Ford F-150 (aluminum body program)

It is cheaper. It's just like bottled water is more expensive than gasoline now. But yes, steel is cheaper than potting soil. I hadn't thought of that analogy before. It's cheap, it's tough, and it's strong. Compared to the other three in the billion-ton-per-year club, it's ten times better. That's why I was saying 30 years ago that we wouldn't have all-aluminum cars for 25 years. And that's true — we didn't have them for 25 years. But four or five years ago, whenever we got the F-150, we now have some all-aluminum cars in high volume. The primary structure in the F-150 is not aluminum, it's steel.
