The Austin 3-Litre is a British saloon car that was introduced by Austin at the London Motor Show in 1967. It became apparent that BMC were not geared up to producing the car: few or none seem to have been sold that year, but by July 1968 it was reported that the cars had begun to leave the factory. By that time the square headlights seen at the 1967 motor show had been replaced by conventional round twin headlamp units, and by the time of the October 1968 show the car had also acquired front quarter lights. In July 1968, with cars beginning to emerge from the plant, the manufacturers were asked to detail improvements reportedly implemented since the car's "launch" the previous October. Mention was made of orifice modifications to hydraulic valves in the rear suspension, and it was stated that there was a "new" final drive ratio of 3.9:1, though this was actually the same final drive ratio included in the launch information the previous October.
