2001 audi s4 for sale 1
Fast Facts:

  • The S4’s 2.7L V6 has smaller bores than the A4’s 2.8L V6. This is due to the S4’s increased cylinder wall thickness to handle turbo boost
  • Max torque (258 lb ft) is available from 1850 rpm to 4000 rpm, and is a completely flat torque curve. Audi offers the same engine in the A6 2.7T
  • The Bi-Turbo DOHC V6 has 5 valves per cylinder (total 30 valves). It utilizes a cast iron block, forged steel crank, and a variable geometry composite intake manifold. Magazines claim 350 hp is a simple chip and exhaust system upgrade away, although this will shorten the life of the factory turbos
  • Features two parallel water-cooled BorgWarner K03 series turbochargers peaking at 11 psi of boost. Two side mounted air-to-air intercoolers cool the incoming charged air
  • The 6spd manual gearbox doesn’t have a 1:1 direct drive, unlike the automatic trans (4th gear). In the manual gearbox, 3rd gear is 1.231:1, 4th gear is 0.967:1, 5th is 0.806:1, and 6th is 0.684:1. The axle ratio is a steep 4.111:1, allowing for frequent shifts under highway speeds
  • The control arms feature Audi’s patented hydraulically damped pivot bearings
Key Model Year Changes:

  • The B5 S4 was produced between 2000 and 2002
  • 2001 models differences include aluminum mirrors on the sport package, ESP (traction control), and upgraded tires. The Avant became available as well
  • The significant changes occurred with the 2001.5 models (This particular car appears to be 2001.5 because the badge has one solid stripe, as opposed to 2 stripes on the older cars. But this isn’t always the case. Build date needs to be verified with seller)
  • The 2001.5 S4’s feature larger oil inlet lines to the turbo (increasing lubrication and improving reliability), revised throttle body boot, and the problematic F shaped hose is no longer used
