We recently saw a rendering for the purely-speculative Audi Avatar, which was based on the outlandish vehicles seen in some futuristic racing video games. A new set of renderings takes the unreal racing game concept a bit further and imagines an entire league that uses hyper-efficient racing vehicles sprinting around a course while using just one liter of fuel. As we know from VW's 1-liter concept vehicle, in the right vehicle, a liter of fuel can take you quite a distance.
Designed by Moritz Martin, the 1 Liter Racing League would be run in unusual locations (think shallow water and beaches) in order to mimic "the effortless gliding of skim boards" on some patches of the course. The wheels can retract in order to "surf" over wet patches and the cars have "a rear wheel-mounted air nozzle for frictionless steering during slides." Check out the renderings in the gallery below.
