Well with a Lancer GTS starting below $22k, even after adding some fancy bits, a turbo and AWD for the Ralliart, it ought to come in at what, maybe $32k (and undercut the WRX by a few g's, like Carcrazy said)? That would make for a very reasonable $8k jump to the EvoX, no?
I think looking at the pricing structure and product line up these prices make a bit more sense. Of course, Subaru doesn't see it that way with more than double the cost of a basic Impreza to a top line STI model, so who knows.
