I don't think that concept version ever made it to production, at least not at that power.

This did though, and it's only 303hp. Further, it's all shit that came standard on the MR, for the most part. Regardless, the X is heavier than the IX/VIII and the motor isn't nearly as bulletproof as the 4G63.
I love turbo 4 bangers but Subaru and Mitsubishi literally killed their own product by making politically correct cars.
EDIT: US Final Edition is rated at 291hp, LOL.
