So I have a 2004 a4 and I thought it was the sline. Till someone told me it was the ultrasport. What is the difference between the two? I have six gears, carbon fiber trim, its lowered and has 18" wheels, the shark fin antenna, the deck lid spoiler. Oh yeah the body kit is painted the same color of the car.

 

Here's the best description I could find about the Ultra Sport:

"sport suspension, front and rear bumpers, door sills, trunk spoiler, aluminium trim, poked leather steering wheel and shift ****, and they only had Ebony Black interiors."

I've also seen talk about a lip on the front lower fascia, and a perforated steering wheel.

If you have all that, you probably have an All Sport. Of course, you could probably find out from the dealer by giving them your VIN.

 

Here is a link that should help you.
