The Avant arrived in mid 2001.
For 2002, Audi upgraded power in the 1.8 Turbo engines to 163 PS (120 kW; 161 bhp) and 190 PS (140 kW; 187 bhp) – the 190 PS variant designated by a red 'T' on the boot lid, with both available with quattro, and in the 2.5 TDI intermediate version to 163 PS (120 kW; 161 bhp). A 2.0 engine with Fuel Stratified Injection (FSI) was also available. A year later, Audi reintroduced the S4, now powered by a 344 PS (253 kW; 339 bhp) 4.2 L V8 engine, as well as an A4 Cabriolet convertible variant (Typ 8H), finally replacing the 80-based Audi Cabriolet which had been discontinued in 1998. It included an electro-hydraulic operated roof, which lowered in under 30 seconds, and incorporated some styling changes which eventually found their way to the saloon version (such as body-coloured lower bumper and sill panels).
Audi also introduced a continuously variable transmission developed by LuK, named multitronic, which replaced the dated conventional automatic transmission on front-wheel drive models. The transmission won considerable praise from the automotive press, and is generally regarded as being the best of its type in the world, due to its light weight and promptness in response. This high strength chain driven CVT is made from highly durable metals and utilises a very high grade, purpose-designed fully synthetic lubricant. However there have been widespread complaints from consumers around the world that the transmission box is prone to electronic glitches as well as mechanical problems.
Borrowing from the Audi A6, the boot was redesigned to remove the extension of the top edge with a smoother fold line, and the rear light assemblies now formed part of the top line, these styling cues were eventually borrowed by other European as well as Asian manufacturers.
The basic equipment that is standard across all versions of the Audi A4 Saloon (00-04).
An "ultra sport package" named 'Ultra Sport' was introduced in the North American market shortly before the B6 was replaced by the B7. It included aluminium interior trim and door sills, "S line" steering wheel, front and rear spoilers, side skirts, and quattro GmbH designed 18-inch RS4 alloy roadwheels.
