The Jaguar Mark IX is a four-door luxury saloon car announced 8 October 1958[4] and produced by Jaguar Cars between 1958 and 1961. It was generally similar to the Mark VIII it replaced, but had a larger, more powerful 3.8 litre engine, 4-wheel disc brakes, and power assisted recirculating ball steering among its mechanical improvements.
Visually the early versions were identical in exterior appearance to the Mark VIII except for the addition of a chrome "Mk IX" badge to the boot lid. Later versions had a larger tail-lamp assembly with an amber section for traffic indication, visually similar to the tail-lights of the smaller Jaguar Mark 2.
It was replaced by the lower and more contemporary-styled Mark X in 1961.
Features
A four-speed manual system transmission was standard. Options included overdrive and a Borg Warner three-speed automatic box, the most popular choice.[5]
