Probably the best part of being a concept, is that you get to use your imagination a little bit more than you would in an actual production model. At least, until you have to figure out how to actually get what you conceptualized to work in the real world. While we've seen plenty of other concept vehicles in the past work on all sorts of things, this new design from Volvo, called the Air Motion Concept, is a design that would have the vehicle running on nothing but the air.
Teh Air Motion Concept is powered by compressed air, and compressed air only. It's held within a tank, and accessed when the vehicle needs power. Considering that the whole vehicle is powered by air, and the frame is constructed from carbon fiber, it's no surprise that the vehicle would weigh somewhere in the ballpark of 1,000 pounds. There's no combustion engine under the hood, either. Instead, designers implemented a pneumatic motor.
When asked at the LA Auto Show how you would refuel the vehicle that runs on air, Volvo said that they believe there will be wind-powered stations ready to fill up your Air Motion Concept when the time comes.
