I paraphrased this from the kneeslider.
The Hyanide and Baal design concepts were part of the Michelin Challenge Design in 2006.
heres a back shot of the Baal
Both the Hyanide and Baal designs are based on a bendable rubber track. The vehicles are steered with your hands and feet.
They were designed to accept a mass produced 500cc ATV engine.
The Baal concept was thought to be the sort of vehicle that could be used in the Paris-Dakar or Baja races.
The German designers are Tilmann Schlootz and Oliver Keller
