Want to know what a 563-rear-wheel-horsepower 2012 Ford Mustang Boss 302 looks like? Here's your answer.

Devised by the evil geniuses at Hennessey Performance Engineering, the HPE650 supercharged Mustang Boss 302 is estimated at about 650 crank horsepower, hence its name.

As you can see from the video, the Hennessey grew don't look to have gotten much past the engine tuning stage on the new 2012 Boss yet, but we expect they'll do their typical full treatment, including suspension, body, wheels and paint, before they're finished.
