Audi brought the S4 Avant to the United States for the first time in 2001. It joined the sedan lineup and offered a follow-up to the large chassis S6 Avant from 1995. This was actually the second S4 Avant, as Europeans had enjoyed the C4-based creation in the early 90s. Audi’s renaming convention therefore created a successor to the B4-based S2 Avant. Instead of the traditional inline-5 motivation, though, Audi had developed a new 2.7 liter version of its V6. With a K03 turbocharger strapped to each side, the APB produced 250 horsepower at 5800 rpms and 258 lb.ft of torque at only 1850 revs. Like all the B5s, Audi’s new generation of quattro used a T2 Torsen center differential and relied upon an electronic rear differential utilizing the ABS sensors. The B5 chassis used the same technology on the front differential as well and was capable of independently braking each front wheel to try to sort the car out through its dynamic stability program.
But the real fun was that it was available as an Avant and with a 6-speed manual. Just over 1,500 were claimed imported between 2001 and 2002 model years, with about 600 of those being Tiptronic equipped. This is one of a claimed 80 Imola Yellow 6-speed manual Avants imported for the model year, and for good measure it’s got quite a few upgrades:
The B8 A4 Avant is a pretty good looking car; but here in the US we were only offered the chassis in one figuration; the 2.0T quattro hooked to an automatic. Even when the “Allroad” returned to the lineup, it was really only an appearance package on the standard A4 with taller springs and larger sidewall tires. Considering the plethora of options that had been available on prior Audi wagons, it was an understandable disappointment.
Inspired by this, enthusiasts have sought to remedy the problem by combining the Avant’s platform with its sibling powertrain; this feels like ‘throwback’ tuning at its best! So here we have an ’09 A4 Avant that’s running the gear from a S4. Sweet! The thing is, it’s not quite complete…
To me, if you’re going to go through the effort to get into a B6 and pay a lot of money as you would with the 2004 A4 3.0 quattro Avant Ultrasport I just looked at, why would you not consider the S4 Avant? Not only is it a lot more powerful, you could get them in splashy colors, and with a 6-speed manual to boot. Add in better seats, better looking wheels, and…well, better stuff, there’s only one real reason to not consider the S4 over the A4 – and that’s the engine’s incomprehensible chain system.
But let’s say that the chain repair upgrade was already done, for argument’s sake…
The Audi S4, now in its 7th iteration, has been a perennial performance favorite of those who like the understated looks coupled with all-weather performance. And since the original, the S4 has offered a unique tuning platform; while the B6 and B7 were difficult to extract extra performance out of, the other generations have offered forced induction out of the box that allows for generous tuning potential for a real sleeper supercar slayer. 1,000 horsepower isn’t unheard of out of the legendary inline-5, but power numbers exceeding 400 seem to be almost commonplace for the C4 and B5 S4s. So when Audi launched the supercharged V6 model in 2009, the return to a smaller displacement forced induction powerplant immediately had me thinking that it wouldn’t be long until tuned versions appeared. The trick in buying a S4, though, is and always has been managing to find an unmodified one that is well cared for but also affordable. After all, for under $10,000 you can run out and grab any one of the first three generations – however, the less you spend up front, the more likely you’ll be dishing out of pocket in the future it seems. But as we get towards the newer generation of B8 you can get a car that is still quite new for a substantial discount over the original purchase price without (generally) the fears of abuse, neglect and immediate repairs that need to be undertaken. Today’s example has the right ingredients; mileage is in check, it’s a manual, and it’s a neat color. But is it the right one to get?
In just a few years, Audi went from only one S model with very limited production imported in the C4 S6 to three models. Top of the range was the S8, but it shared its running gear and sonorous V8 in a slightly detuned state with the new C5 S6. For Audi enthusiasts, though, big news came with the launch of the new S4.
It was unrelated to the first S4 because of Audi’s renaming strategy in 1995. That meant that the new S4 was based on the small chassis B5, and U.S. enthusiasts finally got a taste of Audi’s M3 competitor. Performance came in the form of a new 2.7 twin-turbocharged V6 30V and was mated to either a 5-speed Tiptronic transmission like its bigger siblings or a 6-speed manual. Like other B5s, the S4 made use of the 4th generation of quattro technology driving all four wheels. This utilized a Torsen center differential with open front and rear differentials, both of which employed the ABS sensors to electronically ‘lock up’ the slipping wheels when a speed differentiation was detected. Like other S models, some light revisions to the bodywork and more pronounced exhaust were present, along with polished mirrors and 17″ Avus-design wheels. Most notable was the large front bumper cover with 6 gaping grill covers which hid the twin intercoolers for the motor. With 250 horsepower and 295 lb.ft of torque, you had an all-weather 155 mph warrior. And, it was available as an Avant:
