A fourth generation VW/Audi chassis that makes the basis for the 1999-2005 Jetta, Golf, and Beetle; also, makes the basis for the Audi TT and first generation Audi A3/S3. A4 is the chassis code for the fourth generation of the "A" type of VWAG's cars.

Usually used among VW fans to differentiate different generations of the Golf and Jetta. A4's were thought of as pretty cool to the masses, but VW fanboys who can't afford them decry them for being too heavy, even though they were faster than previous generation VW's.

This can be really confusing; the Audi A4 is built on a B5 chassis (the same as the 1998-2005 Passat).

Also referred to as a Mk4.
"I had an A3 Jetta but traded it for an A4 GTI."

"He had an A4 GTI and I was like 'how do you like that A4?' and he was like 'uh, I have a GTI, not an Audi' and I was liek OMG WTF u r lyke SUCH A RETARD you don't even know wot a A4 is???? hahahahaha I'm so l33t"

an audi a4 is not a drunkin fin car....i dont know what that ee\ven means, anyways. the a4 is a truely impressive car, not only for spectators (ok, so some body styles arent that good looking) but for the driver. even the oldest inspiratio ns for the a4 are truely magnificent cars. they drive, handle, and are styled beautifully. i prefer the a4 to many BMWs and especialy most mercedes. while, yes, the car is expensive to fix, you dont need to fix it that often, but for the car, a simple, large check is a smal sacrifice for such a driving experience.
its an EASY car to speed in. drives like a dream and it is fast.... al the body styles are fast and well engineered. audi a4 is a great car
