For such a relatively short-lived and obscure model in the U.S. market, the 90 model sure went through a substantial amount of changes. It makes nearly every model year unique in some way, and so few come to market they’re always neat to see regardless of the generation. The 90 replaced the 4000 for the 1988 model year with the upgraded Torsen-based quattro, the new B3 body and interior and the updated 2.3 NG 10V motor for the 88-89 model year, and was sold alongside the technically identical but less upscale 80 model for the same time. 1990 saw the introduction of the short-lived double-overhead cam 7A motor and some other minor changes, but scant numbers were brought over. Technically, there’s no ’92 90, but there are still some floating out there because…well, Audi. Then officially in ’93, the “B4” chassis arrived, with revised rear suspension, body bits and a new 2.8 liter V6. Even then, for the ’93-’95 B4 quattros, each model year was a bit different – surprising, given their very limited numbers. Available only in “CS” upscale trim, the 1993 90CS quattro, 1994 90CS quattro sport and 1995 Sport 90 quattro only combined for 2,855 examples. They’re pretty hard to find, though admittedly there are even fewer ’90-91 20Vs or ’92 80 quattros floating around.
Most of these cars were upscale and featured either the Speedline-made 10-spoke 15″ wheels or the later Ronal-made Votex 5-spoke design. A raised spoiler and limited badging were hallmarks of the later ’94-’95 sport models. Though generally not as desirable as the ’95 Sport model, the ’94 is more rare and just about identical to the ’95 model. So, when they arrive in near perfect condition with under 100,000 miles, the bids start rolling in for the devoted fans who love them:
