Mercedes-Benz came up with the Ener-G-Force to fit the theme of Highway Patrol Vehicle 2025. The original G-Wagen was introduced in 1979 as a civilian version of a military vehicle, which did not take much imagination to envision a civilian version of the Ener-G-Force.
The Mercedes-Benz Ener-G-Force comes in many different elements which already seen in the G-Class. Few changes including the sunk-in headlights, long and flat roofline, rectangular taillights, turn signals/running lights mounted atop the front fenders.
One of the most interesting feature of the concept is the roof rack. It looks like a cargo rack that could be used for a safari. It is actually a concept to store rain water in tanks to then be transferred to a converter that creates hydrogen to power the fuel cells. Battery are built into the rocker panels, and the hypothetical range for this conceptual system is 500 miles of zero-emission driving. A roof-mounted scanner that adjusts the suspension to best fit the road conditions and terrain. The Ener-G-Force was one of six entrants for the 2012 LA Design Challenge, and the winning design will be announced on November 29 as a part of the LA Auto Show.
