Mercedes Benz have responded to the 2012 Los Angeles Design Challenge to create the “highway patrol car of 2025” with this completely desirable off-roader based on the iconic G Class.

The ‘ener-G-force’ fuel cell SUV concept is an idea of the future of environmentally friendly off-road vehicles that ambulances and policemen might be using.

Bleeding awesome, I say!

So here’s how it works (at least in theory). Obviously it’s a zero emission vehicle which stores recycled water on the roof in tanks. This water is then transferred to the ‘hydro-tech converter’ which converts the natural resources in to usable hydrogen for the fuel cells.

The energy is stored in batteries stored in the side skirts of the car, that or replaceable batteries. These change color as the charge decreases, letting the driver know it’s time for a change.

Drive 500 miles on the four wheel hub motors driving each wheel. The car also has a “Terra Scanner” on the rood which permanently scans the surroundings and is thus able to adjust suspension parameters for maximum traction on the respective surfaces.
