60-463: The Jaguar XK120 is a sports car manufactured by Jaguar between 1948 and 1954. It was Jaguar's first sports car since SS 100 production ended in 1939. The XK120 was launched in open two-seater or (US) roadster form at the 1948 London Motor Show as a testbed and show car for the new Jaguar XK engine designed by Jaguar Chief Engineer William Heynes . The display car was the first prototype, chassis number 660001. It looked almost identical to
120-399: A controversial choice for a "purist" sports car. The Elan sold poorly and was discontinued after three years. The 1996 Lotus Elise , a mid-engined, rear-wheel drive roadster, was much more successful and remained in production until 2021. Roadsters enjoyed a resurgence in the mid-1990s, including the 1989-present Mazda MX-5 , the 1995-2002 BMW Z3 (succeeded by the 2002-2016 BMW Z4 ),
180-409: A definition. Insurance companies have also attempted to use mathematical formulae to categorise sports cars, often charging more for insurance due to the inherent risk of performance driving. There is no fixed distinction between sports cars and other categories of performance cars, such as muscle cars and grand tourers , with some cars being members of several categories. Traditionally,
240-589: A later option. In addition to wire wheels, upgrades on the Special Equipment (SE) version (called the M version for Modified in the United States) included increased power, stiffer suspension and dual exhaust system. The Motor magazine road-tested an XK120 in November 1949. This pre-production car, chassis number 660001, road-registered as HKV 455, was the first prototype built. It was also
300-551: A matching numbers left-hand-drive alloy-bodied roadster – one of only 184 – for $ 396,000 (£302,566). This marks the highest price achieved for an XK120 at auction thus far. The first 242 production XK120s, hand-built with aluminium bodies on ash framing, were constructed between late 1948 and early 1950. To meet demand, and beginning with the 1950 model year, all subsequent XK120s were mass-produced with pressed-steel bodies. Aluminium doors, bonnet , and boot lid were retained. The DHC and FHC versions, more luxuriously appointed than

The flat glass two-piece windscreen was set in a steel frame that was integrated with the body and painted the same colour. Dashboards and door-caps in both the DHC and the closed coupé (FHC) were wood-veneered, whereas the open cars were leather-trimmed. All models had removable spats ("fender skirts" in America) covering
420-503: A passenger-side tonneau cover in place. In 1950 and 1951, at Autodrome de Linas-Montlhéry , a banked oval track in France, open XK120s averaged over 100 mph (160 km/h) for 24 hours and over 130 mph (210 km/h) for an hour. In 1952 a fixed-head coupé took numerous world records for speed and distance when it averaged 100 mph for a week. XK120s were also highly successful in racing and rallying. In 2016, Bonhams sold
480-399: A pressed-steel chassis, a gated 4-speed transmission, pushrod-actuated overhead inlet valves , a honeycomb radiator, low-tension magneto ignition , a long wheelbase, a low center of mass and a very effective suspension system. The overall result was a "safe and well-balanced machine" with a higher performance than any other contemporary production car. At the 1903 Gordon Bennett Cup ,
540-427: A production Simplex 60 hp was entered only due to a specially-built 90 hp racing car being destroyed in a fire; the 60 hp famously went on to win the race. The 1910 Austro-Daimler 27/80 is another early sports car which had success in motor racing. The 27/80 was designed by Ferdinand Porsche , who drove the car to victory in the 1910 Prince Henry Tour motor race. The Vauxhall and Austro-Daimler —like
600-470: A standard 8:1 compression ratio developed 160 bhp (119 kW). Most of the early cars were exported; a 7:1 low-compression version, with commensurately reduced performance, was reserved for the UK market, where the post-war austerity measures then in force restricted buyers to 70 octane "Pool petrol". The Jaguar factory's access to 80 octane fuel allowed it to provide cars with the higher compression ratio to
660-452: Is an iconic sports car of the early 1960s, due to its attractive styling and claimed top speed of 241 km/h (150 mph). The E-type was produced for 14 years and was initially powered by a six-cylinder engine, followed by a V12 engine for the final generation. In 1962, the MG B introduced a new era of affordable lightweight four-cylinder roadsters. The MG B used a unibody construction and

The location of the engine and driven wheels significantly influence the handling characteristics of a car and are therefore crucial in the design of a sports car. Traditionally, most sports cars have used rear-wheel drive with the engine either located at the front ( FR layout ) or in
780-520: The Audi RS 2 Avant . Ford Europe withdrew from the sports car market at the end of 1986 when the Capri was discontinued after a production run of nearly two decades. There was no direct successor, as Ford was concentrating on higher-performance versions of its hatchback and saloon models at the time. In 1989, a new generation of Lotus Elan roadster was released which used a front-wheel drive layout,
840-541: The BMW 303 , Citroën Traction Avant and Fiat 508 — offered similar handling and comfort to the more expensive sports cars. Powerful, reliable, and economical (although softly suspended) American saloons began to be imported to Europe in significant numbers. Sports car ownership was increased through models such as the Austin 7 and Wolseley Hornet six , however many of these sports cars did not offer any performance upgrades over
900-623: The Bentley Speed Six (1928-1930), with the former famously described by Bugatti's founder as "the fastest lorry in the world". Between the Great Depression and the World War II the pre-war era was a period of decline in importance for sports car manufacturers, although the period was not devoid of advances, for example streamlining . Cheap, light-weight family sedans with independent front suspension— such as
960-520: The Jensen FF became the first sports car to use all-wheel drive . The Ford Capri is a 2+2 coupe that was produced from 1968 to 1986 and intended to be a smaller European equivalent of the Ford Mustang. A main rival to the Capri was Opel Manta , which was produced from 1970 to 1988. The 1973-1978 Lancia Stratos was a mid-engined two-seat coupe that was powered by a Ferrari V6 engine. This

In the United Kingdom, early recorded usage of the "sports car" was in The Times newspaper in 1919. The first known use of the term in the United States
1080-403: The 1905 Isotta Fraschini Tipo D, the 1906 Rolls-Royce Silver Ghost , the 1908 Delage , the 1910 Bugatti Type 13 , and the 1912 DFP 12/15 . Early motor racing events included the 1903 Paris–Madrid race , the 1905-1907 Herkomer Trophy, the 1908-1911 Prince Henry Tour and the 1911–present Monte Carlo Rally . The Prince Henry Tours (which were similar to modern car rallies) were among
1140-495: The 1921 Coppa Florio . Another approach— such as that used by Morris Garages— was to convert touring cars into sports cars. The first 24 Hours of Le Mans race for sports cars was held in 1923, although the two-seat sports cars only competed in the smallest class, with the majority of cars entered being four-seat fast touring cars. "This race, together with the Tourist Trophy Series of Races , organised after
1200-404: The 1948 Ferrari 166 S . A new concept altogether was the modern Gran Turismo class from Italy, which was in effect unknown before the war: sustained high-speed motoring from relatively modest engine size and compact closed or berlinetta coachwork. The 1947 Maserati A6 1500 two-seat berlinetta was the first production model from Maserati. In Germany, the motor industry was devastated by

When tested, it had the 8:1 compression ratio, was fitted with an aerodynamic undertray, and ran with hood and sidescreens in place. The magazine reported a top speed of 124.6 mph (200.5 km/h), acceleration from 0–60 mph (97 km/h) in 10.0 seconds and fuel consumption of 19.8 miles per imperial gallon (14.3 L/100 km; 16.5 mpg ‑US ). The car as tested cost £1263 including taxes. The XK120 M for US market accelerated from 0–60 mph (97 km/h) in 8.7 seconds, top speed

In the 1970s, turbocharging began to be adopted by sports cars, such as the BMW 2002 Turbo in 1973, the first Porsche 911 Turbo in 1975, and the Saab 99 Turbo in 1978. Turbocharging became increasingly popular in the 1980s, from relatively affordable coupes such as
1380-452: The 1980–1986 Renault Fuego and 1992–1996 Rover 220 Coupé Turbo , to expensive supercars such as the 1984-1987 Ferrari 288 GTO and 1987-1992 Ferrari F40 . In the late 1980s and early 1990s, several manufacturers developed supercars that competed for production car top speed records . These cars included the 1986–1993 Porsche 959 , 1991–1995 Bugatti EB 110 , 1992–1994 Jaguar XJ220 and 1993–998 McLaren F1 . The 1980-1995 Audi Quattro
1440-506: The 1990s, all-wheel drive has become more common in sports cars. All-wheel drive offers better acceleration and favorable handling characteristics (especially in slippery conditions), but is often heavier and more mechanically complex than traditional layouts. Examples of all-wheel drive sports cars are the Lamborghini Huracan , Bugatti Veyron , and Nissan GT-R . Rear engine layouts are not typical for sports cars, with
1500-468: The Mercedes Simplex 60 hp— were production fast touring cars. The 1912 Hispano-Suiza Alfonso XIII is also considered one of the earliest sports cars, as it was a "purpose built, high performance, two-seater production automobile". The model was named after King Alfonso XIII of Spain , a patron of the car's chief designer and an enthusiast for the marque. Other early sports cars include
1560-555: The UK market was cancelled prior to production. On 30 May 1949, on the empty Ostend-Jabbeke motorway in Belgium, a prototype XK120 timed by the officials of the Royal Automobile Club of Belgium achieved an average of runs in opposing directions of 132.6 mph (213.4 km/h) with the windscreen replaced by just one small aero screen and a catalogued alternative top gear ratio, and 135 mph (217 km/h) with

Details of the model were included in an "Advance Particulars" brochure for the XK but Jaguar's managers were dissatisfied with the engine and the project was cancelled prior to production. Sports car A sports car is a type of car that is designed with an emphasis on dynamic performance, such as handling , acceleration, top speed, the thrill of driving, and racing capability. Sports cars originated in Europe in
1740-479: The car appeared during the next year or two, all conforming to the same basic design and earning for themselves a reputation second to none for fast and reliable travel. The 60-h.p. cars were announced late in 1902. The cars were possessed of a very real performance superior to anything else which could be bought at the time... and the model achieved an almost invincible position among the fast cars of its day. The Sports Car: Development and Design The basis for
1800-584: The constantly exposed open cars, had wind-up windows and wood veneers on the dashboard and interior door caps. The XK120’s steel chassis was mostly copied from the Jaguar Mark V , using many of the same parts. The dual overhead-cam 3.4 L straight-6 XK engine was highly advanced for a mass-produced unit of the time, featuring a high-temperature, high-strength aluminum alloy cylinder head , hemispherical combustion chambers , inclined valves, and twin side-draft SU carburetors . Using 80 octane fuel

Following the halt in sports car production caused by World War I , Europe returned to manufacturing automobiles from around 1920. It was around this time that the term 'Sports Car' began to appear in the motor catalogues, although

1920-489: The early 1910s and are currently produced by many manufacturers around the world. Definitions of sports cars often relate to how the car design is optimised for dynamic performance, without any specific minimum requirements; both a Triumph Spitfire and Ferrari 488 Pista can be considered sports cars, despite vastly different levels of performance. Broader definitions of sports cars include cars "in which performance takes precedence over carrying capacity", or that emphasise
1980-400: The early 1920s, the cost to produce a racing car was not significantly higher than a road car, therefore several manufacturers used the design from the current year's racing car for the next year's sports car. For example, the 1921 Ballot 2LS based on the racing car that finished third at the 1921 French Grand Prix. The Benz 28/95PS was also a successful racing car, with victories including
2040-463: The exact origin of the name is not known. The decade that followed became known as the vintage era and featured rapid technical advances over the preceding Brass Era cars . Engine performance benefited from the abandonment of " tax horsepower " (where vehicles were taxed based on bore and number of cylinders, rather than actual power output) and the introduction of leaded fuel , which increased power by allowing for higher compression ratios . In

The doors had no external handles; they were opened by an interior pull-cord , accessed through a flap in the sidescreens when the weather equipment was in place. The windscreen could be removed for aeroscreens to be fitted. The drophead coupé (DHC) had
2160-472: The first supercars . Other significant European models of the 1960s and 1970s which might be considered supercars today are the Ferrari 250 GTO (1962-1964), Ferrari 250 GT Lusso (1963-1964), Ferrari 275 GTB/4 (1966-1968), Maserati Ghibli (1967-1973), Ferrari Daytona (1968-1973), Dino 246 (1969-1974), De Tomaso Pantera (1971-1993), Ferrari 308 GTB (1975-1980) and BMW M1 (1978-1981).

Two cars from the Vintage Era that would influence sports cars for many years were the Austin Seven and MG M-type "Midget". Successful sports cars from Bentley during this era were the Bentley 3 Litre (1921-1929) and

Examples of MR layout sports cars are the Ferrari 488 , Ford GT , and Toyota MR2 . To avoid a front-heavy weight distribution , many FR layout sports cars are designed so that the engine is located further back in the engine bay, as close to the firewall as possible. Since
2460-544: The most common layout for sports cars was a roadster (a two-seat car without a fixed roof). However, there are also several examples of early sports cars with four seats. Sports cars are not usually intended to transport more than two adult occupants regularly, so most modern sports cars are generally two-seat or 2+2 layout (two smaller rear seats for children or occasional adult use). Larger cars with more spacious rear-seat accommodation are usually considered sports sedans rather than sports cars. The 1993-1998 McLaren F1

2520-455: The name referred to the aluminium car's 120 miles per hour (190 km/h) top speed (faster with the windscreen removed), which made it the world's fastest production car at the time of its launch. In 1949 the first production car, chassis number 670003, was delivered to Clark Gable . The XK120 was ultimately available in three body styles, all two-seaters and available either as Left (LHD) or Right Hand Drive (RHD): an open 2-seater described in
2580-809: The notable exception of the Porsche 911 . The front-wheel drive layout with the engine at the front ( FF layout ) is generally the most common for cars, but it is not as common among traditional sports cars. Nonetheless, the FF layout is used by sport compacts and hot hatches such as the Mazdaspeed3 . Sports cars with an FF layout include the Fiat Barchetta , Saab Sonett , or Opel Tigra . The ancestor of all high-performance cars had its origin in Germany. The 28-h.p. Cannstatt-Daimler racing car of 1899

The XK engine's basic design by William Heynes, later modified into 3.8 and 4.2-litre versions, survived until 1992. All XK120s had independent Heynes designed torsion bar front suspension , semi-elliptic leaf springs at the rear, recirculating ball steering, telescopically adjustable steering column, and all-round 12-inch drum brakes which were prone to fade . Some cars were fitted with Alfin (ALuminium FINned) brake drums to help overcome
2760-444: The production cars except that the straight outer pillars of its windscreen were curved on the production version. The sports car caused a sensation, which persuaded Jaguar founder and Chairman William Lyons to put it into production. Beginning in 1948, the first 242 cars were wood-framed open 2-seater bodies with aluminium panels. Production switched to the 1cwt or 112 lb (51 kg) heavier all-steel in early 1950. The "120" in
2820-423: The production of two-seat sports cars being limited to smaller manufacturers such as Aston-Martin (350 Astons built from 1921 to 1939) and Frazer-Nash (323 cars built from 1924 to 1939). Then by the late 1920s, the cost of producing racing cars (especially Grand Prix cars) escalated, causing more manufacturers to produce cars for the growing sports car market instead. Significant manufacturers of sports cars in

On cars fitted with optional centre-lock wire wheels (available from 1951), the spats were omitted as they gave insufficient clearance for the chromed, two-eared Rudge-Whitworth knockoff hubs . Chromium-plated wire wheels were optional from 1953. Factory standard 6.00 × 16-inch cross ply tyres were fitted on 16 × 5K solid wheels (Pre–1951), with 185VR16 Pirelli Cinturato radial tyres available as
2940-558: The sporting events of the period, bringing renown to successful entrants. The Prince Henry Tours started the evolution of reasonably large and technically advanced production sports cars. In England, the development of sporting cars was inhibited by the Motor Car Act 1903 , which imposed a speed limit of 20 mph (32 km/h) on all public roads. This led to the 1907 opening of the Brooklands motor circuit , which inspired
3000-408: The sports car is traced to the early 20th century touring cars and roadsters , and the term 'sports car' would not be coined until after World War One. A car considered to be "a sports-car years ahead of its time" is the 1903 Mercedes Simplex 60 hp , described at the time as a fast touring car and designed by Wilhelm Maybach and Paul Daimler . The Mercedes included pioneering features such as
3060-476: The sports car, but also the most important and diverse technical developments [and] very rapid and genuine improvement in the qualities of every modern production car; assisted by new design and manufacturing techniques a consistently higher level of handling properties has been achieved." In Italy, a small but wealthy market segment allowed for the manufacture of a limited number of high-performance models directly allied to contemporary Grand Prix machines, such as

#17327720877953120-478: The war, but a small number of manufacturers returned it to prominence. In 1948, the Porsche 356 was released as the debut model from Porsche. The significance of the Porsche 356 and its successors was described in 1957 as "future historians must see them as among the most important of mid-century production cars". The 1954 Mercedes-Benz 300 SL is another significant car from this era. The 1961 Jaguar E-Type

XK120s were active in racing and rallying: In 1950 Jaguar allocated six alloy-bodied XK120s to drivers Leslie Johnson, Peter Walker, Nick Haines, Clemente Biondetti , Ian Appleyard and Tommy Wisdom. A 2-litre four-cylinder version of the twin cam XK engine was to have powered an XK100 variant of

The BMW M3 was released in 1986 and has been produced for every generation since. The 1993-1996 Mercedes-Benz W124 E36 AMG was the mass-produced AMG model. Audi's equivalent division, called "RS", was launched in 1994 with

The Lancia Montecarlo was produced from 1975 to 1981 and is a mid-engine two-seater, available as a coupé or a targa-top. It was sold as Lancia Scorpion in the USA. Its racing variant, Montecarlo Turbo, won the 1979 World Championship for Makes in its division and overall for 1980 World Championship for Makes and 1981 World Endurance Championship for Makes . Montecarlo also won

The T57 was successful in sports car races, including winning the 1937 24 Hours of Le Mans and 1939 24 Hours of Le Mans . Another successful Bugatti sports car was the Bugatti Type 55 (1932-1935), which was based on the Type 51 Grand Prix racing car. The decade following the Second World War saw an "immense growth of interest in
3420-485: Was in 1928. Sports cars started to become popular during the 1920s. The term initially described two-seat roadsters (cars without a fixed roof), however, since the 1970s the term has also been used for cars with a fixed roof (which were previously considered grand tourers ). Attributing the definition of 'sports car' to any particular model can be controversial or the subject of debate among enthusiasts. Authors and experts have often contributed their ideas to capture
3480-694: Was produced until 1980. Other successful lightweight roadsters include the Triumph Spitfire (1962-1980) and the Alfa Romeo Spider (1966-1993). The Fiat X1/9 (1972-1989) was unusual for its use of a mid-engine design in an affordable roadster model. A late entrant to the affordable roadster market was the 1975 Triumph TR7 , however by the late 1970s the demand for this style of car was in decline, resulting in production ceasing in 1982. The original Lotus Elan (1962-1975) two-seat coupe and roadster models are an early commercial success for
3540-675: Was released in 1964 and has remained in production since. The 911 is notable for its use of the uncommon rear-engine design and the use of a flat-six engine . Another successful rear-engine sports car was the original Alpine A110 (1961-1977), which was a successful rally car during the Group 4 era. In 1965, the BMW New Class Coupes were released, leading to the BMW 6 Series which remains in production to this day. The Lamborghini Miura (1966) and Alfa Romeo 33 Stradale (1967) mid-engined high-performance cars are often cited as

Many of its features, such as a honeycomb radiator and gate gear change, were continued on the much improved version which Paul Daimler designed in 1899-1900. This was of course the famous Mercedes. It also laid down standards of chassis design which were to be followed, almost unthinkingly, for the next thirty years. Several variants of
