The Red Bull Soapbox Race will return to the UK for the first time since 2004 when this summer teams take to the ramps at Alexandra Palace in London.
The gravity race features hand-built karts designed to thrill the crowds with either flat-out speed or insane decorations. Teams are judged on creativity, personality and ingenuity.
Participants reach up to 40mph on a specially constructed track, which will take place on July 14th at the iconic Alexandra Palace in London.
In this gallery we have selected some of our favourite karts from previous, insane events.
