1994 Audi S4

As the E34 M5 and W124 500E/E500 creep up in value, if you search you can still find excellent examples of the odd-ball turbocharged inline-5 all-wheel drive wonder from Ingolstadt. While both of those cars are legends and fan favorites in their own right, I’d like to suggest that most underappreciated yet most capable of that generation was the C4 Audi S4. Out of the box, it was at a disadvantage to the other two; it’s small displacement cast-iron inline-5 hung fully in front of the forward axle line and was at a distinct power disadvantage. With 227 horsepower on tap, it was some 84 horsepower shy of the S38B36 and nearly a hundred down on the M119. But it was turbocharged, so torque was over 250 lb.ft – close to the BMW’s level. Still, they were fairly heavy and if you wanted to shuffle with the Municher and Stuttgarter, you had to keep that AAN on boil and on boost. But the trump card that Audi presented in the market at that point was all-wheel drive, and coupled with the tunable nature of the AAN, it meant there was a lot of potential in the chassis of the C4. That was met with excellent build quality to create what was perhaps the zenith of Audi’s production in the inline-5. Despite that, they have remained far more affordable than either of the competition, though finding a good one today can be difficult. One of just 399 ’94s sold in the U.S., this Brilliant Black example is one of 50 sold with black leather:

2001 Audi S4 Avant

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’s model years, with about 600 of those being Tiptronic equipped. LY9B Brilliant Black was the second most popular color ordered behind Light Silver Metallic, and this particular Avant is one of 183 Brilliant Black (out of 850 total) manuals brought in for the 2001 model year:
