Audi RS4 I (B5) gallery (2000–2001)
The original RS4 — a B5-based super-wagon with a Cosworth-developed biturbo V6.
The B5 RS4 Avant (2000–2001) launched the RS4 nameplate and became one of Audi's most iconic wagons. Its 2.7-litre biturbo V6, reworked by Cosworth, made 380 hp, driving all four wheels through quattro.
Built in limited numbers, the B5 RS4 is now a sought-after collectible. Its blend of understated looks and extreme performance defined the RS4 philosophy for decades.
