Well this makes sense and I'm glad they acknowledged the mistake they made while transitioning to turbo. Displacement made sense in NA era since the actual size of the engine translated into power but with turbo you either put horsepower on the badge or you just name the tiers in the lineup. 300 for midrange and 500 for high end models. There should never be IS/RC/ES500, that exclusive 500 badge most likely will be reserved for LS/LC/upcoming FSSUV and perhaps repositioned GS. Even if IS/RC come up with turbo V6 they should still be named 350 or 400
