Weight is the enemy of fuel efficiency, literally an anchor weighing our cars down and causing them to consume more gas. Alas, Americans keep demanding more from our cars; more power, more room, more safety, and of course more cupholders. I do not envy today’s engineers who somehow have to fit everything into the car and still make it weigh less than a tank.
What if we could go back to a simpler, lighter time though? Design Los Angeles invited car makers from the world over to build and design a fully-functioning, four-passenger car with modern conveniences that weighs in at just 1,000 pounds. Meet the contenders.
First up is the Cadillac Aera from General Motors. Yes, GM participated in this design study, and their car is one of the sharpest in the bunch. Decidedly futuristic, the Aera uses a 3D lattice mono-formed frame that optimizes strength and minimizes weight, utilizing designs found in the grouping of bubbles. The Aera gets power from a compressed air engine, and as a Cadillac I expect it would be rather well appointed in the luxury department.
