The Lysholm-type twin-screw supercharger rotates at a maximum of 23,000 rpm and produces 0.9 bar (13 psi) of boost. The compressed air is then cooled via two intercoolers . The engine generates a maximum power output of 626 PS (460 kW; 617 hp) at 6,500 rpm and maximum torque of 780 N⋅m (575 lbf⋅ft) between 3,250 and 5,000 rpm. McLaren took
465-695: A "much abused and confused term") are typically more "crude" compared to "sophisticated Grand Touring machinery". However, the popularity of using GT for marketing purposes has meant that it has become a "much misused term, eventually signifying no more than a slightly tuned version of a family car with trendy wheels and a go-faster stripe on the side". Historically, most GTs have been front-engined with rear-wheel drive , offering more cabin space than mid-mounted engine layouts. Softer suspensions, greater storage, and more luxurious appointments add to their appeal. The GT abbreviation—and variations thereof—are often used as model names. However, some cars with GT in
558-601: A 100 mph car. Lancia chose the Gran Turismo name for its new model and the suggestion could only have come from Vittorio Jano himself, for had he not been responsible for the original 1750 Alfa Romeo of the same name back in 1929? Four semi-ufficiali works B20 GTs, together with a number of privateer entrants, were sent to the Mille Miglia in April 1951, where the factory Bracco / Maglioli car finished second overall, behind only
651-501: A 5.0-litre supercharged AMG V8 engine able to generate a power output of 565 PS (416 kW; 557 hp) and 720 N⋅m (531 lb⋅ft) of torque at 4,000 rpm, mated to a 5-speed automatic gearbox with Touchshift control. Wanting to bring the concept to production following its positive reception, Mercedes joined forces with their Formula One partner, McLaren, thus creating the Mercedes-Benz SLR McLaren. Mercedes did
744-562: A 6C Alfa Romeo and Maserati in 1948, along with the Fiat 1100 S coupé with its rear accommodation for children. The original Aurelia had been under-powered and, in 1951, the V6 was enlarged to 1991 cc, which was also extended to the coupé, though in 75 rather than 70 bhp form as the B20 was developed as a sporting model in its own right. In addition the B20 had a shorter wheelbase and a higher rear axle ratio, making it
837-460: A Ferrari sports racer of twice the engine capacity. Lancia Aurelias swept the GT 2.0 Liter division. In June 1951, Bracco was partnered with the "father of GT racing" himself, Johnny Lurani , to race a B20 GT at Le Mans, where they were victorious in the 2.0 liter sportscar division, placing a very creditable 12th overall. A 1–2 finish at the famous Coppa d'Oro delle Dolomiti, among other victories including
930-536: A GT car", was winner of the Vetture Chiuse category at the 1931 Mille Miglia. An improved and supercharged version, the 6C 1750 GTC Gran Turismo Compressore , won the Vetture a Guida Interna category of the 1932 Mille Miglia. The Alfa Romeo 6C 1750 was designed by Vittorio Jano, who would later be instrumental in the design of the 1951 Lancia Aurelia B20 GT. From the basic Fiat 508 Balilla touring chassis came

6231-491: The original concept car designed by Mercedes and moved the engine 1 metre (39.4 in) behind the front bumper, around 50 centimetres (19.7 in) behind the front axle. They also optimised the design of the centre firewall. The SLR uses the AMG SPEEDSHIFT R five-speed automatic transmission with three manual modes. For durability, Mercedes selected a five-speed transmission rather than their seven-speed transmission which
6324-596: The outstanding design of its Pinin Farina coachwork , and is credited with greatly influencing the style of subsequent berlinetta or fastback gran turismo coupés. A Cisitalia 202 "GT" is exhibited at the Museum of Modern Art in New York City . The Maserati A6 1500 won the 1500 cc class at the 1949 Coppa-Europa. It was driven by Franco Bordoni , former fighter ace of the Regia Aeronautica who had debuted as
6417-462: The previous models, available with either the Colombo or Lampredi versions of the 250 V12 engine, coil spring front suspension, an improved sports gearbox (four speeds) with Porsche synchromesh , large drum brakes and luxurious outfitting. A few appeared in motorsports but did not initially threaten the international Mercedes-Benz 300 SL and Porsche 356 competition. In the Mille Miglia of 1956
6510-633: The racing division of Alfa Romeo from 1929 until 1938, parted ways from Alfa Romeo in 1939: Enzo Ferrari's first car (itself an Etceterini) the Fiat-based Auto Avio Costruzioni 815 racing sports car , debuted at the 1940 Mille Miglia. Two were produced. The first car constructed in Ferrari's name, the V12 125 S , also a racing sports car, debuted in 1947 at the Piacenza racing circuit. Again, only two were produced, but they rapidly evolved into
6603-417: The rear. The engine is sharply inclined to the near-side in the interests of a low bonnet-line, and with Bosch fuel injection produces 240 b.h.p. at 6,000 r.p.m. Claimed maximum speed is in excess of 160 m.p.h. and although the car is by no means small, dry weight has been kept to 23 cwt . The depth of the multi-tubular frame prevents the use of conventional side-hinged doors and these cars are fitted with
6696-502: The roof-hinged "gull-wing" doors which characterize an exceedingly handsome and practical car. An open touring version is available. In competition the "300SL" has become a powerful contender, and abetted by the success of the Grand Prix cars [and " 300 SLR "] has captured a substantial portion of the export market." The 250GT Ferrari must surely represent the ultimate in modern high-speed sporting travel, or GT competition, and holds today
6789-409: The roof. For lightness, Zagato pioneered the use of Perspex and of aerodynamics, with trademark forms such as the split or stub tail. Indeed, Elio would take prototypes out on the autostrada covered in wool tufts in order to test air flow over the body. The 8V Otto Vu earned its name courtesy of its high-performance V8 engine (Ford having already trademarked "V8"). The German automotive industry
6882-440: The styling on the car while McLaren was fully responsible for everything else, from the design and the engineering to the manufacture and the testing of each car at the production line. The production version of the car was unveiled to the general public on 17 November 2003 having some major design adjustments in respect of the initial design. In order to give the car the performance that Mercedes wanted, McLaren had to radically alter
6975-453: The successful Alfa Romeo 6C GT/GTC coupés , competed in the Mille Miglia endurance race and were significant among Weymann and Superleggera enclosed sporting cars appearing in the 1930s. They featured tuned Fiat engine and chassis, and bespoke carrozzeria , in common with the landmark post-war Cisitalia 202 SC , and are among the first small-displacement gran turismos . The first recognised motor race specifically for gran turismo cars
7068-504: The supply. In November 2016, it was reported that a 1962 Ferrari 250 GTO was being offered for public sale—normally brokers negotiate deals between extremely wealthy collectors "behind closed doors". GTOs had previously been auctioned in 1990 and 2014. The 2017 sale was expected to reach US$ 56,000,000.00, the particular GTO concerned (the second of just thirty-six ever made) thus set to become the world's most expensive car. The Italian Mille Miglia thousand-mile race, held from 1927 to 1957,
7161-678: The suspension, with a stiffer damper setup and 10 mm (0.39 in) lower ride height introduced for improved handling. Larger 390 mm (15.4 in) diameter front brakes and a revised front air dam and rear diffuser were fitted. Other exterior changes include red "722" badging, harking back to the original 722 racer, black tinted tail lights and headlamps. The interior has carbon fibre trim and black leather upholstery combined with Alcantara . The SLR 722 can accelerate from 0 to 100 km/h (62 mph) in 3.6 seconds, 0 to 200 km/h (124 mph) in 10.2 seconds and 300 km/h (186 mph) in 27.6 seconds, and can attain
7254-474: The transformation. Production was limited to just 21 units. The 722 GT could accelerate from 0–97 km/h (0–60 mph) in 3.3 seconds and could attain a top speed of 315 km/h (196 mph), which is less than the standard SLR due to added aerodynamic drag. The SLR McLaren 722 GT was available to the North American market exclusively through their dealerships by Renntech . The SLR "Crown Edition"
7347-609: Was 170 bhp from the 2600cc Gioacchino Colombo-designed 'short-block' V12 engine , evolved from the earlier Ferrari 166 (2000cc) and 195 (2300cc). All versions came with the standard Ferrari five-speed non-synchromesh gearbox and hydraulic drum brakes. All 1951 Ferraris shared a double tube frame chassis design evolved from the 166. Double-wishbone front suspension with transverse leaf spring , and live rear axle with semi-elliptic leaf springs and radius rods were employed. The Ferrari 212 Export (212 MM) gran turismo berlinetta (chassis No. 0070M) debuted in first-place overall at
7440-435: Was a homage to the Mercedes-Benz 300 SLR which served as the car's inspiration. The car was offered in coupé , roadster and speedster bodystyles, with the latter being a limited edition model. At the 1999 North American International Auto Show , Mercedes-Benz presented their Vision SLR concept, inspired both by the Mercedes-Benz 300 SLR Uhlenhaut Coupé of 1955, which was a modified Mercedes-Benz W196S race car, and
7533-503: Was beneficial for the Mille Miglia road race held in Italy's often wintry north. The first car to be named " gran turismo " was the 1929 Alfa Romeo 6C 1750 Gran Turismo , a sporting dual-purpose road/race chassis and engine specification that was available with a wide variety of body styles or carrozzeria . The influential Weymann fabric-bodied berlinetta version by Carrozzeria Touring, "an early example of what we generally perceive to be
7626-412: Was central to the evolution of the gran turismo concept. The event was one of the most important on the Italian motor-sport calendar and could attract up to five million spectators. Winning drivers such as Tazio Nuvolari , Rudolf Caracciola , and Stirling Moss ; and manufacturers such as Alfa Romeo, BMW , Ferrari and Porsche would become household names. According to Enzo Ferrari: In my opinion,
7719-607: Was commissioned by the King of Bahrain as gifts for fellow Arab royals. This run of 10 cars was upgraded with 722-specification parts, including the uprated and modified engine, carbon fibre aerodynamic parts, stiffer dampers and 19-inch lightweight alloy wheels. Named after the British racing driver of the same name , the SLR Stirling Moss is a limited edition variant unveiled at the 2009 North American International Auto Show , which uses
7812-407: Was devastated by the second World War, but in the post-war period a small number of firms brought it to prominence again. The emergence of the classic Porsche 356 is covered in the accompanying sports car article. In 1957 author John Stanford wrote: "The post-war Mercedes sports cars are in a way even more remarkable than those of Porsche . The firm was particularly badly hit by the war and it
7905-409: Was employed, and the camshaft valve timing was only slightly less than the full-race Testa Rossas . G.T. power was up to 267 b.h.p. at 7,000 r.p.m. (240 b.h.p at 6,800 rpm for road versions). Experiments were conducted with Dunlop disc brakes, which were adopted in 1960, along with an even shorter wheelbase for competizione versions. In 1962, the definitive competition gran turismo was unveiled,
7998-485: Was impressed by the dominant performance at the Mille Miglia in 1940, by a carrozzeria touring-bodied BMW 328 coupé, winning the event at over 100 mph average speed, driven by Fritz Huschke von Hanstein and Walter Bäumer : The BMW team included a splendid aerodynamic Berlinetta , wind tunnel designed by German specialists, that was extremely fast at 135 mph... I couldn't believe the speeds these BMWs were capable of. Italy's national governing body of motorsport
8091-401: Was more complex and used more parts. The car uses carbon-fibre reinforced plastic (CFRP) construction in an attempt to keep the weight low. Despite CFRP materials, the total curb weight is 1,750 kg (3,858 lb). The SLR could attain a top speed of 207 mph (333 km/h). Road And Track tested the car in their July 2005 Road Test and reached 97 km/h (60 mph) from
8184-465: Was offered for only 25 cars. The SLR by MSO was announced in 2021 by McLaren Special Operations. The project was said to be inspired by collectors, who often owned 3 or more SLR's, asking to send their cars back to MSO to receive upgrades or spec changes. In response to this, MSO launched the SLR by MSO program, allowing owners to upgrade their cars to the latest MSO technology, and to choose their own specs. The SLR by MSO upgrade cost £131,500 and features
8277-426: Was several years before anything but a nominal production of cars could be undertaken. In 1951 appeared the "300" , a luxurious and fast touring car with a single-camshaft six-cylinder engine of 2996 c.c. and chassis derived from the pre-war cars with swing-axle rear suspension. The "300S" was a three-carburetor edition, but in 1952 great interest was aroused by the almost invincible performance in sports-car racing of
8370-576: Was the Commissione Sportiva Automobilistica Italiana (CSAI). Count Giovanni Lurani Cernuschi (popularly known as Johnny Lurani) was a key commissioner. He was also a senior member of the world governing body, the Fédération Internationale de l'Automobile (FIA). Lurani was instrumental in designing the regulations for the Italian 1937 Turismo Nazionale championship, whereby production vehicles approved by
8463-472: Was the 1949 Coppa Inter-Europa held at Monza . It was initially hoped by Italian motor industry observers that the small and struggling Italian sports and racing car manufacturer, Cisitalia, would find in the 1949 Coppa Inter-Europa regulations (initially called Turismo Veloce or Fast Touring) a category for its Cisitalia Tipo 202 SC —the road-going production coupé version of Cisitalia's single-seat D46 racing car and two-seat 202 open sports car. However,
8556-424: Was the road/race Ferrari 212 . Twenty-seven short-wheelbase competition versions called Export, some with increasingly popular gran turismo -style berlinetta coupé coachwork, were produced for enthusiasts (Ferrari called the first example 212 MM ) while the road version was called Inter . The Ferrari 212 Export featured long-range fuel tanks, high compression pistons and triple Weber 32 DCF carburettors ; power
8649-491: Was unveiled to an enthusiastic motoring public. Here, finally, according to historians Jonathan Wood and Sam Dawson, was a fully realized production GT car, representing the starting point of the definitive grand tourer: This outwardly conventional saloon bristled with innovation and ingenuity, in which the masterly hand of Vittorio Jano is apparent. In the B20 are elements of the Cistalia of 1947, coupés which Pinin undertook on
