The Mercedes-AMG One is a production reality — not a show car — built to prove F1 hybrid technology can function on public roads. Its layout, powertrain and aerodynamics are derived directly from contemporary Formula One. It sacrifices usability for fidelity. It is not a supercar for driving. It is a rolling validation of a racing specification.
A one-off 1979 concept built to show off Newport Pagnell—and chase a title it never claimed.
The Chrysler Turbine Car was an experimental two-door hardtop coupe designed by Elwood Engel and built by Chrysler with bodywork by Carrozzeria Ghia. It used the A-831 turbine engine, was produced in 55 units between 1963 and 1964, and featured power brakes, power steering, and a TorqueFlite transmission. All were finished in 'turbine bronze' paint.
The Ford RS200 is a purpose-built homologation special: mid-engined, all-wheel drive, plastic-fiberglass body by Ghia, built by Reliant in Shenstone to meet FIA Group B’s 200-unit rule. It exists only to enable a rally car—not as a design statement, luxury product, or road-going evolution.
The Firebird I is a 1953 GM concept car designed by Harley Earl. It was the first gas turbine-powered car tested in the United States. It features a single-seat cockpit under a bubble canopy, a bullet-shaped fiberglass fuselage, short wings, and a vertical tail fin. It was built for the 1953 Motorama show. GM never intended it for production.
