TopGear recently reached out to Texas-based Hennessey Performance to put their customized Ford F-150 Raptor to the test, dubbed the VelociRaptor 600.

In this clip, we get a behind the scenes look at the company building out the tuned truck, which features upgrades like a 2.9 Liter Supercharger System and an air-to-water intercooler. Design touches include Hennessey and VelociRaptor exterior badging, Hennessey-embroidered headrests, and more.

Just 500 units of the Velociraptor 600 will be produced, with prices starting at $73,000 USD including the vehicle, or $23,900 USD if you bring your own.
