The Holden 48-215, also known unofficially as the Holden FX is a mid-size, six-cylinder sedan which was produced by the Australian automaker, General Motors–Holden's Ltd between November 1948 and October 1953. The 48-215 was the first model from General Motors–Holden's to bear the Holden name.
The design was originally penned in the United States by Chevrolet, but was not used because it was deemed too small for the U.S. market as it developed after the war. Instead the design became the basis of only the 48-215 model. Development of the 48-215 began in 1944.
The five prototypes
Three prototypes were built by hand in 1946 by American and Australian engineers at the General Motors workshop in Detroit. Months of durability and performance testing were undergone in the US before the three prototypes were shipped to Australia. Prototype number one was first registered (as a Chevrolet) in Victoria as JP-480 on February 12, 1947. The only survivor of the prototypes, it is part of the National Museum of Australia collection.
A further two prototypes were built in Australia; all five prototypes were registered as Chevrolets. Only two were used for photographic purposes. They were:
- Prototype number one, JP-480, dark colour—Seine Blue (not Cadillac Blue)
- A car "…generally thought to have been prototype number four", KY-442, light colour—Convoy Grey
In the absence of an established supplier base in Australia for auto-making, new forging facilities had to be set up for producing crankshafts and a new foundry was set up for major castings. In order to hasten the project to production some simplifications were incorporated. There were no direction indicators, there was no provision for heating or demisting, and at the rear there was only a single, centrally positioned, tail lamp. Because of the mild climate in most of the populated areas of the country, it was found possible to save weight and cost by using a relatively small 6-volt 11-plate battery. Interior trim was minimised: weight reduction was pursued "with great vigour" and, in view of the 2247 pound (1020 kg) weight in "running trim", a success.
The ten pilot cars
- April, the production plant at Woodville, South Australia, begins tooling up to make the bodies—these would be identical to the prototypes. (Body number one, painted black, did not become pilot car number one). Also work begins on the engine assembly line at Fishermen's Bend.
- September 1, the decision is made to call the car Holden.
- September 25, engine number 1001 is started up.
- September 30, pilot car number one is completed in the evening. (There was no celebration, as GMH did not designate this vehicle as No. 1 Holden—it came to be known as Old Number One).
- October 19, pilot car number one is registered as MG-501.
All four Holden colours were represented:
|Pilot car No.||Colour||Serial No.||Engine No.||Registration No.|
|1||Gawler Cream (Body No. six)||8-1001-M||1001||MG-501|
These ten cars were used for testing. Three of them went to the Engineering Department, five went to Manufacturing, one went to the General Sales Manager, and one went to the Managing Director, H.E. Bettle.
When all departments were satisfied with the car, volume production began. The race was now on to ensure Holden dealers in all states had cars on their showroom floors before unveiling day. Black bodies dominated the early roll-out but GMH made sure that each capital city also received examples of cream, blue, and grey. Ultimately, 68 Holdens were distributed to the capital cities before unveiling day.
On Sunday, November 21, an Open Day was held to exhibit the entire factory (including the high-security design rooms) and the car itself. But this special preview was not for the public or the dealers—it was for the Fishermen's Bend employees and their families (GMH estimated that 12,000 guests attended). There were partly assembled cars at various stages along the assembly line as well as finished cars for the guests to inspect.
The official launch for Victorian dealers was held at the Oriental Hotel in Melbourne on Friday, November 26.
The official unveiling by Prime Minister Ben Chifley commenced at 2:30pm on Monday, November 29, in the Fishermen's Bend Social Hall. The 400 guests applauded when silver curtains parted to reveal a cream Holden, in a black velvet setting and sparkling under spotlights, as an orchestra played Brahms' Waltz in A-flat. The celebrations at the plant were attended by 1,200 official guests. The Holden was released for sale to the public at Port Melbourne, Victoria. The car was marketed simply as the Holden, without a model name. It had a 132.5 cu in (2,171 cc) cast-iron straight six engine which produced 60 hp (45 kW), connected to a three-speed manual transmission. It managed the 0–60 mph (0–97 km/h) sprint in 18.7 or 27.7 seconds. Sources differ. It also had a dust proof body, and a small 37 ft turning circle.
The 50-2106 coupe utility, based on the 48-215 sedan, was released in January 1951 and in July 1953 the "Holden Business" sedan, essentially a taxi version of the 48-215, was added to the range. The 48-215 and 50-2106 models were replaced by the Holden FJ series in 1953.
