The Chrysler Royal is an automobile which was produced by Chrysler Australia from 1957 to 1963. After investing in tooling to stamp body panels for the 1954 P25 series Plymouth locally, and with Chrysler headquarters in Detroit unwilling to assist in the costs of retooling for the new US models, Chrysler Australia made the decision to develop their own range, using as much of the existing tooling as possible, whilst also realising that the new car had to appear as different as possible. The doors and basic structure of the P25 sedan was retained, and with input from Australian and American Chrysler designers, the 1955 US Plymouth front sheetmetal was adapted to the P25 body and the rear quarter panels redesigned. They also added a wraparound rear windscreen, which caused development problems with Pilkington Glass, the Australian suppliers, who struggled to get the correct curved shape.
The first version of the Chrysler Royal, the AP1, was introduced in May 1957. It was a development of the American Plymouth P25 design  of 1954 which had itself been produced by Chrysler Australia as the P25 Plymouth Cambridge and Cranbrook, the D49 Dodge Kingsway and the SP25 De Soto Diplomat. Original designations for the three different designs were AD1 for the Dodge, AS1 for the DeSoto and AP1 for the Plymouth. Plans to market the updated version under these three names were dropped late in the development program and the new model would be sold only as the Chrysler Royal thus revising a name used by Chrysler in the US market  from 1937 to 1950. The design chosen for the final model was that proposed for the Plymouth variant, thus the AP (Australian Plymouth) designation was adopted, and changed to stand for Australian Production. The Royal differed from the P25 in using front and rear mudguards similar to those on the 1956 US Plymouth and a rear window which was larger than that of the P25. The AP1 was produced as a Royal four-door sedan, a Plainsman four-door station wagon, and a Wayfarer two-door coupé utility, and was offered with two versions of Chrysler's valve-in-block straight-6 engine: a 230.2 cu in (3.8 L) with manual transmission and a 250.6 cu in (4.1 L) with the Powerflite 2-speed automatic. Chrysler's 313 cu in (5.1 L) polyspherical-head V8 was introduced as an option during the AP1 model run. V8 powered Royals were popular with the South Australia Police, where they were employed as Highway Patrol cars.
A revised Royal, the AP2 was introduced in late 1958. This series featured a new grille and unusual rear styling with additional “saddle fins” grafted on to the exiting tailfins. The AP2 was available as a Royal four-door sedan, a Plainsman four-door station wagon, and a Wayfarer two-door coupé utility. The Plainsman station wagon was dropped from the range during the AP2 series. The choice of six cylinder and V8 engines continued, with the V8 identified by a V shaped emblem in the grille and a small V8 badge on the rear quarter.
The final version of the Royal was the AP3 which was introduced during 1960. The new series was easily distinguished from its predecessors by its vertically stacked quad headlamps and triple tail lights similar to those of the 1959 US Desoto models. A new pressing for the roof panel was also used. Chrysler's 3-speed Torqueflite automatic transmission replaced the 2-speed PowerFlite automatic of the AP2. Production ceased in 1964. The AP3 was available as a Royal four-door sedan and a Wayfarer two-door coupé utility. The choice of six cylinder and V8 engines continued, with the V8 identified by twin side trim strips (the six cylinders having only one side trim strip) and a small V8 badge on the rear quarter.
Chrysler Plainsman & Wayfarer
In addition to the Royal sedan, Chrysler Australia also produced the following Royal based derivatives:
- Chrysler Plainsman Station Wagon (AP1 and AP2) from 1957 to 1959 
- Chrysler Wayfarer 1/2-ton coupé utility (AP2 and AP3) from 1958 to 1961 
- Chrysler Royal chassis/cowl were produced to allow for custom bodywork to be fitted, for example ambulance/hearse 
All three series of Royals were very popular with ambulance services throughout Australia with many ambulance services basing their fleet on the Royal chassis. The Victorian Civil Ambulance Service in Melbourne is one such service that employed vast numbers of Royals as did many country areas in Victoria. Royal ambulances were also used throughout New South Wales, Queensland, South Australia and Tasmania. Various coachbuilders were contracted to transform Royals into ambulances, using different specifications depending on District requirements. Some vehicles used hand formed steel bodywork over timber frames, others used newly developed fibreglass technology. In 1957 Commonwealth Engineering (ComEng) began development of the first fibreglass ambulance body in Australia, in conjunction with the Central District Ambulance in Sydney. The first vehicle was completed in June 1958, after Central District agreed to replace its entire fleet with fibreglass bodied Royals constructed by ComEng. The use of fibreglass bodywork provided a vehicle that was believed to be tougher, quicker to build, and easier to repair and resulted in a weight saving of around 560 pounds (254 kilograms). As well as using the available chassis/cowl configuration, ambulances were also converted from sedans, Wayfarer coupe utilities, and at least one was converted from a Plainsman station wagon. The Royal chassis was also popular with undertakers as a basis for hearse conversion.
