The 43 bhp, 948 cc OHV engine (coded 9CC) was derived from the Austin A35 and Morris Minor 1000 models, also BMC products, but upgraded with twin 1 inch SU carburettors. The rack and pinion steering was derived from the Morris Minor 1000 and the front suspension from the Austin A35. The front suspension was a coil spring and wishbone arrangement, with the arm of the Armstrong lever shock absorber serving as the top suspension link. The rear axle was both located and sprung by quarter-elliptic leaf springs, again with lever-arm shock absorbers and top links. The wheels were 13" fitted with 520X13 crossply tyres or upgraded with 145HR13 Pirelli Cinturato radial tyres. There were no exterior door handles; the driver and passenger were required to reach inside to open the door. There was also no boot lid, owing to the need to retain as much structural integrity as possible, and access to the spare wheel and luggage compartment was achieved by tilting the seat-backs forward and reaching under the rear deck, a process likened to potholing by many owners, but which resulted in a large space available to store soft baggage.
