Itâ€™s often difficult for a second act to follow a legend, and thatâ€™s just what the C4 S4 had to do when it launched for U.S. customers in 1992. The Type 44 was already a fan favorite before the 20V version appeared here briefly for the 1991 model year, with wider flared track, bigger brakes, and more power. To answer fans, Audi introduced an even more potent version with the S4; even bigger wheels, lower suspension, and a few more horses were encased in a thoroughly modern shape, yet one that was easily recognizable to fans of the brand. With a reputation for smooth power delivery and still the market cornered on all-wheel drive performance luxury vehicles, Audiâ€™s new S4 sold out almost immediately in a period when the European makes had difficulty moving their expensive wares.
But the Type 44 still held one advantage over its replacement; as we saw recently, an optional fifth door. While the Avant version of the new 100 was available immediately, there was no range-topping S4 wagon brought here. That was finally remedied with the relaunch of the now renamed S6 Avant for 1995. With smoothed out bumpers, revised passenger mirror, rolling changes such as new Speedline Avus 6-spoke wheels replaced the Fuchs that the S4 wore, and headrests became closed. There were more changes with the â€˜95.5â€™ model; the infrared remote locking became radio frequency and the B-pillar receiver disappeared; so, too, did the option to lock the rear differential yourself, as Audi opted to work in an electronic differential lock utilizing the ABS speed sensors rather than a physically locking rear end.
These were really only minor changes to the recipe, which at its roots remained a fan fantasy. The traditional inline-5 that had hung out of the nose of the high-end Audis was still there, with its dual-cam head augmented by electronic fuel injection and electronic boost control. The turbo spun up quickly and had an overboost function, giving drivers 227 horsepower and 258 lb.ft of torque to be mastered solely by a manual transmission with Torsen center differential. Form-fitting electric sport seats kept front passengers firmly planted in place through the prodigious grip generated by the meaty 225 section tires. Combined with the prodigious space the Avant offered families and the ability of these cars to eat up highway miles with aplomb regardless of weather, not to mention the incredible tuning potential of the AAN 20V turbo, theyâ€™ve become highly sought steeds with a very limited pool of around 300 originally imported:
