Overview: WILD IN THE STREETS. Ken Block built one of the world's wildest Ford Mustangs ever, the 845hp AWD Ford Mustang Hoonicorn RTR. Naturally, he had to make a video to show off what it's capable of - and what better place than the raw streets of Los Angeles. Pretty much what you'd imagine it would be like to be on of the sole survivors in a post-apocalyptic cityscape, equipped with one of the greatest hooning vehicles ever built.
