As you can see in the video above, aluminum is the latest thing in sport car body frames. Ferrari is working with Alcoa on the aluminum "space frame" which weighs just 440 pounds, one third the weight of a steel frame. The way the frame is put together is also very important. Tesla worked with Lotus on a "bonded" aluminum frame that can easily be picked up with one hand. Don't miss the end of the video because I included an odd clip of Tesla showing their battery. Seems Tesla won't let you see inside of their battery because it's "proprietary technology."
