The first-generation Audi A4 was introduced into the market as a four-door saloon/sedan during 1994, which was built on Volkswagen’s B5 (PL45) automotive platform. Featuring the infamous Quattro four-wheel drive system, the initial version of the Audi A4 could deliver enough power punch with the 2.8 liter 12-valve V6 engine, to impress its potential customers.
In the subsequent year, Audi Avant, a wagon form of A4 was introduced into the market.
B5 facelift (1998–2001)
The Audi A4 got its first facelift during 1997, including brand new headlights, door handles, rear lights, and minor cosmetic changes. However, it wasn’t just about the facial facelift, as the A4 also received a 2.5 litre V6 Turbocharged Direct Injection (TDI) diesel engine that could deliver 148bhp, while the 2.8 litre 12-valve V6 was upgraded to 2.8 litre 30-valve V6 engine.
