To celebrate the 50th anniversary of Calty Design Research Incorporated, Toyota has decided to showcase some previously unseen concepts developed by the design studio throughout the years. These concepts, which had been kept under wraps, include an early proposal for the Land Cruiser FJ40 and a trailer concept from 1975. However, it’s the pair of supercars that have attracted the most attention.

In 1983, Calty revealed a mid-engine performance car with scissor doors, known as the “MX-1.” Unlike a mere design sketch, the white supercar was actually built as a full-size scale model. While some high-ranking Toyota executives had the chance to see the car, the project was never greenlit for production. Interestingly, the original MR2 was introduced just a year later with its engine positioned behind the seats, although it didn’t match the caliber of the MX-1.
