Background
Jaguar and the Ministry of Supply shook hands on the former’s lease of the latter’s Browns Lane factory in 1951. Browns Lane was a “shadow factory” in Coventry, which was under the management of Daimler during WWII and utilised for producing aero engines for the war effort. This newfound square footage was sufficient for Jaguar to produce their existing range as well as to diversify in new and exciting directions.
On the back of this deal Jaguar set out to mix things up a bit in the middle-weight executive saloon segment. In 1952, Project Utah was launched to design the new Jaguar entrant to compete with the aging Humbers, weighty Standard Vanguards, and the bank manager’s favourite Rover P4 which then dominated the segment. Utah bore fruit in 1955 in the shape of the Jaguar 2.4 Litre and, later, the Jaguar 3.4 Litre. These curvy upstarts turned the segment on its head with their modern unitary construction, a first for Jaguar, and independent front suspension. These sporting compact executive cars only retrospectively became known as the “MKI,” of course, following the arrival of the MKII in 1959.
The MKI benefitted from a modicum of over-engineering by dint of its innovative design. This being Jaguar’s first model to utilise a unitary construction, engineers made the bodyshell stronger than it needed to be…..just to be on the safe side. They also added rubber mountings galore to keep occupants well insulated from any un-Jaguar-like vibration or noise. The 2.4 Litre featured a new, short-stroke version of the redoubtable XK, six-cylinder, DOHC engine.
These factors no doubt contributed, with many others, to the immediate popularity of the MKI. Well over 16,000 right hand drive 2.4 Litre MKIs would go on to be produced before the car’s replacement by the MKII in 1959. A model that had previously lived in the shadows of XK’s, E-Types and 3.8 Litre MKIIs is today enjoying some well-deserved time in the sun. The MKI has latterly become sought out as an important watershed model in Jaguar’s history as well as an “origins” car for many subsequent iconic models.
