    Jaguar
    Jaguar Cars Ltd., known simply as Jaguar, is a British luxury car manufacturer, headquartered in Whitley, Coventry, England. A wholly owned subsidiary of the Indian company Tata Motors Ltd., it is operated as part of the Jaguar Land Rover business.

    Jaguar was founded as the Swallow Sidecar Company by Sir William Lyons in 1922, originally making motorcycle sidecars before evolving into passenger cars. The name was changed to Jaguar after WWII to avoid the unfavourable connotations of the SS initials. Following a merger with the British Motor Corporation in 1968, subsequently subsumed by Leyland, which itself was later nationalised as British Leyland, Jaguar was listed on the London Stock Exchange in 1984, and became a constituent of the FTSE 100 Index until it was acquired by Ford in 1989. Jaguar has, in recent years, manufactured cars for the Prime Minister, the most recent delivery being of a XJ model on 11 May 2010. The company also holds Royal Warrants from HM Queen Elizabeth II and HRH Prince Charles.

    Jaguar cars today are designed in Jaguar Land Rover's engineering centres at the Whitley plant in Coventry and at their Gaydon site in Warwickshire, and are manufactured in Jaguar's Castle Bromwich assembly plant near Birmingham.

    The Swallow Sidecar Company was founded in 1922 by two motorcycle enthusiasts, William Lyons and William Walmsley. In 1935 the SS Jaguar name first appeared on a 2.5 litre saloon, sports models of which were the SS 90 and SS 100.

    Cash was short after the Second World War and Jaguar sold to Rubery Owen the plant and premises of Motor Panels, a pressed steel body manufacturing company which had been acquired in the late 1930s when growth prospects had seemed more secure. Nevertheless, Jaguar achieved relative commercial success with their early post war models; times were also tough for other Coventry-based auto-makers and the company was able to buy from John Black's Standard Motor Company the plant where Standard had built the six-cylinder engines it had been supplying to Jaguar.

    Jaguar made its name by producing a series of eye-catching sports cars, such as the XK 120 of 1949, developed into XK 140 and XK 150, and the E Type (or XKE in the US) of 1961. These were all successful and embodied Lyons' mantra of "value for money". They were successful in international motorsport, a path followed in the 1950s to prove the engineering integrity of the company's products.

    Jaguar's sales slogan for years was "Grace, Space, Pace", a mantra epitomised by the record sales achieved by the MK VII, IX, Mks I and II saloons and later the XJ6.

    The core of Bill Lyon's success following WWII was the Twin Cam Straight Six Cylinder Engine—a design conceived pre-War and realised while design staff at the Coventry plant were dividing their time between fire-watching (Coventry being a prime Luftwaffe target) and designing the new power plant.

    To place this in context, benchmark for pre-war racing and competition engines was the "Double Knocker", or Twin Cam engine: Jaguar's new engine was a hemispherical cross-flow cylinder head with valves inclined originally at 60 degrees (inlet) 45 degrees (exhaust) and later standardised to 90 degrees for both inlet and exhaust.

    As fuel octane ratings were relatively low from 1948 onwards, three piston configuration were offered: Domed (High Octane), Flat (Medium Octane), and Dished (Low Octane).

    The main designer, William "Bill" Heynes, assisted by Walter "Wally" Hassan, was determined to design the Twin OHC unit. Bill Lyons agreed over misgivings from Hassan. The sheer concept of applying what had hitherto been considered a racing or low-volume and cantankerous engine, needing constant fettling into reasonable volume production saloon cars was brave.

    The subsequent engine was the mainstay powerplant of Jaguar, used in the XK 120, Mk VII Saloon, Mk I and II Saloons and XK 140 and I50. It was also employed in the E Type, itself a development from the race winning and Le Mans conquering C and D Type Sports Racing cars refined as the short-lived XKSS, a road-legal D Type.

    Few engines have demonstrated such ubiquity and longevity: the Twin OHC "XK Engine", as it came to be known, was used in the Jaguar XJ6 saloon from 1969 through 1992, and employed in a J60 variant as the power plant in such diverse vehicles as Scorpion tanks, the Scimitar armoured personnel carrier, Fox Milan reconnaissance and Fox Scout armoured vehicles, the Ferret, and the Stonefield four wheel drive all-terrain lorry. Properly maintained, the standard production XK Engine would achieve 200,000 miles of useful life.

    Two of the proudest moments in Jaguar's long history in motor sport involved winning the Le Mans 24 hours race, firstly in 1951 and again in 1953. The 1955 victory was somewhat overshadowed by the tragic events that occurred. Later in the hands of the Scottish racing team Ecurie Ecosse two more wins were added in 1956/57.

    In spite of such a performance orientation, it was always Lyons' intention to build the business by producing world-class sporting saloons in larger numbers than the sports car market could support. Jaguar secured financial stability and a reputation for excellence with a series of elegantly styled luxury saloons that included the 3 & 3½ litre cars, the Mark VII, VIII, and IX, the compact Mark I and 2, and the XJ6 and XJ12. All were deemed very good values, with comfortable rides, good handling, high performance, and great style.

    Combined with the trend-setting XK 120, XK 140, and XK 150 series of sports car, and nonpareil E-Type, Jaguar's elan as a prestige motorcar manufacturer had few rivals. The company's post-War achievements are remarkable considering both the shortages which rove Britain, raw materials still being allocated by the Ministry of Supply, and the state of metalurigcal development of the era.

    In 1951 Jaguar leased Browns Lane from the The Daimler Motor Company Limited, which would quickly become its principal plant.[9] Daimler - not to be confused with Daimler-Benz or Daimler AG - was purchased from the holding company BSA in 1960. From the late 1960s, its marque was used as a brand name for Jaguar's most luxurious saloons.

    The Jaguar XJ is a full-size luxury saloon and the company's flagship model. There has been an XJ in production since 1968 with the first generation being the last Jaguar car to have creative input by the company's founder, Sir William Lyons. In early 2003, the third generation XJ arrived in showrooms and while the car's exterior and interior styling were traditional in appearance, the car was completely re-engineered. Its styling attracted much criticism from many motoring journalists who claimed that the car looked old-fashioned and barely more modern than its predecessor, many even citing that the 'Lyons line' had been lost in the translation from Mark 2 into Mark 3 XJ, even though beneath the shell lied a highly advanced aluminium construction that put the XJ to very near the top of its class.

    The Jaguar XF is a mid-size executive car introduced in 2008 to replace the out-going S-Type in the company's line-up. In January 2008, the XF was awarded the What Car? 'Car of the Year' and 'Executive Car of the Year' awards. The XF was also awarded Car of the Year 2008 from What Diesel? magazine. Engines available in the XF are a 3.0 litre V6 diesel or petrol and a 5.0 litre V8 supercharged called the XFR, or naturally aspirated V8 petrol, and - in the US - a 4.2L V8. Prices range from £29,900 to £62,600 in United Kingdom.

    The Jaguar XK is a luxury grand tourer introduced in 2006, where it replaced the Jaguar XK8. The XK introduced an aluminium monocoque bodyshell, and is available both as a two-door coupé and two-door cabriolet/convertible. The XK price ranges from £60,000 - £71,000 in United Kingdom.

    Jaguar began producing R models in 1995 with the introduction of the first XJR. Powered by a supercharged 6 cylinder engine, the car produced approximately 322 horsepower. With the revamped line of engines, the powerplant would be based on an eight-cylinder engine with supercharger from 1997 to present. The 1997–2003 XJR produced 370 horsepower (276 kW) and 385 pound-feet (522 N·m) of torque, taking the car to 60 mph (97 km/h) in just under 5.3 seconds. The new aluminium bodyshell from 2004 to 2009 and increased power to 400 hp (298 kW) and enhanced computer systems decreased the time to 60 mph (97 km/h) to a little over 5 seconds. Starting after year 2000, XJRs were equipped with Jaguar's CATS (Computer Active Technology Suspension) which helped firm up the ride in sporty driving without compromising comfort during day-to-day use.

    The Jaguar S-Type, first appeared in 1999 and stopped production in 2008. It has now been replaced by the Jaguar XF. Early S-Types suffered from reliability problems but those were mostly resolved by the 2004 model year.[37]

    The Jaguar X-Type was a compact executive car launched in 2001, while the company was under Ford ownership. Sharing its platform with a 2000 Ford Mondeo, the X-Type lasted just one generation. The model ceased production in 2009.

    The Jaguar company started production with the pre-war 1.5, 2.5 and 3.5 litre models which used engines designed by the Standard Motor Company. The 1.5 litre four-cylinder engine was still supplied by Standard but the two larger six-cylinder ones were made in house. These cars have become known unofficially as Mark IVs.

    The first post war model was the 1948 Mark V available with either 2.5 or 3.5 litre engines and had a more streamlined appearance than pre-war models, but more important was the change to independent front suspension and hydraulic brakes.

    The big breakthrough was the launch in 1948 of the XK120 sports car, powered with the new XK twin overhead camshaft (DOHC) 3.5 litre hemi-head six-cylinder engine designed by William Heynes, Walter Hassan and Claude Baily. This engine had been designed at night during the war when they would be on fire watch in the factory. After several attempts a final design was achieved. That is until owner William Lyons said "make it quieter". The car had originally been intended as a short production model of about 200 vehicles as a test bed for the new engine until its intended home, the new Mark VII saloon, was ready. The XK120's exceptional reception was followed in 1954 by the introduction of the derivative XK140, and a much revised XK150.

    Jaguar launched E-Type in 1961. ‎ Along with sports cars, Jaguar maintained a strong place in the upscale saloon car market. Introducing the large Mark VII in 1951, a car especially conceived for the American market, Jaguar was overwhelmed with orders. The Mark VII and its successors gathered rave reviews from magazines such as Road & Track and The Motor. In 1956 a Mark VII won the prestigious Monte Carlo Rally.

    In 1955, the "2.4-Litre" saloon (subsequently known as the 2.4 Mark 1) was the first monocoque (unitary) car from Jaguar. Its 2.4-litre short-stroke version of the XK engine provided 100 milliponds (980 µN; 1.5 grf) performance. In 1957, the 3.4-litre version with disk brakes, wire wheels and other options was introduced, with a top speed of 120 mph (190 km/h). In 1959, an extensively revised version of the car with wider windows and 2.4, 3.4, and 3.8-litre engine options became the Mark 2. The 3.8 Mark 2 was popular with British police forces for its small size and 125 mph (201 km/h) performance.

    The Mark VIII of 1956 and Mark IX of 1958 were essentially updates of the Mark VII, but the Mark X of 1961 was a completely new design of large saloon with all round independent suspension and unitary construction.

    The independent rear suspension from the Mark X was incorporated in the 1963 S-Type which closely resembled the Mark 2, and in 1967 the Mark 2 name was dropped when the small saloon became the 240/340 range. The 420 of 1966, also sold as the Daimler Sovereign, put a new front onto the S-type, although both cars continued in parallel until the S-Type was dropped in 1968. The Mark X became the 420G in 1966.

    Of the more recent saloons, the most significant is the XJ (1968–1992), still the definitive Jaguar saloon car for many.[who?] From 1968 on, the Series I XJ saw minor changes, first in 1973 (to Series II), 1979 (Series III), a complete redesign for 1986/1987 in XJ40, further modifications in 1995 (X300), in 1997 with V8-power (X308), and a major advance in 2003 with an industry-first aluminium monocoque-chassis (X350). The most luxurious XJ models carried either the Vanden Plas (US) or Daimler (rest of world) nameplates. In 1972 the 12-cylinder engine was introduced in the XJ, while simultaneously being offered in the E Type.

    1992 saw the introduction of the mid-engined, twin-turbo XJ220. Designed to compete head-on with the Ferrari F40 and Porsche 959 supercars, the XJ 220 was powered by a 542 bhp (404 kW; 550 PS) V6 that propelled it to 350 km/h {217 mph}.

    The company has had major success in sports car racing, particularly in the Le Mans 24 Hours. Victories came in 1951 and 1953 with the C-Type, then in 1955, 1956 and 1957 with the D-Type. The manager of the racing team during this period, Lofty England, later became CEO of Jaguar in the early 1970s. Although the prototype XJ13 was built in the mid-1960s it was never raced, and the famous race was then left for many years, until in the mid-1980s when Tom Walkinshaw's TWR team started designing and preparing Jaguar V12-engined sports prototypes for European sports car races. The team started winning regularly from 1987, and with increased factory backing the team won Le Mans in 1988 and 1990.
