Newly formed Saleen Performance Vehicles released their first 2010-based Mustang, the 435S, this past summer, but the lack of any significant design upgrades left us wanting something a little more. We knew an S281 model was soon to follow, and thanks to Saleen's Flickr page, we now know the car will make its debut at the SEMA show in Las Vegas. The three photos posted on the site actually provide a decent look at the front and rear of the car, and we especially like what's been done to the 2010 Stang's controversial rear with the elongated tail and the diffuser-style rear valence. Check back for full details and plenty of photos when we cover the 2010 Saleen S281 Mustang's live unveiling early next month.
