Mercedes-Benz’s North American R&D team introduced the Ener-G-Force design concept vehicle at this year’s LA Auto Show Design Challenge. Based on the classic G-Class (notice the “G” shaped LED headlights), the off-road vehicle features 20-inch rims, emergency lighting, rear spare-wheel compartment converted to a quick-access tool box, and a “terra-scan” 360-topography scanner on the roof to spot nasty boulders and vehicle-swallowing ditches. The Terra-scan scanner also uses the results to adjust suspension parameters for maximum traction on the respective surfaces. The Ener-G-Force utilizes four wheel-hub motors driven by fuel cells with a “hydro-tech converter” that would generate fuel using recycled water stored in tanks on the roof. The energy generated by this system would be stored in "drawers" accessed through the side skirts which could alternatively house hot-swappable battery packs. The zero-emissions car provides an operating range of about 500 miles.
