The Pinto got well known for a couple of reasons.
One, the classic "exploding in a rear end collision." The design flaw here was that in certain rear collisions, the fuel tank would be pushed into the rear differential. Not only could this rupture the fuel tank, it could also produce a spark. Boom. Lots of cars had this same design in the 70s, with the fuel tank low in the rear, right behind the rear differential.
Two, the infamous Pinto Memo, which did a cost benefit analysis that determined it would be cheaper for Ford to not fix the problem, and just settle whatever cases came up. This very clearly inspired the Fight Club recall formula scene. Take note that the car used in that scene is a Lincoln Town Car, produced by Ford Motor Company.
The kicker for the Pinto recall? What they did to fix it:
- Two sheets of 1/8" plastic, each about 18" square
- Some long zip ties
- Layer the two sheets over the rear diff, zip tie them to the axle
That's it. My dad pointed this out to me in his shop some time in the late 80s or early 90s. He had a Pinto in for an oil change or something, "Hey, let me show you this." It was such a hacky "repair."
