Mercedes-Benz unveiled a concept Sports Utility Coupé full of technology meant to squeeze out alternative power from a variety of sources.
One of the most surprising and futuristic aspects of the Vision G-Code is its paint. Called "multi-voltaic silver" finish, the paint is designed to generate power two ways: first, it works like a solar cell, converting sunlight into electricity; secondly, it creates an electrostatic charge when, while driving, the wind buffets the car's surface.
In addition the exterior, the Vision G-Code has other alternative energy features. For example, it has a hybrid engine, but it's not your typical gas-electric engine. Instead, the front and back wheels are each powered by a specific motor. In the back, it's an electric motor, but in the front, a turbocharged hydrogen combustion engine drives the wheels.
Regenerative braking and plug-in technology common on other hybrid vehicles is also here.
The suspension also generates a charge. Mercedes calls it "power on the move," which is a system that recovers energy from even a little bit of bouncing in the suspension.
Inside the car, the future is on full display. A smartphone app starts the car (don't lose your phone or drop in the toilet). Video feeds from a rear-view camera are superimposed onto a heads-up display that provides information useful to the driver.
My favorite part, aside from the powerful paint, are the two electric scooters stowed in a luggage compartment that can take the driver those last few blocks with ease.
