For this year's LA Design Challenge, Mercedes-Benz introduced the Ener-G-Force Highway Patrol Vehicle 2025. Mercedes says its new concept can be seen as a futuristic interpretation of the G-Class from which its borrows many design cues. Who says future, says electric, and the Ener-G-Force has four independent electric motors at each wheel. Motivation is provided by hydrogen powered fuel cells that allow the car to have a 805 Km (500 miles) range. The winning design will be announced on November 29 as during the LA Auto Show.
