The Peugeot XRC Concept was independently designed by Brazilian artist Teago Aiello to be used as a rally car. It was rendered on 3D imaging software, so sadly, it does not exist in real-life even as a concept. But it's fun to dream.
Aiello doesn't hide the fact that it is designed to operate exactly like a large scale RC car, even including that fact in the name of the design.
It looks like it could really work -- although the vehicle sits a little low to the ground. It appears to have some heavy duty suspension, but even so, going over rough terrain like that depicted in the renderings looks like to would absolutely destroy the undercarriage.
Top Gear would have a field day if they got to test drive this gorgeous looking car.
