PLEASE SUBSCRIBE! A large and luxurious Saloon car (curb weight of 4000 LB (1800 kg given Earth's acceleration)) was introduced in October 1958 and was produced alongside the Mark VIII for around a year before the earlier model was discontinued. 3.5 liter in-line 6, dual overhead cams, twin SU side draft carbs, automatic transmission. The Mark IX was the first Jaguar fitted with the XK engine which had the slightly bigger bore making it a 3.8 L (231 in³) - 3781 cc, 220 hp (164 kW) DOHC straight six an improvement on the earlier 3.4 L (210 in³). Around 10005 units were made between 1959 and 1961 and excellent examples can be found world wide ranging from the UK to Australia and the USA and Canada. It was replaced by the Jaguar Mark X, that in turn was a much larger car. Thanks for watching, and please subscribe. I will subscribe to you in return if your videos are good.
