I'm an oddball, but I wish they made their vehicles available with just front wheel drive. Why do they ignore this part of the market?
Basically, Subaru adopted all-wheel-drive as a standard feature to differentiate themselves from the competition. In the 1990s the company was doing poorly in the U.S. and they even considered pulling out. (Although Subaru had offered 4WD since the early 1970s it was an optional, manually-operated, part-time system not available on all models.)
It used to be that one of Subaru's biggest selling points was front drive, which in their early days here was an unusual, almost exotic feature. However by the 1990s it was just "me too". Having standard all-wheel-drive across the board gave them a feature the others in their class didn't have. It proved to be a very successful strategy so they have stuck with it, the BRZ excepted.
