to an extent? i guess you're one of those people that believe that subaru developed the whole car while toyota merely styled it, and took all the credit...
lets examine some facts:
-the engine uses D-4S, a toyota system.
-the car is code named FT86 which harks back to the AE86
-the car will use Yamaha tuning, another company that toyota has a stake in, and that is indicative of toyota involvement
-the engine is a "NEW" engine. its not an off the shelf subaru engine. in other words, its based on a subaru engine, probably the FB, but it had to be "improved" for use in this car.
-its RWD, a toyota AE86 trait, not a subaru trait
-manual AND automatic tranny is rumored to be Aisin, another company part owned by toyota. subaru uses JATCO automatics and CVTs, not Aisin automatics
the list goes on. faced with those facts, who can honestly say subaru developed the car themselves? and im talking specifically about the engine/drivetrain. it was a joint effort but imo we all get the feeling it's much more of a toyota project with subaru help, than a subaru project with toyota help.
imo people who fail to see this just arent looking at it objectively...
