I've never heard even the slightest of rumor of a Fusion ST. I've seen wishful thinking posts, but in general, given the size of the car, they'd never cram the 3.5L EB motor in there with all that's required, so it'd be nothing more than a Mustang EB in a different body if they put anything larger EB wise. Sorta. Anyhow, I don't see Ford looking to invest big money in a new vehicle variant that's going to hurt a variant in another line, especially an iconic one like Mustang. I just don't see it. Sure, there's the Focus ST and the Focus RS coming, but that's a totally different type of car. Now, if for some strange reason they killed the SHO in favor of a Fusion ST, then ...well... then that would suck. <Sigh> lol
