The eco-friendly Cadillac Aera weights only 1,000 pounds and its main advantage is economy.
The car will save you a lot of money because it will require refueling every 1,000 miles.
It is worth mentioning that designers thought about making the body of the vehicle from mono-formed 3D lattice, a very strong material.
The car was developed to run on a zero-emission motor that makes use of compressed air for propulsion. The engine uses air from a composite air storage tank.
It would be interesting to note that the compressed air vehicle is driven with the help of a wireless system that eliminates the need of using heavy electrical components.
