A couple years back Gorilla glass said they were going to go into the auto industry next year and they appeared to have a manufacturer lined up. To my knowledge the only car with gorilla glass right now is the BMW i8. Is it possible that Tesla is the manufacturer they had lined up and the delay with the Model X is why there has been a delay seeing Gorilla glass expand in the auto industry? I know gorilla glass is much lighter, but how much of an impact would that actually make on range. It would certainly lighten the load of the falcon wing doors. It is more durable. This would give Tesla the ability to make the windshield extend back to the rear doors, with less fear of replacement cost. I wonder how much of a cost difference there is from traditional glass and if the benefits it provides outweigh the cost.
