Ten years ago Audi celebrated their 25 years of Quattro by giving the United States (Sorry Canada, the bumpers didn’t meet Canadian low-speed crash test standards) a special delivery of 250 B7 S4 special ‘25quattro’ editions. All painted in a typically German Avus Silver color, these cars got DTM inspired front and rear bumpers that wear non-functional brake ducting and finished off with an aero-style lower rear valance (with a red tow hook hiding below it) and a carbon fiber trunk spoiler with matching front splitter. The wheels are again DTM inspired with a 15 spoke design pattered after OZ Racing but ironically made by long Audi supplier Ronal. On the inside, your typical full Recaro setup is there with two-tone seats in jet-gray as well as some carbon fiber trim and ‘1 of 250’ shift knob. All said and done, Audi gave it’s fans a nice cosmetic package to different from the rest of the B7 S4s. Unfortunately, the 25quattro received no performance upgrades outside of some different exhaust tips to give you a slightly more aggressive sound, but the car did receive the revised more rearward biased drive system also found in the RS4. Being only 1 of 250, this 25quattro located in California might fulfill your appetite for a rare V8 Audi without stepping into RS4 territory.
