The Holden 48-215 is a mid-size car sedan manufactured by the Australian company Holden between November 1948 and October 1953. In January 1951, a coupe utility version, designated 50-2106 and sold as the Holden Coupe Utility, was launched.
This model marked the first General Motors vehicle in Australia to bear the Holden brand. Often simply referred to as "Holden," it acquired the informal nickname Holden FX within GM-H in 1952, used internally to differentiate early models equipped with lever-action shock absorbers from those introduced in 1953 featuring telescopic suspension. Although never officially adopted by Holden, the "FX" designation later appeared in used car listings and became a common term encompassing all 48-215 and 50-2106 variants.
The vehicle’s design originated from Chevrolet in the United States but was considered undersized for the post-war American market. Consequently, it served as the foundation for the uniquely Australian 48-215. Its American roots are visible through its similarity to Chevrolet models of that era, particularly the Fleetline Aerosedan and second-generation Deluxe. Development work commenced in 1944.
Five prototypes
In 1946, three prototypes were handcrafted by a team of American and Australian engineers at General Motors’ Detroit facility. Following rigorous durability and performance trials in the United States, these prototypes were transported to Australia. The first prototype was registered in Victoria as JP-480 on 12 February 1947 and is now preserved within the National Museum of Australia. The second and third prototypes bore registrations JP-481 and JP-482 respectively.
Two further prototypes were constructed domestically in Australia; the first of these carried registration KJ-400. This vehicle was owned by businessman Peter Briggs from 1980 until 2013 and fetched a value exceeding at a Melbourne auction held in 2013. The second Australian-built prototype was registered as KY-442. All five prototypes maintained Chevrolet registrations.
Only prototypes No.1 (JP-480, Seine Blue) and No.4 (KY-442, Gawler Cream) were utilized for official photography.
Due to the absence of an established automotive supplier network in Australia at the time, new manufacturing capabilities were created, including forging plants for crankshafts and foundries for major cast components. To expedite production, certain simplifications were implemented: omission of direction indicators, absence of heating or demisting equipment, and a single centrally mounted rear tail lamp. The relatively mild Australian climate permitted use of a smaller 6-volt battery, helping reduce both weight and cost. Interior appointments were kept basic to achieve a target running weight near , aligning with design objectives.

| 2 | Black | 8-1002-M | 1002 | MG-502 |
| 3 | Black | 8-1003-M | 1003 | MG-503 |

| 10 | Black | 8-1010-M | 1010 | MG-510 |
These ten vehicles served various testing purposes: three were allocated to the Engineering department, five to Manufacturing, one to the General Sales Manager, and one to the managing director, H.E. Bettle.
Mass production
Following departmental approvals of the design, full-scale manufacturing commenced with priority given to supplying Holden dealerships across Australia with showroom models ahead of the official debut. The initial production run predominantly featured black-bodied cars; however, GMH ensured that cream, blue, and grey units were also delivered to each capital city. In total, 68 Holdens were distributed to capital city dealers before the launch.
On Sunday, 21 November, an Open Day event was held exclusively for Fishermans Bend staff and their families, drawing approximately 12,000 visitors. The factory tour included design studios and displayed partially assembled as well as completed vehicles along the assembly line.
Victorian dealers attended the formal launch event at Melbourne’s Oriental Hotel on Friday, 26 November.
Launch event
Prime Minister Ben Chifley officially unveiled the vehicle at Fishermans Bend Social Hall on Monday, 29 November 1948, at 2:30 pm. The ceremony attracted roughly 400 invited guests who witnessed a cream-coloured Holden illuminated by spotlights and accompanied by an orchestra; overall attendance reached about 1,200 official attendees. The car was marketed simply as the Holden, without any specific model designation.
It was equipped with a cast-iron straight-six engine delivering , coupled with a three-speed manual gearbox. Reported acceleration times from ranged between approximately 18.7 and 27.7 seconds depending on sources. Notable features included a dust-resistant body design and a notably tight turning radius.
The coupe utility version (50-2106), derived from the sedan model, was introduced in January 1951; later, in July 1953, the "Business Sedan" taxi variant (initially coded as 48-215-257 and later renamed to 48-217) was added to the lineup. Both these variants were superseded by the Holden FJ series in 1953.
