About AUDI A4
The Audi A4 is a luxury passenger car (D-segment in Europe) by the German brand Audi within the Volkswagen Group. It is the successor to the Audi 80 and began its production in 1995.
The Audi A4 has a total of 5 generations, and has been marketed in multiple body styles. The Sedan and Estate bodies are present in all generations, while other variants such as the Audi A4 Coupé or Cabrio ended up being exclusive Audi A5 versions from 2008 on.
The first-generation Audi A4 (8D) was built on the Volkswagen Group B5 (PL45) platform, shared with the Volkswagen Passat. This A4 had Sedan and Avant (Wagon) versions. It was a longitudinal front-engine vehicle with front-wheel or four-wheel drive using Quattro technology. This first generation was marked by Audi’s advances, as this model was the first to debut the Tiptronic automatic gearbox and the 1.8 20-valve engine, which Audi had originally designed for competition. In 1999, the A4 was redesigned, improving the general lines of the vehicle and adding the Audi S4 performance variant and the ‘Racing Sport’ model, i.e. the Audi RS4 Avant, based on the previous RS2.
The second generation would arrive in 2000, based on the Volkswagen Group B6 (PL46) platform. This A4 Gen 2 followed the ‘Bauhaus’ design initiated in the Audi A6 C5. Almost all models of this new generation received power or displacement engines. The 1.9 TDI models also saw a boost to 130 hp. In addition to the performance versions, this generation also had a Cabriolet version.
The third generation debuted in 2004, with one of the most attractive models of the entire line thanks to Walter de Silva’s design. However, it was originally a redesign of the previous model, only with a very aesthetic approach. This third generation received the FSI engines (stratified fuel injection), and 2.0 TDI engines. In 2008, VAG reused this design to launch the Seat Exeo, a model identical to this A4 B7, but sold as Seat. The Cabriolet model of this generation remained, albeit with very few changes.
The Audi A4 B8 was introduced in 2008, based on the VAG MLB platform. This generation would finally separate the Sedan versions from the Coupe and Cabriolet with the release of the Audi A5. This model had several redesigns during its life, and is the longest generation of A4 to date.
Finally, the current model of the Audi A4 is the fifth generation, the B9. It is produced on the MLB Evo platform, shared with several of Audi’s D-segment and above models and the Porsche Macan.
The alternatives to the Audi A4 have always been the German sedans, i.e. vehicles such as the BMW 3 Series or the Mercedes-Benz C-Class and their Estate / Wagon versions.
