The Jaguar XJ is a luxury sedan sold under the British Jaguar marque. The XJ was launched in 1968 and has served as the Jaguar flagship model for most of its production span which continues through to today. The original model was the last Jaguar saloon to have had the input of Sir William Lyons, the company's founder.

The XJ6, using 2.8 L (2790 cc/170 in³) and 4.2 L (4235 cc/258 in³) straight-six cylinder versions of Jaguar's renowned XK engine, replaced most of Jaguar's saloons - which, in the 1960s, had expanded to four separate ranges. Apart from the engines, the other main component carried over from previous models was the widest version of Jaguar's IRS unit from the Mark X.
An upmarket version was marketed under the Daimler brand and called the Daimler Sovereign, continuing the name from the Daimler version of the Jaguar 420.
The "XJ" designation was from the car's code name during development, standing for Experimental Jaguar.
The car was introduced in September 1968. Power assisted steering and leather upholstery were standard on the 2.8 L 'De Luxe' and 4.2 L models and air conditioning was offered as an optional extra on the 4.2 L. Daimler versions were launched in October 1969, in a series of television advertisements featuring Sir William. In these spots, he referred to the car as "the finest Jaguar ever". An unusual feature, inherited from the Jaguar Mark X, was the provision of twin fuel tanks, positioned on each side of the boot / trunk, and filled using two separately lockable filler caps: one on the top of each wing above the rear wheel arches.
In March 1970 it was announced that the Borg-Warner Model 8 automatic transmission which the XJ6 had featured since 1968 would be replaced on the 4.2 litre engined XJ6 with a Borg-Warner Model 12 unit. The new transmission now had three different forward positions accessed via the selector lever, which effectively enabled performance oriented drivers to hold lower ratios at higher revs in order to achieve better acceleration. "Greatly improved shift quality" was also claimed for the new system.
In 1972 the option of a long wheel base version, providing a modest increase in leg room for passengers in the back, became available.
The XJ12 version, featuring simplified grille treatment, and powered by a 5.3 L V12 engine (coupled to a Borg Warner Model 12), was announced in July 1972: the car was presented at that time as the world's only 12-cylinder four door car, and, with a top speed "around 140 mph" (225 km/h) as the "fastest full four-seater available in the world today". Although it had, from the car's launch, been the manufacturer's intention that the XJ would take the twelve cylinder engine, its installation was nonetheless a tight fit, and providing adequate cooling had evidently been a challenge for the engineers desiginging the installation. Bonnet/hood louvres such as those fitted on the recently introduced 12 cylinder E Type were rejected, but the XJ12 featured a complex "cross-flow" radiator divided into two separated horizontal sections and supported with coolant feeder tanks at each end: the engine fan was geared to rotate at 1¼ times the speed of the engine rpm, subject to a limiter which cut in at a (fan) speed of 1700 rpm. The fuel system incorporated a relief valve that returned fuel to the tank when pressure in the leads to the carburetters exeeded 1.5 psi in order to reduce the risk of vapour locks occurring at the engine's high operating temperature, while the car's battery, unusually, benefitted from its own thermostatically controlled cooling fan.
3,235 of these first generation XJ12s were built. As with the six cylinder cars, an upmarket version, this time called the Daimler Double-Six, became available later, reviving the Daimler model name of 1926-1938.
