Background
In 1968, aged around 14, a Scottish school boy submitted a hand drawn car design to Jaguar in Browns Lane, Coventry in the hope of securing his dream job. Amazingly enough he did indeed achieve his dream of leading the Jaguar design team. His name was Ian Callum, and in the spirit of accuracy, it did take him until 1999 to realise his dream, with him becoming Director of Design for Jaguar in the summer of that year. With Callum filling the role following the unexpected death of Geoff Lawson, he arrived to an in-tray positively groaning under the weight of high-stakes design priorities.
One of these was to replace the range topping XJ saloon, the origins of which hailed right back to 1968. The original XJ was the work of Jaguar’s spiritus rector, Sir William Lyons, and represented in his own words “the closest to what I always had in mind as my ideal car." No pressure then. Despite this Callum pressed ahead with the all new X351 with the innovative design being frozen in 2008 and slated for production during 2010. The X351 was a complete departure from its forebears despite carrying forward an element of the X350’s floor pan. It also doubled down on its predecessor’s aluminium monocoque with the addition of magnesium and composite alloys, at least 50% of which were recycled in origin. As a result the X351 was the lightest car in its class, shaving at least 100kgs from the mass of equivalent rivals from Munich and Stuttgart.
Right from the Jay Leno hosted launch at London’s Saatchi Gallery in July 2009 the model everyone was talking about was the 510PS V8 supercharged Supersport. Its dramatic sub 5 second 0-60mph capability was counterpointed perfectly by the serenity of its luxuriously appointed and tech laden cabin. Within a year the XJ in X351 form became a prime ministerial transport for David Cameron. In 2010 the first XJ Sentinel was delivered to Downing Street complete with its bomb resistant doors, bullet proof glass and armoured underside. Ultimately 120,000 X351s would be built between 2010 and 2019 with just a tiny fraction of these being the deeply desirable 5-litre, V8 supercharged Supersport.
