General Motors advanced design California,designed the lightweight Cadillac Aera. The Aera would weigh exactly 1000 pounds and only need refueling every1000 miles. Seating four, the concept vehicle uses a body structure composed of a mono formed 3d lattice that is sturdy without the weight of extra parts.
This lattice design is based off structures found in nature and all the components stem from the main structure. The aera runs on a compressed air engine that has a 10000 psi composite air storage tank.
The driving is also done using a wireless system that cuts out heavy electrical components.
