If you have yet to watch Ken Block tearing up the streets of LA in Gymnkhana 7, stop what you are doing and watch it here. You'll probably want a lie down after that, but then you should return to watch Chris Harris explain the nutty engineering that has gone into building the 845-hp Hoonicorn. Block and his team of Hoonigans claims this is a 1965 Mustang, but apart from the roof, A- and B-pillars, everything is bespoke.

Under hood, a 6.7-liter Roush Yates V8 sends 845 hp and 720 lb-ft of torque to all four wheels via a six-speed manual normally seen on Dakar rally cars. The handbrake disconnects the front drivetrain for improved donut making, while custom Pirelli rubber create plenty of smoke and allow for sideways mayhem. We could go on, but Chris Harris will take it from here.
