Overlooked in its time and underappreciated even now, the Audi V-8 was the brainchild of legendary overengineer Ferdinand Piëch, who spearheaded the original Audi Quattro. It looked like any other Audi but packed every modern amenity and ran a brand-new all-aluminum quad-cam V-8. It also used some clever engineering to marry an automatic transmission to the company’s famous but brusque all-wheel drive system. Though it wasn’t a sales hit, the Audi V-8 found great success in racing, winning the DTM title back-to-back in 1990 and 1991. It presaged the modern luxury car: packed with tech and without compromise in power or drivability. — Raphael Orlove
