Issigonis' design included the same ideas he had proposed for the Ten before the war: independent suspension, rack and pinion steering, and unitary construction. In the case of the Mosquito, Issigonis was inspired by the Citroën Traction Avant, a car he greatly admired, and he proposed using torsion bars on each wheel, as on the Citroën, rather than the usual coil spring system. The French car, launched in 1934, had also been an early example of the use of rack and pinion steering.
