Rare Rides: An Almost New Audi S8 From 2001 (Part I) Rare Rides has featured the predecessor of today’s sedan previously, in a very pearly 1990 V8 Quattro. After Audi spent a few years unsuccessfully trying to sell its first-ever attempt at a flagship full-size sedan, it took the lessons learned from the D1 and developed the D2 A8 and S8. Today we’ll focus primarily on the A8 foundations that made the S8 possible. Work on the D2 platform began in 1982 when Ferdinand Piech signed a development contract with Aluminum Company of America (you’d probably call it Alcoa). The goal of the agreement was the use of aluminum technology to design a sedan that was lighter than other cars of a similar size class.
