Mark 1, Mark 2, 240, 340, Daimler V8 1955-68
Medium sized saloon cars first introduced in 1955 and known at introduction as Jaguar 2.4 Litre which was later joined by US market destined Jaguar 3.4 Litre. Retrospectively referred to as Mark 1 following the introduction in October 1959 of the Jaguar Mark 2.
The Mark 2 introduced the 3.8 Litre engine alongside the 2.4 Litre and 3.4 Litre but this was largely removed from manufacturing except for special order high performance in 1967 when the other models were rebadged Jaguar 240 and Jaguar 340
The Daimler V8 was the first Daimler car to be based on a Jaguar platform and sadly the last to feature the hemispherical head V8 engine which was first used in the Daimler SP250 sports car.
Medium sized saloon car that was a technically more sophisticated development of the Mark 2, offering buyers a more luxurious alternative without the size and expense of the Mark X. The S-Type retained the 3.4 Litre and 3.8 Litre engines seen in the Mark 2 which its sold alongside the as well as the Jaguar 420 following its release in 1966.
The Jaguar 420 (pronounced "four-twenty") was 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 until supplanted by the Jaguar XJ6 late in 1968.
Mark X, 420G, 1961–70
The Jaguar Mark X (Mark ten), 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 succeeded the Mark IX as the company's top saloon model, and was primarily aimed at the United States market. The company hoped to appeal to heads of state, diplomats and film stars.
Introduced in the same year as Jaguar's iconic E-Type, the Mark X impressed with its technical specification and innovations. Combined with the 3.8-litre, triple carburettor engine as fitted to the E-type, it gave Jaguar's flagship a top speed of 120 mph and capable handling at less than half the price of the contemporary Rolls-Royce Silver Cloud
Despite press acclaim from both sides of the Atlantic, the Mark X never achieved its sales targets. When Jaguar decided to replace its entire saloon range with a single new model, the resulting XJ6 of 1968 used the Mark X as a template.
XJ Series 1, 2 and 3, XJC.(1968-92)
The Jaguar XJ is the name of a series of full-size luxury cars sold by the British automobile brand, Jaguar Cars since 1968. Since 1970 they have been Jaguar's flagship. The original model was the last Jaguar saloon to have had the input of Sir William Lyons, the company's founder, and the model has been featured in countless media and high-profile appearances.
- Series 1 (1968–73)
The XJ6, using 2.8-litre and 4.2-litre (4,235 cc or 258.4 cu in) straight-six cylinder versions of Jaguar's renowned XK engine, and replaced most of Jaguar's saloons – which, in the 1960s, had expanded to four separate ranges.
In 1972 the option of a long-wheelbase version, providing a 4" increase in leg room for passengers in the back, became available.
The XJ12 version was announced in July 1972, featuring simplified grille treatment, and powered by a 5.3 L V12 engine was presented at that time was the world's only mass-produced 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".
A total of 98,227 Series I models were produced.
- Series 2 (1973–79)
Commonly referred to as the "Series II", the XJ line was facelifted in autumn 1973 for the 1974 model year. The 4.2 L I-6 XJ6 (most popular in the United Kingdom) and the 5.3 L V12 XJ12 were continued with an addition of a 3.4 L (3,442 cc or 210.0 cu in) version of the XK engine available from 1975.
The Series II models were initially known for their poor build quality, which was attributed to Jaguar being part of the British Leyland group along with massive labour union relations problems that plagued most of industrial England in the same time period. The same cannot be said for the models produced in Nelson, New Zealand.
A total of 77,501 Series II models were produced.
Initially the Series II was offered with two wheelbases, but at the 1974 London Motor Show Jaguar announced the withdrawal of the standard wheelbase version. New American safety regulations meant the front bumper had to be raised, which necessitated the lowering of the radiator grille. The most significant change was in the interior where the instruments were positioned in front of the driver, and instrument and switch lighting was by fibre optics which was a first for British cars. By this time the first customer deliveries of the two-door coupe, which retained the shorter standard-wheelbase (and which had already been formally launched more than a year earlier) were only months away.
- Series 3 (1979-92)
Facelifted again, known as the "Series III." And using the long-wheelbase version of the car, the XJ6 incorporated a subtle redesign by Pininfarina.
There were three engine variants, including the 5.3 L V12, the 4.2 L straight-six and 3.4 L straight-six. The larger six-cylinder, and V12 models incorporated Bosch fuel injection (made under licence by Lucas) while the smaller six-cylinder was carburetted. The smaller 3.4 L six-cylinder engine was not offered in the US
In 1981 the 5.3 V12 models received the new Michael May designed "fireball" high compression cylinder head engines and were badged from this time onwards to 1985 as HE (High Efficiency) models.
Production of the Series III XJ6 continued until early 1987 and on till 1992 with the V12 engine.
A total of 132,952 Series III models were produced.
- XJ Coupé (1975-78)
The two-door XJ coupés with a pillarless hardtop body called the XJ-C was built between 1975 and 1978. The car was actually launched at the London Motor Show in October 1973, but was not ready for production until 1975 when the world was suffering significant economic problems. The coupé was based on the short-wheelbase version of the XJ with elongated doors.
A few XJ-Cs were modified by Lynx Cars (powered) and Avon (manual) into convertibles with a retractable canvas top, but this was not a factory product. Lynx conversions (16 in total) did benefit of powered tops. Both six and twelve-cylinder models were offered
The delayed introduction, the labour-intensive work required by the modified saloon body, the higher price than the four-door car, and the early demise promulgated by the new XJ-S, all ensured a small production run.
A total of 9.378 XJ-C models were produced.
