The Jaguar XJ (X300) is a full-size luxury saloon car manufactured by Jaguar Cars between 1994 and 1997. It was the first Jaguar XJ produced entirely under Ford Motor Company ownership, and can be considered an evolution of the outgoing XJ40 generation. Like all previous XJ generations, it features the Jaguar independent rear suspension arrangement. The design of the X300 placed emphasis on improved build quality, improved reliability, and a return to traditional Jaguar styling elements.[2][3]
At the car's launch in October 1994 at the Paris Motor Show, Jaguar marketing material made use of the phrase "New Series XJ" to describe the X300 models. The X300 series represented the result of a £200 million facilities renewal program by Ford.[4] The program introduced state-of-the-art automated body welding robots manufactured by Nissan, and was intended to show the future direction of the British auto industry. The X300 went on to become one of Jaguar's most successful models.[5]

Aesthetically, the X300 received several updates in the design refresh led by Geoff Lawson in 1991. The mostly flat bonnet of the XJ40 was replaced with a fluted, curvaceous design that accentuated the four separate round headlamps. Rear wings were reshaped to accommodate the new wrap-around rear light clusters. Additionally, the separate black-rubber bumper bar of the XJ40 was replaced with a fully integrated body-coloured bumper. The Jaguar leaper bonnet mascot was installed only on cars for non-European markets. These vehicles feature 8 disc tumbler Tibbe lock barrels similar to Ford vehicles at the time, except Ford used a 6 disc lock hence the key blade and barrels being shorter on Ford models. Aston Martin also used the same locks as fitted to these Jaguars.

The interior of the X300 was similar to that found in the XJ40, with some revisions. The seats were updated to have a more rounded profile, wood trim was updated with bevelled edges, and the steering wheel was redesigned. Early X300 cars were built without a front passenger glove-box, due to space constraints caused by the introduction of a front-passenger airbag.
Mechanicals
After the XJ40, what became the X300 was not supposed to happen, as Jaguar's intention was to launch a brand new saloon with a new V8 engine. Ford halted development of the saloon, termed XJ90, and proposed to install its new engine and front and rear ends onto the centre section of the XJ40 model; however, the V8 was not ready, and would not be so until after the X300's successor, the XJ X308.[5]
Jaguar's V12 engine and AJ6 inline-six (AJ16) engine were both available in various X300 models, although they received significant updates. Both engines were fitted with distributorless electronic engine management systems. The V12's new management system was designed by Nippon Denso. The top aluminium cover in the engine's valley was redesigned to house two packs of three coils each, with each coil having two high-tension terminals for a total of twelve. These coilpacks were driven by two Denso ignition modules, which are very similar to Ford EDIS-6 units. The crankshaft in the V12 was switched from a forging to a chill casting. A visibly significant chromed pipe connecting the left and the right banks of the V12 in the XJ40 platform (intended to vent and route the crankcase blow-by gas to the intake plenum) was changed with the introduction of the X300 to an almost invisible design at the top center of the engine underneath a plastic cover that also hides fuel rails and coilpacks.
The 4.0-litre AJ16 inline-6 engine
For the inline 6 cylinder engine, magnesium-alloy valve covers and revised pistons featured in the engine, which was given the designation AJ16. It was found in 4.0L supercharged form in the XJR. The normally aspirated six-cylinder X300 cars used either a ZF four-speed automatic gearbox (4HP-22 on the 3.2L and 4HP-24 on the 4.0L),[6] or a Getrag 290 five-speed manual. The 4HP-22 automatic is mechanically controlled while the 4HP-24 is electronically controlled, allowing 4.0-litre models to offer Normal and Sport modes on a switch by the gear lever. This switch is replaced with a blanking plate on the 3.2L. The supercharged six-cylinder engine in the XJR was normally built with the optional GM 4L80-E four-speed automatic and very few XJRs were ordered with the standard specification Getrag 290.[citation needed] All V12-equipped cars were built with the GM 4L80-E automatic. In certain markets, such as North America, no manual gearbox was offered.
The X300 was the first XJ to be affected directly by Jaguar's takeover in 1990 by the Ford Motor Company. According to David Versical of Automotive News, Ford's influence was evident more in terms of "product development processes than its parts bin". Versical added that the XJ's new "traction control system came via Ford's Mondeo program" and it also featured "a Nippondenso air conditioner sourced through Ford's purchasing channels."[7]
Models
The X300 was available in both short- and long-wheelbase body styles and in various trim levels. Some markets had a limited selection of X300 models or features. For example, the North American XJ6 was only available with the 4.0L engine, and all cars sold there were equipped with alloy wheels, a leather interior, and air conditioning. North America did not receive the Sport, Executive, or Century models, nor was a manual transmission offered. Power folding mirrors were standard in Japan and optional in all other markets except the USA.
XJ6

The base model in the range was the XJ6, which featured the 3.2L version of the AJ16. On these base cars, aluminium alloy wheels, leather upholstery, and air conditioning were all extra-cost options. Later, the 4.0L version of the AJ16 was offered in the XJ6.
Sovereign

The Sovereign model used the AJ16 engine in either 3.2L or 4.0L form, and came equipped with luxury features as standard such as ten-way electric leather seats with three-way memory on the driver's side, cruise control, automatic climate control and a tool kit located under the bonnet. The exterior of the Sovereign was adorned with chromed trim in various locations: on the radiator grille, rear light cluster surrounds, windscreen and rear window surrounds, rain gutters, window frames, and boot-lid plinth.
XJ Sport

To attract younger buyers, Jaguar offered a Sport model with wider 18-inch wheels, revised seats, and stiffer suspension. The Sport kept the matte-black window surrounds from the base model, and is identified by Sport badges on the B-pillars and XJ Sport badging on the rear. The sports suspension, along with the wider wheels, were also available as an option on both SWB and LWB XJ6 and Sovereign models.
Executive
Aimed at a younger market segment, the Executive model was introduced for the 1997 model year and featured leather trim, a wood/leather steering wheel, wide wheels (similar to the Sport model), and air conditioning. It was treated as a run-out specification for the XJ6 and so separate production numbers are not available.[8]
Long Wheelbase (X305)
For the 1996 model year, a long wheelbase version of the body shell was introduced, adding an extra 5 inches (130mm) for rear seat occupants and an extra inch of headroom. This body style was available for all of the classic models (XJ, Sovereign, and XJ12) but not the sport models (XJ Sport and XJR). There were two X305 variants, one with five seats and one with four, which featured a raised centre console between the two adjustable rear seats.
Internally, Jaguar referred to the long wheel base version as the X305 Majestic, although unlike the XJ40 they were never badged as such. The X305 bodies were built on the standard production line, whereas the XJ40 Majestic started as a SWB body which was then taken away and stretched by Project Aerospace in Coventry, before being returned and fitted out by Jaguar Special Vehicle Operations.[9] This meant the X305 carried a premium over the standard models, as compared to its predecessor.[3]
XJR (X306)

The XJR was introduced as a high-performance sport model, and it was Jaguar's first-ever supercharged road car and only the second Jaguar road car to use forced induction, after the Jaguar XJ220, which was turbocharged. The output of the six-cylinder AJ16 engine was increased to 321hp (239kW; 325PS) and 378lb⋅ft (512N⋅m) with the use of an Eaton M90 supercharger and an air-water intercooler. The 0 to 97km/h (0 to 60mph) acceleration time was generally around the 5.9 for the manual transmission car to 6.6second mark for the automatic. The XJR was fitted with larger 17 inches wheels, compared to 16 inches on the rest of the range, along Pirelli P-Zero tyres, with 10 mm lower firmer suspension and traction control. Almost all of the 6,547 XJR production cars were built with the optional GM 4L80-E automatic gearbox, although the Getrag 290 five-speed manual gearbox was the standard offering; only 268 were made, 102 in RHD for the United Kingdom market and the rest in LHD mainly in Europe with Italy taking 57.

Cosmetically, the XJR differed from the standard cars with a body-coloured grille surround, mesh grille insert, body-coloured boot-lid plinth, larger exhaust outlets, special five-spoke Sport alloy wheels, and XJR badging. Rain gutters and window surrounds were matte black, except on North American models where they were polished stainless steel. This generation of the XJR model carries the code name X306. It is also sometimes referred to as the XJR6 to differentiate it from the later V8-engined Jaguar XJ (X308) XJR.
XJ12 (X305)
The XJ12 model, which carries the code name X305 along with the short wheel base Daimler Double Six, featured the same trim level of the Sovereign but was powered by the 6.0L version of the Jaguar V12 engine. It is visually differentiated by the rear boot-lid XJ12 badge, a V12 insignia inlaid on the passenger-side dashboard wood panel, a V12 badge on each B-pillar, chromed door mirrors and a gold-coloured Jaguar crest at the top of the radiator grille surround. Only available transmission was a 4-speed automatic GM 4L80-E. In the United States market, this generation of the XJ12 was available only as model years 1995, which were all short-wheelbase, and 1996, which were all long. The X305 was equipped with an On-Board Diagnostics System; however, it failed to fully meet the OBD-II specifications, which became mandatory for the 1996 model year in the United States. With a special dispensation for that model year expired, no 1997 model year X305 models were sold in North America. In 2001, the United States EPA and Jaguar Cars entered into a settlement that extended the emissions warranty on 1995 and 1996 model year XJ12 saloon cars to 14 years or 150,000 miles due to their non-compliant NipponDenso Engine Management System, which was unable to provide continuous misfire monitoring, a requirement for OBDII compliance.[10]
While the similar Daimler Double Six came with 225/60-16 tyres on 7-inch wheels and comfort suspension as standard, the XJ12 came with 225/55-16 tyres on 8-inch wide wheels and sports suspension, which explains the height difference between the two models. The last Jaguar to be powered by a V12 engine was a green LWB XJ12, registered P60 SOV, which left the production line on 17 April 1997.[11] It was placed in the Jaguar Daimler Heritage Trust museum in Coventry before its closure,[12] and was moved to the Jaguar Collection at the British Motor Museum at Gaydon in Warwickshire.[13]
Daimler/Jaguar Vanden Plas
A Daimler Double-Six
The Daimler name was applied to the highest trim level of the X300 cars, and featured all the chrome brightwork found on the Sovereign cars, plus chromed door mirrors, chromed door handles, and a fluted radiator grille surround & boot (trunk) finisher. Most of the optional extra features on the X300 range were all standard for the Daimler, such as heated front seats, heated front screen, sunroof & cruise control, plus for the Daimlers only fluted leather door pockets, picnic tables for rear passengers on the back of the front seats and special marquetry veneer. The Daimler Six model was equipped with the AJ16 engine, and the Daimler Double Six with the V12; both available in short or long wheel base.

In some markets, such as North America, the name Jaguar Vanden Plas was used instead of Daimler. Vanden Plas X300 cars in the United States after MY 1995 are all built on the long-wheelbase body shell, although they were only available with the six-cylinder engine, leaving the V12 available solely in the XJ12 model for that market. 1995 Vanden Plas cars are all short wheelbase cars.
On April 26, 1997, the Daily Pilot newspaper in Orange County, California ran a Lexus of Westminster advertisement which mistakenly advertised a used sapphire blue "1995 Jaguar XJ6 Vanden Plas" for the remarkably low price of US$25,995, instead of the intended price of US$37,016. When the dealership refused to honor the advertised price, and later sold the car to someone else for US$38,399, the ensuing lawsuit went up on appeal to the Supreme Court of California. The high court held on July 30, 2001 that the dealership had formed a contract for sale of the vehicle under the doctrine of offer and acceptance, but also held that the dealership could avoid enforcement of the contract on the ground of mistake.[14]
Daimler Century
In 1996, the Century model was introduced to commemorate the centennial of the Daimler name. The Century was equipped with all features and upgrades available on the X300 cars, plus chromed wheels, special exterior paint, and electrically adjustable rear seats.
Daimler Corsica concept
A single two-door XJ convertible was built in 1996 to commemorate Daimler Company's centenary. The concept car, called the Daimler Corsica, was based on the Daimler Double-Six saloon and can seat four. The prototype, which lacked an engine, had all the luxury features of an XJ saloon car but a shorter wheelbase. It is painted in a colour called Seafrost, which was later discontinued. The Daimler Corsica was named after the 1931 Daimler Double-Six Corsica. The concept was a one-off, and may have been intended for limited production beginning in 1997. The car has made a limited number of appearances at car shows and events since 1996. It has most recently appeared at the Belfast Sports Car Show in January 2004. The Daimler Corsica prototype is owned by the Jaguar Daimler Heritage Trust, who have commissioned it to operate as a fully functional road-legal car.[15] It was on display at their museum at Browns Lane in Coventry but is now on display in the Jaguar Collection at the British Motor Museum at Gaydon, Warwickshire. The car has also been displayed at Harewood House as part of the Jaguar Enthusiasts' Club show.
Jaguar is the sports car and luxury vehicle brand of Jaguar Land Rover, a British multinational car manufacturer with its headquarters in Whitley, Coventry, England. Jaguar Cars was the company that was responsible for the production of Jaguar cars until its operations were fully merged with those of Land Rover to form Jaguar Land Rover on 1 January 2013.
The Ford Anglia is a small family car that was designed and manufactured by Ford UK. It is related to the Ford Prefect and the later Ford Popular. The Anglia name was applied to various models between 1939 and 1967. In total, 1,594,486 Anglias were produced. It was replaced by the Ford Escort.
The Jaguar XJ is a series of mid-size/full-size luxury cars produced by British automobile manufacturer Jaguar Cars from 1968 to 2019. It was produced across four basic platform generations with various updated derivatives of each. From 1970, it was Jaguar's flagship four-door model. The original model was the last Jaguar saloon to have been designed under the leadership of Sir William Lyons, the company's founder, and the model has been featured in countless media and high-profile appearances.
An evolution of the 1964 DOHC prototype “XJ13” engine, the Jaguar V12 engine is a family of SOHC internal combustion V12 engines with a common block design, that were mass-produced by Jaguar Cars for a quarter of a century, from 1971 to 1997, mostly as 5.3‑litres, but later also as 6‑litres, and 7‑litre versions that were deployed in racing. Except for a few low-volume exotic sports car makers, Jaguar's V12 engine was the world's first V12 engine in mass-production. For 17 years, Jaguar was the only company in the world consistently producing luxury four-door saloons with a V12 engine. The V12 powered all three series of the original Jaguar XJ luxury saloons, as well as its second generation XJ40 and X305 successors.
The AJ6, and the similar AJ16, are inline-6 piston engines used by Jaguar cars in the 1980s and 1990s. The AJ6 was designed to replace the successful and long-used Jaguar XK6 engine, and was introduced in 1984. It was only the third all-new engine ever designed by the company. The AJ16 evolution was replaced in 1996 with the Jaguar developed AJ-V8 engine.
The Jaguar XJ-S is a luxury grand tourer manufactured and marketed by British car manufacturer Jaguar Cars from 1975 to 1996, in coupé, fixed-profile and full convertible bodystyles. There were three distinct iterations, with a final production total of 115,413 units over 20 years and seven months.
The Jaguar Mark X, later renamed the Jaguar 420G, was British manufacturer Jaguar's top-of-the-range saloon car for a decade, from 1961 to 1970. The large, luxurious Mark X not only succeeded the Mark IX as the company's top saloon model, but radically broke with both its predecessor's styling and technology.
The Jaguar XJ220 is a two-seat sports car produced by British luxury car manufacturer Jaguar from 1992 until 1994, in collaboration with the specialist automotive and race engineering company Tom Walkinshaw Racing. The XJ220 recorded a top speed of 217 mph (349 km/h) during testing by Jaguar at the Nardo test track in Italy. This made it the fastest production car from 1992 to 1993. According to Jaguar, an XJ220 prototype managed a Nürburgring lap time of 7:46.36 in 1991 which was faster than any production car lap time before it.
The Mercedes-Benz W140 is a series of flagship vehicles manufactured by Mercedes-Benz from 1991 to 1998 in sedan/saloon and coupe body styles and two wheelbase lengths. Mercedes-Benz unveiled the W140 S-Class at Geneva International Motor Show in March 1991, with the sales starting in April 1991 and North American launch was on 6 August 1991.
The Jaguar Mark 2 is a mid-sized luxury sports saloon built from late 1959 to 1967 by Jaguar in Coventry, England. The previous Jaguar 2.4 Litre and 3.4 Litre models made between 1955 and 1959 are identified as Mark 1 Jaguars.
Daimler Sovereign was a name applied by British manufacturer Jaguar Cars to a sequence of luxury automobiles built by it but carrying the Daimler badge between 1966 and 1983.
William 'Bill' Munger Heynes CBE, born in Leamington Spa, was an English automotive engineer.
The Jaguar 420 and its Daimler Sovereign equivalent were introduced at the October 1966 London Motor Show and produced for two years as the ultimate expression of a series of "compact sporting saloons" offered by Jaguar throughout that decade, all of which shared the same wheelbase. Developed from the Jaguar S-Type, the 420 cost around £200 more than that model and effectively ended buyer interest in it, although the S-Type continued to be sold alongside the 420/Sovereign until both were supplanted by the Jaguar XJ6 late in 1968.
Jaguar's independent rear suspension (IRS) unit has been a common component of a number of Jaguar production cars since 1961, passing through two major changes of configuration up to 2006 and last used in the Jaguar XK8 and Aston Martin DB7. This article concentrates on the first generation Jaguar IRS, which firmly established the marque's reputation for suspension sophistication, combining as it did smooth ride with excellent roadholding and low levels of noise, vibration, and harshness (NVH). The two generations overlap in time due to their being used in both full size and sports models that were updated at different times.
The Jaguar XJ (X351) is a saloon car built by British manufacturer Jaguar Cars, later known as Jaguar Land Rover, from 2010 to 2019. It is the fourth-generation of the Jaguar XJ model. Referred to internally within Jaguar as the X351, it was announced in 2009 before going on sale in 2010, and combines revised styling with underpinnings of the previous Jaguar X350 generation. The model was discontinued in 2019. It is the final generation of the XJ, after the electric Jaguar XJ was cancelled in February 2021.
The Jaguar XJ (X350) is a full-size four-door luxury sedan/saloon manufactured and marketed worldwide by Jaguar Cars for model years 2003–2009 as the third generation of the Jaguar XJ saloon, carrying the internal designation X350 and the internal designation X358 following its 2007 intermediate facelift. Both the X350 and X358 were available with a six-speed automatic transmission, a range of petrol and diesel engines, numerous trim levels, and short wheelbase (2003–2009) or long wheelbase (2005–2009) car body configurations. Extended-length models were the longest vehicles Jaguar had manufactured.
The Jaguar XK8 is a grand tourer launched by Jaguar Cars in 1996, and was the first generation of a new XK series. The XK8 was available in two-door coupé or two-door convertible body styles with the new 4.0-litre Jaguar AJ-V8 engine. In 1998, the XKR was introduced with a supercharged version of the engine. In 2003, the engines were replaced by the new 4.2-litre AJ34 engines in both the naturally aspirated and supercharged variations. The first-generation of the XK series shares its XJS-derived platform with the Aston Martin DB7, with both cars tracing their history back to an abandoned Jaguar development study in the mid-1980s known as XJ41/XJ42, which had been mooted to be known as the F-Type.
The Jaguar XJ (XJ40) is a full-size luxury saloon manufactured by Jaguar Cars between 1986 and 1994. It was officially unveiled on 8 October 1986 as an all-new, second generation of the XJ to replace the Series III, although the two model ranges were sold concurrently until the Series III was discontinued in 1992. The XJ40 used the Jaguar independent rear suspension arrangement, and featured a number of technological enhancements, such as electronic instrument cluster. It was the last car to be developed independently by Jaguar, and also the last to have been developed largely within the lifetime of the company's founder Sir William Lyons, who died shortly before its release.
The Jaguar XJ (X308) is a full-size luxury saloon car manufactured and marketed by Jaguar Cars for years 1997–2003 across two generations and featuring the Jaguar AJ-V8 engine and Jaguar independent rear suspension. It was the third and final evolution of the Jaguar XJ40 platform that had been in production since 1986. It was preceded by the Jaguar XJ (X300).
