the map as a luxury car manufacturer.
The A4 has been built in four generations and is based on Volkswagen's B platform. The first generation A4 succeeded the Audi 80. The automaker's internal numbering treats the A4 as a continuation of the Audi 80 lineage, with the initial A4 designated as the B5-series, followed by the B6, B7, and the current B8. The B8 A4 is built on the Volkswagen Group MLB platform shared with many other Audi models and potentially one Porsche model within Volkswagen Group.
The Audi A4 automobile layout consists of a longitudinally oriented engine at the front, with transaxle-type transmissions mounted at the rear of the engine. The cars are front-wheel drive, or on some models, "quattro" all-wheel drive.
