The Ford Nucleon: the atomic car that stayed a model.
In 1958 Ford showed a car meant to run on a small nuclear reactor at the back, swapped like a battery every 5,000 miles. It was never built. What survives is a 3/8-scale model and a lot of questions. Here is what we actually know, with every fact linked to its source.
A model, not a car. The Nucleon never existed as a full-size car, never had a reactor and never moved under its own power. What exists is a 3/8-scale model. Everything on this site is about that model and the idea behind it.
The short version
The Ford Nucleon was Ford’s 1958 idea for a car powered by a rear-mounted, self-contained nuclear reactor. The Henry Ford
It never went beyond a non-working 3/8-scale model. The Henry Ford (brochure) Ford never actually built a nuclear-powered car, concept or otherwise. Hemmings (Kurt Ernst)
The idea assumed that the problems of reactor size, weight and nuclear risk would eventually be solved. The Henry Ford
The Henry Ford museum calls it more a public relations exercise than serious research and development. The Henry Ford (brochure)
When we checked on 9 November 2026, The Henry Ford listed the model as on loan to the Atomic Museum in Las Vegas. The Henry Ford
