Jaguar XJ (X300)

Rear of a Jaguar XJ6

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

The Sovereign model used the AJ16 engine in either 3.2 L or 4.0 L 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.

A 1994 Jaguar XJ 4.0 Sport

To attract younger buyers, Jaguar offered a Sport model with wider 8-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.

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]

For the 1996 model year, a long wheelbase version of the body shell was introduced, adding an extra 5 inches (130 mm) 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 X330 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 X330 Majestic, although unlike the XJ40 they were never badged as such. The X330 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 X330 carried a much smaller price premium over the standard models, as compared to its predecessor.[3]

Front of a Jaguar XJR

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 321 hp (239 kW; 325 PS) and 378 lb⋅ft (512 N⋅m) with the use of an Eaton M90 supercharger and an air-water intercooler. The 0 to 97 km/h (0 to 60 mph) acceleration time was generally around the 5.9 for the manual transmission car to 6.6 second 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.

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 6.0 L 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]

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]

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.

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.
