It's all a juggling game. Weight is part of every design choice Elio makes. But how much (forgive me) weight is given to weight will vary with the particular issue at hand.They don't dent so easy. Yeah, I've seen the commercial where they drop pavers into the bed. Have you seen Honda's version? Not a dent or chip. You won't see Chevy doing that. Elio probably went to steel body panels for cost and availability's sake. I doubt weight savings had anything to do with the body choice. Now, the frame, on the other hand...
For instance, in evaluating the radiator, weight might be more of a consideration than it would be in evaluating the rear wheel axle, because in that case strength trumps weight savings though both are important.
I would think that in the case of the body panels weight is very important, but so are strength, durability, and cost. And corrosion resistance, though that is also addressed in painting and galvanizing. Galvanizing does add weight, but it is essential for corrosion resistance. Alas, galvanizing does nothing for strength.
But I wander. The point I'm trying to make is that everything connected to everything else in the Elio, And choice of body panel material is certainly affected by weight.
