I'm sure this been discussed before, but a search came up dry.
I'm curious for more details as to what specific components and systems were engineered by Toyota and what was done by Subaru.
My general understanding is that Subaru builds the twins and engineered most of the mechanical systems and chassis, while Toyota covered the styling, interior, and electronics. So is fair to say that the car is mostly a Subaru product?
Now that the cars are designed and in production is there any more joint engineering going on? Or will both companies develop further innovations to the line independently?
