The 2013 Ford Mustang Shelby GT500 was unveiled at the 2011 Los Angeles Auto Show last month, and we were there to cover it. What isn't widely known, however, is that the car on the show floor didn't have the new 5.8-liter, 650-horsepower engine under the hood. It still had the previous 5.4-liter version. This image shows what the new engine will look like.
As you might expect, it looks a whole lot like the current one--the main differences are on the inside. A new TVS series 2300 supercharger displacing 2.3 liters sits atop it, however, helping the big V-8 reach its phenomenal production car power figure by flowing more air than the previous 550-horsepower 5.4-liter's supercharger.
