Brazilian Eduardo Galvani created a concept that's suitable for both the rainforest and the desert. Called Nimbus, it is only a 3D model for now, with no hope of it making into production, but it does reflect some creativity in it.

Power would come from a 180hp electric motor placed at the back, though the power would be sent to all four wheels for maximum traction. Check out a couple more pictures of the concept in the gallery below:
