The Jaguar Mark IX (pronounced mark nine) is a large luxury saloon car produced by Jaguar Cars between 1959 and 1961. It replaced the previous Mark VIII, and differed little in exterior appearance except for the new model name. It was replaced by the longer, wider and lower contemporary-styled Mark X in 1961.
Standard transmission was a four-speed manual system: options included overdrive, but most cars were built with a Borg Warner three-speed automatic box.
Internally, an enlarged-bore 3.8 L (231 in³), 220 bhp (164.1 kW) DOHC straight-6 replaced the previous 3.4 L (210 in³) 190 bhp (141.7 kW) unit. Two SU carburettors were fitted. Four-wheel servo assisted Dunlop disc brakes and recirculating ball power steering were now standard equipment. The torsion bar independent front suspension and leaf-sprung rear live axle were retained from the Mk VIII.
The body was generally similar to its predecessor, but the sunshine roof became a standard fitting for the UK market. The interior was in the same luxurious mode with extensive use of leather, walnut wood trim and deep pile carpet. A range of single and duo-tone paint schemes was offered.
