Interesting concept, yet I believe this will not yield high sales. The only niche this car will appeal to is people in the market for miata's, s2k's or cars of the like. Even then, although maybe biased with my prior Honda background, I would take the higher revving, higher horsepower yielding s2k over the "BRZ."
I believe that Subaru and Toyota, may have missed the mark on this car as the loyal Subaru buyers in the sports car market. (Those whom have purchased wrx/ sti models) Will consider this car a underpowered waste of time. Heck, if I wanted a RWD car with ~200hp I would get myself an s13 and do a sr20 swap or boost the KA, or a 370z.
Mini coopers and Miata's handle like they are on rails but the majority of this community would not think about purchasing them. The Advanced AWD system coupled with the bliss of having F/I are what lure many into buying a wrx/sti.
As someone stated prior, this car will most likely have similar success as the rx-8. Meaning that, it almost lost its, "Subaru Mojo." The attractiveness of the Subaru brand has been smudged by Toyota counterparts. The rx-7 was an very attractive, high performance vehicle and when the rx-8 came out, many were disappointed with the castrated rx-8 that essentially replaced the beloved rx-7.
To each his own car is sharp and probably handles well, but I will never buy one. Hopefully an "STI" model comes out to bump its horsepower and after-market support to lure in additional buyers.
