The FJ, of monocoque construction, broadly followed the silhouette of its predecessor, but featured a bolder horizontal styled front grille, along with comfort and decoration upgrades in a new sedan model named the 'Holden Special'.
Originally specified as 60 bhp (45 kW) achieved at 3,800 rpm, the claimed maximum power output from the six-cylinder engine was increased to 65 bhp (48 kW) achieved at 4,000 rpm.
In 1955 the car underwent a mild interior facelift for the Holden Special sedan, along with a variation in paint and trim options. The FJ series was progressively replaced by models from the Holden FE series from July 1956 to May 1957 with a total of 169,969 examples produced.
There are nearly 20 specific FX-FJ Holden Car Clubs of Australia with members committed to preserving these iconic Holdens. These clubs organise a national gathering for FX-FJ Holden enthusiasts every second year.
