B7 (2006 to 2008)

The Audi RS4 B7 (2006–2008) remains a high-water mark for the brand, famously being the only generation to feature a high-revving, naturally aspirated 4.2L V8 paired exclusively with a 6-speed manual transmission and a rear-biased Quattro system. In the 2026 Australian market, the B7 is highly desirable as a "pure" mechanical investment, attracting a loyal buyer pool of purists who value its 8,250rpm redline and visceral hydraulic steering over the turbocharged, automatic models that followed. Available in Avant, Saloon, and Cabriolet body styles, its desirability is further bolstered by its shared DNA with the original Audi R8 engine and its "sleeper" status. Current Australian market values are steadily climbing, with well-maintained examples typically fetching between $65,000 and $95,000 AUD, while "collector-grade" units—especially Avants with the optional RS wingback seats and low mileage—can exceed $115,000 AUD at specialist auctions.
