Austin FX4 - Design and Launch

Design and Launch

The FX4 London taxi was the successor to the Austin FX3, which was produced between 1948 and 1958. In its day the FX3 was the most widely used taxi in London. Like the FX3, the FX4 was designed by Austin in collaboration with Mann and Overton, the London taxi dealership that commissioned it (and paid for half of its cost) and Carbodies, the coachbuilder that built the body and assembled the cab ready for sale. The design team included Albert Moore from Austin’s engineering division, Jack Hellberg from Carbodies and David Southwell of Mann and Overton. The original design was by Austin’s Eric Bailey and it was engineered for production by Carbodies' Jake Donaldson. It would be the first London taxi to go into production that had four doors.

Like the FX3, the FX4 had a separate chassis, but with independent front suspension and dual-circuit hydraulic brakes. The first FX4, registration number VLW 431, was delivered in July 1958 and went on test with York Way Motors. The official launch was later that year at the Commercial Motor Exhibition.
