The first XJ-S appeared in 1975 as a 1976 model. Power came from the Jaguar V-12 petrol engine with a choice of a manual or automatic transmission, but the manual was soon dropped. V-12 automobiles were unusual at the time, with notable others coming from Italian luxury sports car makers Lamborghini and Ferrari. The specifications of the XJ-S compared well with both Italian cars; it was able to accelerate to 60 mph (97 km/h) in 7.2 seconds and reach 150 mph (240 km/h). The first series of XJ-S cars had a Borg-Warner Model 12 transmission with a cast iron case and a bolt-on bell-housing. In 1979 GM Turbo-Hydromatic 400 transmissions were fitted. The TH400 transmission was an all aluminium alloy case with an integrated non-detachable bell-housing.
Jaguar's timing was not good; the car was launched in the wake of a fuel crisis, and the market for a 5.3 litre V12 grand tourer was very small. The styling was also the subject of criticism, including the buttresses behind the windows. German authorities feared these would restrict rearward vision, and refused to give the model (along with a similarly adorned contemporary Lancia model) type approval: it was for a time necessary instead for German XJS buyers to obtain type approval for each individual car when registering it.[4] Such fears were ill founded, since in reality the rear visibility was very reasonable, with only the frontmost top edges of the buttresses being visible, when looking rearward.
Jaguar did seize promotional opportunities with the television series The New Avengers and Return of the Saint. The New Avengers featured Mike Gambit (Gareth Hunt) who drove an XJ-S. Return of the Saint saw Simon Templar (played by Ian Ogilvy) driving an early XJ-S with the number plate "ST 1". Miniature versions were made by Corgi and proved popular. A decade and a half before, Jaguar had turned down the producers of the earlier Saint series when approached about the E-type; the producers had instead used a Volvo P1800.
Responding to criticisms that the XJ-S was not a worthy E-type successor, Pininfarina revealed a sporty show car in 1978 based on XJ-S mechanicals and called Jaguar XJSpider.[5] The car never went into production.
6-cylinder version and a convertible
In 1983, a new 3.6 litre engine débuted Jaguar AJ6 engine I6, as well as a new cabriolet version, the XJ-SC. In the XJ-SC, the coupé's rather small rear seats were eliminated making it only a 2-seat car. The XJ-SC was not a full convertible but had a non-removable centre targa-type structure and fixed cant rails above the doors. The rear quarter windows remained as well.Between 1983 and 1987 the 6 cylinder engined cars were only available with a 5-speed manual transmission (Getrag 265), with a 4-speed automatic (ZF 4HP22) offered from 1987 onwards (along with improved fuel injection as used on the XJ40). The earlier, manual models were not imported by Jaguar into the United States, which had to wait until the facelift manual 4 litre XJS coupé and convertible were available; even then they were sold only in low numbers. A limited number of earlier 5-speed AJ6 cars did however enter the US as grey market personal imports.[citation needed]
A V12 XJ-SC emerged in 1985.
1991–1996
The car was re-engineered in 1991 and renamed XJS. All XJSs from this time are referred to as "facelift" models. The rear side windows appeared enlarged (although the body glass aperture was actually the same size as the earlier car), and the buttresses stayed, as designer Geoff Lawson argued that they were part of the car's character. The car got a new 4 litre version of the AJ6. In 1992 a 4 litre convertible was added to the range. The V12's capacity was enlarged to 6 litre in May 1993 (227 kW (304 hp)). At the same time the car benefited from a revision to the rear brakes, they were now fitted with outboard rear disc brakes, instead of the more complicated inboard items on previous models. With the introduction of the 6.0 litre V12, the transmission was also updated to a GM 4L80E with a 4th gear overdrive, whilst the automatic 4 litre models continued with the electronic ZF4HP24E transmission. A 2+2 convertible was also introduced, as was a customised insignia line. At the same time the car received more aerodynamic front and rear bumpers. 1992 thru 1994 were the only years the 6-cylinder with 5-speed manual transmission XJS was exported to the United States. Exact production figures are unknown, though it is likely there are fewer than ten.In April 1994 substantial revisions were made to the 4 litre AJ6 engine which became the 4.0 litre AJ16 with coil on plug ignition being amongst the most noticeable of the changes. In 1995, the final specification changes were made and the car was referred to as the Celebration model to celebrate the 60th year of the Jaguar company. Celebration cars are easily identifiable by the diamond turned wheels, Jaguar embossed seats and distinctive wooden steering wheel. These latest cars are the most desirable of all the later XJSs, especially the convertibles. The 6 litre V12 had all but disappeared by this time and was only available during the last year of production by special order. The car was discontinued in 1996, after 21 years in production. It was replaced by the XK8.
Motorsport
For 1977, the "Group44" racing team had a very successful season in Trans Am with a race car based on the actual production XJ-S chassis and running gear. The team won the series' 1977 drivers' championship cup for Bob Tullius but missed winning the manufacturer's title by two points (only one Jaguar was competing in the Trans-Am series compared to many more Porsche entrants). In 1978, a purpose-built tube-frame "silhouette" style XJS race car was constructed which greatly reduced the weight compared to the full production chassis car campaigned in 1977. This silhouette car had only the production car's roof panel as the sole piece of factory XJS sheetmetal on the car. Group 44 succeeded in again capturing the driver's championship for Bob Tullius and also captured the manufacturer's title as well, by entering Brian Fuerstenau driving the 1977 car at some venues to gain additional manufacturer's point for Jaguar. The silhouette car survived and has surfaced recently in the SVRA historic sports race series. The 1977 factory chassis race car is believed to still be in the hands of Group 44's Bob Tullius.In April 1979 a Jaguar XJS driven by Dave Heinz and Dave Yarborough was entered into Cannonball Baker Sea-To-Shining-Sea Memorial Trophy Dash, widely known simply as the Cannonball Run. They completed the 2,863 miles (4,608 km) from New York to Los Angeles in a record time of 32 hours and 51 minutes, a record that stood for 4 years, until it was beaten by David Diem and Doug Turner in a Ferrari 308. Diem and Turner covered the same distance in 32 hours and 7 minutes on the US Express, an unofficial successor to the Cannonball Run.[9]
In 1984 Tom Walkinshaw captured the Drivers’ title of the European Touring Car Championship with a Group A version of the XJ-S, entered by TWR. During the championship season the TWR team had also won the Spa 24 Hours race with an XJ-S driven by Tom Walkinshaw, Hans Heyer and Win Percy.
In 1985, XJ-S drivers John Goss and Armin Hahne won the James-Hardie 1000 for Group A Touring Cars at Bathurst, New South Wales in Australia. This car was the third of a trio of XJS's entered for the race by TWR. Walkinshaw and Percy finished third in the lead Jag after oil line problems late in the race.
Today the XJS continues to be extensively campaigned in club level motorsport both in the United Kingdom and overseas. Best known of the race series is probably the Jaguar Enthusiasts' Club XJS championship, currently in association with Toyo Tires. Their championship has now been running for over a decade, offering an affordable entry into club motorsport in the UK, and continuing to attract large grids of this unlikely racing car. Cars compete in various states of modification, from barely modified road cars through to full race-specification cars built in homage to the great TWR specials.
