It still hasn't really sunk in yet--it probably won't until our right foot goes to the floor--but the 2013 Ford Mustang Shelby GT500 packs 650 horsepower. Six hundred and fifty. That's not just insane, it's totally crazy.

That's 50 more horsepower than the Dodge Viper, a car known for being so powerful and raw that it's essentially murder distilled into four-wheeled form. Of course, the 2013 Shelby GT500 is more refined in many ways, including standard traction and stability control (both of which the Viper lacked entirely), but still. That's a lot of power for a street car. A lot.

We're not complaining. We're just in pony-induced shock.
