When we think of materials for a car, seldom do we think of using foam.
That is precisely what Spira is using to make their Automotive X PRIZE entry.
Made of 90% foam, the car gets 100 mpg and reaches speeds of 70mph. It also floats.
Limited production will begin in Thailand sometime soon so this won’t help the American car industry - if it could.
I personally am a little concerned about the safety of this car and handling in higher winds.
