The XT was Subaru's first attempt at producing a sports car. They launched this arrow shaped 4 wheel drive beast in 1985. The most notable thing about the XT was that it broke the record for air resistance with a .29 coefficient of drag. This record may still be standing today, (I can't find any records of it being broken).
The XT featured 4 wheel drive, (later changed to all wheel drive), 4 wheel independent adjustable suspension, (this used airbags like big diesel trucks have), and a turbocharger. The XT was eventually replaced by the Subaru SVX. But the SVX was in a different class. The XT was a Camaro fighter. While the SVX competed on Corvette level in the automotive arena.
