Who would have thought that it would be Walmart to design a futuristic truck? The retailer has over 7,000 tractor trailers in its fleet, and they're aiming to make them more efficient. Their latest ultra-aerodynamic Walmart Advanced Vehicle Experience or WAVE concept is lighter and more fuel efficient than any other truck on the market.

It can also run on almost any fuel, except nuclear power that is. The company has just begun testing the WAVE truck, and it is powered by a unique micro-turbine hybrid powertrain. It is capable of running on diesel, biodiesel, natural gas and possibly more. It can also run like an electric car, relying on a set of on-board batteries.

The truck is 20 percent more aerodynamic than the current vehicles in Walmart's fleet and it features a center mounted driver's seat wrapped in large windows. It has LCD displays providing views around the truck.

Check out the video below:

For now, there's no word when WAVE will become part of Walmart's official fleet. But imagine the cost savings they will have when they launch this futuristic concept. [Walmart via Inside EVs]
