Aftermarket tuner Hennessey Performance Engineering has added more power to Ford's ferocious F-150 Raptor pickup with the Hennessey Velociraptor 500, and now Top Gear USA has had a chance to test it, with the Stig behind the wheel.
The truck has a 501-horsepower supercharged 5.4-liter V-8, high-flow air induction, stainless steel headers and catback exhaust, and special exterior and interior badging.
There's also a one-year/12,000-mile limited warranty.
Hennessey claims the truck can run 0-60 in 5.6 seconds and hit the quarter-mile in 14.1 seconds.
Take a gander at the video below to see the Stig putting this amped-up truck through its paces.
