The first teaser image from Roush for their upcoming program for the 2015 Ford Mustang has been revealed. Although they had nothing to say about the new car other than the #ROUSH550 hashtag we can see the car will be fitted with a ventilated hood, larger rear spoiler, five-spoke alloys and some fender badging. I am taking a guess that the 550 in the hashtag is referring to the number of ponies this thing will put out.
