Invention of the Cube Car. This box-like car, designed by French-Vietnamese designer and engineer Quasar Kahn, was produced in limited numbers between 1967 and 1968 by Universal Power Drives of Perivale, Middlesex, who also made the Unipower sports car. The car had a unique cube-like appearance, with sliding glass doors. It is probably unique amongst car designs in being wider than it is long. The seats were plastic and inflatable. The engine was a four cylinder 1100 cc BMC model with automatic transmission. Modified Mini subframes carried the suspension components and 10-inch Mini wheels were used.
