This is just Toyota's new management trying to bring back a little fire to their line. Don't think it's going to work though. The only reason they are using the boxer motor is so they can get the low sloping lines they want in the front end. The boxer motor allows for that low hood slope. As for teaming up with Subaru, if they already have a viable motor there is no reason to reinvent/retool a factory to produce one. This car is designed to compete directly with cars like the Genesis but I think it is a little to late.
I'll keep driving my 15 yo Toyota and like it.
