Jaguar S-Type (1963)
The Jaguar S-Type is a saloon car produced by Jaguar Cars in the United Kingdom from 1963 to 1968. Announced 30 September 1963 it 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 sold alongside the Mark 2, as well as the Jaguar 420 following its release in 1966. A retro-styled vehicle with the same name was also produced, based on the design of the original S-Type vehicles. History The Jaguar Mark 2 was introduced in 1959 and sold throughout most of the 1960s. It has a live rear axle and is powered by the XK six-cylinder engine first used in the Jaguar XK120 of 1948. In the Mark 2 the engine was available in 2.4, 3.4 and 3.8-litre capacities. In 1961 Jaguar launched two new models. The full size Jaguar Mark X saloon (pronounced ''mark ten'') used Jaguar's new independent rear suspension and a triple SU carburettor version of the 3.8-litre XK engine. The other ne ...

Jaguar XJ13
The Jaguar XJ13 was a prototype racing car developed by Jaguar Engineering Director William Heynes to compete at Le Mans in the mid 1960s. It never raced, and only one was produced. The car has not been officially valued, but a £7 million bid for it was declined by the owners in 1996. It was more than 3 times the price of a Ferrari 250 GTO at the time. Development Jaguar had considered the manufacture of a DOHC V12 engine as far back as 1950, initially for racing purposes, and then developing a SOHC road-going version, unlike the XK, which was designed as a production engine and later pressed into service for racing. The engine design was essentially two XK 6-cylinder engines on a common crankshaft with an aluminium cylinder block, although there were differences in the inlet porting, valve angles and combustion chamber shape. The first engine ran in July 1964. The design structure of a mid-engined prototype was first mooted in 1960 by William Heynes, but it was not until 1965 ...

It is the world's oldest active Endurance racing (motorsport), endurance racing event. Unlike fixed-distance races whose winner is determined by minimum time, the 24 Hours of Le Mans is won by the car that covers the greatest distance in 24 hours. The cars on this track can go up to , and in prior events reaching before track modifications. Racing teams must balance the demands of speed with the cars' ability to run for 24 hours without mechanical failure. The race is organized by the Automobile Club de l'Ouest (ACO). It is held on the Circuit de la Sarthe, composed of closed public roads and dedicated sections of a racing track.

Jaguar V12 Engine
The Jaguar V12 engine is a V12 internal combustion engine produced by Jaguar Cars. The engine was based on a prototype design by Claude Baily for an intended Le Mans car—the Jaguar XJ13. The XJ13 project was terminated in 1966 before the car was ever entered into competition, but under the direction of Jaguar Chief Engineer William Heynes the V12 engine design was reworked by engineers Walter Hassan and Harry Mundy into a production-ready version, first installed in the Series 3 Jaguar E-Type of 1971. The V12 was the second production engine design in Jaguar's history. The all-aluminium block was fitted with removable wet iron liners, complete with single overhead camshaft aluminium heads with two valves per cylinder. It was regarded as one of the premier power plants of the 1970s and 1980s. Development Initial designs for a V12 engine were produced by engineer Claude Baily as early as 1951, with a view to using it in a Le Mans car. Baily's original 8.0 L design used double o ...

Weslake
Weslake & Co also known as Weslake Research and Development was founded by Harry Weslake, described as England's greatest expert on cylinder head design, with premises in Rye, East Sussex, England. Weslake is most famous for its work with Bentley, Austin, Jaguar and the Gulf-Wyer Ford GT40 Mk.I. Early days Harry Weslake was born in Exeter in 1897 to Henry John Weslake, a director of Willey and Co, gas engineers, whom he would join from school. At 16, he modified a Rudge Multi to race at local hill climbing events. In World War I, he joined the Royal Flying Corp, against the wishes of his employers Willey & Co, who wanted him to continue his apprenticeship. When he was demobbed in 1919, he had already received his first patent with his father in 1918 for a device to improve carburettors. However both his parents died shortly after, and with no link to Willey's, Weslake left and set up a workshop with 3 others in Exeter. The workshop marketed his Wex carburettor design, which w ...

Jaguar Mark VIII
The Jaguar Mark VIII is a luxury four-door automobile introduced by the Jaguar company of Coventry at the 1956 London Motor Show. Styling The car shared its wheelbase with its predecessor, the Jaguar Mark VII M, which outwardly it closely resembled. The most obvious change was a new curved one-piece windscreen. Distinguishing visually between the models is facilitated by changes to the front grille and a curved chrome trim strip below the waistline which allowed the factory to offer a variety of two-tone paint schemes. In addition the new car had rear spats that were cut back to display more of the rear wheels. The interior fittings were more luxurious than those of the Mark VII M. Engine and running gear The Mark VIII inherited from its predecessor the 3442 cc straight-six engine which it shared with the Jaguar XK140 that appeared two years earlier. In the Mark VIII, a modified cylinder head known as the 'B' type was used. Although introduced subsequent to the 'C' type ...

Jaguar Mark VII
The Jaguar Mark VII is a four-door luxury car produced by Jaguar Cars of Coventry from 1951 to 1956. Launched at the 1950 British International Motor Show as the successor to the Jaguar Mark V, it was called the Mark VII because there was already a Bentley Mark VI on the market. A version of the Jaguar Mark V with the XK engine had been designated as the Mark VI, but it is thought that only two were built. In its original 1950 form the Mark VII could exceed 100 mph, and in 1952 it became the first Jaguar to be made available with an optional automatic transmission. Mark VIIs were successful in racing and rallying. Mark VII 1950–1954 The Mark VII chassis came from the Jaguar Mark V and the wheelbase remained the same at . The new model's body looked more streamlined, with integrated headlights and mudguards, a two-piece windscreen, and longer rear overhang. As on the Mark V, the rear wheels were partially covered by removable spats. Whereas the Mark V had a prewar p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jaguar Mark V
The Jaguar Mark V (pronounced ''mark five'') is a luxury automobile built by Jaguar Cars Ltd of Coventry in England from 1948 to 1951.

Torsion Bar Suspension
A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, the torsion key, mounted perpendicular to the bar, that is attached to a suspension arm, a spindle, or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length, cross section, shape, material, and manufacturing process. Usage Torsion bar suspensions are used on combat vehicles and tanks like the T-72, Leopard 1, Leopard 2, M26 Pershing, M18 Hellcat, M48 Patton, M60 Patton and the M1 Abrams (many tanks from World War II used this suspension), and on modern trucks and SUVs from Ford, Chrysler, GM, Mitsubishi, Mazda, Nissan, Isuzu, LuAZ, and Toyota.
