The WRX STI is definitely getting long-in-the-tooth these days, it hasn't made any significant improvements in the 300-HP 2.5L engine that's been powering it now for the last 10 years. 10 years ago, it was technological marvel, now it's out of date. The regular WRX's 2L turbo is newer, much more efficient, but only slightly less powerful. If they tweak up that existing turbo-2L and that can become the new STI. It might still be too late as the Ford Focus RS is going to have a 350-HP
4-cylinder. So it'll be down by about 25-HP.
