14. Subaru XT
Introduced in 1985, the Subaru XT was a two-door coupe that showcased a distinctive wedge design and innovative features, including a digital dashboard and adjustable pneumatic suspension. Despite these technological advancements, the XT struggled to establish itself in the luxury market. Its performance was adequate, but the interior trim and ergonomics did not meet the expectations of luxury consumers, leading to limited success and its eventual discontinuation in 1991.
