The Minissima is a small concept city car that was designed by William Towns (as the Townscar) as his idea for a replacement for the Mini in 1972 and displayed by BLMC on their stand at the 1973 London Motor Show after buying the prototype from Towns.
In common with the Mini it was designed around 10" wheels and the BMC A-Series engine. It is 30" (75 cm) shorter than the Mini and designed to park end-on to the curb (like the Smart Fortwo), having only one door - at the rear. It has four seats, two at the front, front facing, and two facing inwards at the rear.
The Minissina design re-emerged a few years later as a prototype car for the disabled, adapted by engineering firm GKN Sankey by ex Ford engineer Fred Hart. During the engineering process, the layout changed to feature a central driving position in which a wheelchair user would enter through the back door using a fold-down rear ramp, and drive off. The styling was simplified by William Towns to suit mass production and won a Design Council award in 1978, it did not gain government support due to high costs and the project was cancelled.
