The Siddeley Deasy cars were derived from the Deasys with dashboard radiators and pair-cast cylinders introduced for the 1910 season by the old campany under J.D. Siddeley’s management. Two of the four 1912 Siddeley Deasy carmodels – 4 cylinder machines of 1.9- and 2.6-litres’ capacity – were identical to their 1911 counterparts, but the remaining two featured Knight sleeve-valve engines; these Siddeley Deasy cars were the 3.3-litre 18-24 and a big 6-cylinder town carriage, the 24-30 Siddeley Deasy car costing £685 in chassis form. Poppet-valve units were dropped on Siddeley Deasy cars in 1913, when there was a smaller 2.6-litre 14-20 in the Siddeley Deasy car range, and the Siddeley Deasy car company also marketed the BSA-based 13.9hp Stoneleigh with frontal radiator. Electric lighting was standardized on 1914 Siddeley Deasy carmodels, and the Siddeley Deasy car could also be had with electric starters. The amalgamation with Armstrong-Whitworth after World War 1 resulted in the 30hp Armstrong Siddeley.
