as part of the 1000 pound car design challenge at this year’s la auto show, general motors advanced design california
designed the lightweight cadillac aera. the aera would weigh exactly 1000 pounds and only need refueling every
1000 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.
