The new Ford Shelby Mustang GT500 weighs in at a whopping 4,225 lbs.

Typically, high-performance sports cars aim for lightness in their construction. There are several reasons why you’d want a car to be as light as possible, but overall speed is the first that comes to mind. The lighter the car, the easier it is to make it move quickly.

So it comes as some surprise that the new Shelby Mustang GT500 is quite the girthy automobile.

Mustang enthusiast site Mustang6g Forum managed to acquire a copy of Ford’s eSourceBook for the GT500. This digital book is designed to provide dealers with as much information as possible in order to answer potential customer questions. It doesn’t have everything--we still don’t have a 0-60 mph time, for example--but the book does have several important stats.

One of those is the car’s weight. At 4,225 lbs, the GT500 is the heftiest it has ever been--350 lbs heavier than the previous generation’s GT500, and 420 lbs heavier than the current-gen GT350. It’s only a few dozen pounds lighter than a Dodge Challenger SRT Demon.

On the plus side, the Carbon Fiber Track Pack should cut down on the weight somewhat (although the book doesn’t say precisely how many pounds are shed) thanks to increased use of carbon fiber in the body, carbon fiber wheels, and an optional rear-seat delete. The GT500 also has a 56:44 weight distribution, which should allow for some decent handling.

The all-new Shelby GT500???the pinnacle of any pony car ever engineered by Ford Performance???delivers on its heritage with more than 700 horsepower for the quickest street-legal acceleration and most high-performance technology to date ever offered in a Ford Mustang.

We also found out that the GT500's 760 horsepower doesn't arrive until the very ragged edge of the engine's rev range at 7,300 rpm. Peak torque arrives at 5,000 rpm, however, with 90% of that torque available starting at 3,450. Still, getting maximum power out of the 5.2-L supercharged V8 will require shifts almost directly at the car’s redline.

There’s an enormous list of features available in the 86-page document, which you can check out for yourself here. We’re sure to learn more from Ford as they squeeze out the car’s details over the coming months.
