The work moved to a disused bus depot on Watling Street in Fazeley. On 3 June 1935, the first Reliant was delivered. Powered by a single-cylinder air-cooled 600 cc J.A.P. engine, the driver sat centrally on the vehicle astride the engine, much like a motorcyclist. The single-cylinder engine left the Reliant under-powered. In March 1936, a two-cylinder, water-cooled J.A.P. engine and an increase to 8 cwt (407 kg) gross vehicle weight was released. The driver no longer sat astride the engine and the vehicle gained more conventional forward-facing seats in the front. The first improved eight cwt twin-cylinder model was delivered on 16 March 1936.
