Rally Car driver and DC Shoes co-founder, Ken Block, created viral sensations with his Gymkhana webisodes. The latest installment was just released yesterday and it's just as insane and intense as the previous clips. Check out the video of Block hooning the 600+ HP Ford Fiesta on the streets of San Francisco.

GYM5, shot on the actual streets of San Francisco, California features a focus on fast, raw and precise driving action. Filmed over four days, the city of San Francisco was turned into Ken Block's personal gymkhana playground. DC Shoes also provided fellow DC athlete and longtime Ken Block friend, Travis Pastrana, to make a cameo appearance on his dirtbike as Block hoons S.F. in his most incredible Gymkhana yet.
