If you haven’t already watched Ken Block’s Gymkhana 7 video -- stop, watch it here. For those who’ve seen the ridiculous awesomeness that is the all-wheel-drive, 1965 Ford Mustang Hoonicorn, here is another video that dives deep into the inner workings of this tire-shredding beast as Chris Harris takes us on a grand tour of the car.

Christened the Hoonicorn RTR, the tube-frame Mustang->ke428 is powered by a naturally aspirated, 6.7-liter V-8 from Roush Yates making a ridiculous 845 horsepower. It is mated to a six-speed gearbox that then powers an all-wheel-drive setup. A hydraulically operated handbrake gives Block his drifting abilities while the 295/30R-18 Pirelli Trofeo R tires do the “gripping.” Those are similar to the tires found on the Camaro Z/28, but these are specially formulated for the Hoonicorn. Harder rubber means a touch less grip for all the sideways action, plus they come from Pirelli with Ken Block's name stamped on them.

The engine is mounted behind the front axle, giving it a front mid-engine design that translates into a wonderfully balanced machine. The suspension is comprised of fully independent control arms at each corner. The tough bits are machined from billet aluminum to give the car added lightness and strength.

Things inside the Hoonicorn are purpose-built. It has a hand-made carbon-fiber dashboard with Hoonigan-branded gauges, a large display screen that shows gear selection, and of course that massive handbrake lever.

All told, Block’s ridiculous Mustang is a work of modern motoring art that showcases just how wild horsepower and AWD can be.
