The GT6 MKI is a 6-cylinder sports car which was built by Triumph. Production ran from 1966 to 1968 .The GT6 fixed head coupe that was based on the Triumph Spitfire .

History 

The GT6 is the result of a happy marriage between the little Spitfire andthe 2000 Saloon, but in some ways it is quite different from both. The new coupé has taken the body used by the official works team or the 1964 and 1965 Le Mans 24 Hours (the power bulge on the bonnet is one difference from the Spitfire) and also the chassis and suitably strengthened suspension. The 2000 engine has been taken over, but, with the compression ratio increased to 9.5, it now develops 95 hp DIN at 5,000 rpm. Since this car weighs only 1,793 pounds (913 kg) the power-weight ratio is extremely favourable for a car of this category and results in formidable acceleration powers (from O to 50 miles per hour in under 7.8 seconds), Both for this reason and because the maximum torque is very high (117 1b ft. 16.2 kgm at 3,000 rpm) there is no need. even in town traffic, to change gear
too frequently.The suspension is independent all round, with wishbones, coil springs,like the co-axial telescopic dampers and anti-roll bar on the front, and— swinging semi-axles with a transverse semi-elliptic leafspring and Spitfire longitudinal radius rods on the rear.

With the Spitfire, Triumph introduced an affordable sports car in 1962. At the time, the competitor MG had a coupe on offer from the MGB, which sold well. Triumph therefore commissioned the Italian designer Giovanni Michelotti to also design a coupé based on the Spitfire The new body was a sleek fastback with an opening rear hatch .It was a two-seater, but a little extra back seat could be obtained if needed, and it was big enough for small kids The basic price new was £ 985 inc in the UK and just over $ 2,000 in the US . Due to the higher weight, however, the performance of the Spitfire engine proved to be insufficient in this car, which is why the 2-litre six-cylinder engine from the Triumph Vitesse was installed in the new Spitfire coupe.

 The Triumph GT6 was a new car that was released in 1966. With its rear hatchback. The GT6 was well equipped. Inside that as the spifire with addition to the wooden dashboard with four instruments, it had a two-speed windshield wiper, a two-speed heater fan, a padded steering wheel and bucket seats as standard. There is
also a collapsible safety device for the steering column in case of accidents. The polished wood facia includes trip arid total mileage recorder, rev counter, temperature gauge and fuel gauge. There is no oil gauge, but a warning light comes on when the pressure falls too tow. finger-tip stalks from the steering column control indicators, overdrive and lights. The courtesy light is operated by the rear door as well as the two side doors. 

The chassis as of the Spifire was double backbone, channel section with outriggers. The swing-axle system adopted from the Spitfire and the Triumph Herald small saloon.The Mk.1 model was 3717 mm long and 1450 mm wide.Front suspension was  independent, wishbones, coil springs, anti-roll bar, and telescopic dampers the 
rear independent, swinging semi-axles, transverse leafspring upper arms,swinging longitudinal trailing arms,and  telescopic dampers. 

Powered by 2 Stromberg 1-50 CD horizontal carburettors , the old 6-cylinder delivered 95 hp , thanks to the weight of only 864 kg, to undermine the original set-up (identical to that of the Spitfire ).  Due to the higher weight, however, the performance of the Spitfire engine proved to be insufficient in this car, which is why the 2-litre six-cylinder engine from the Triumph Vitesse was installed in the new coupe.The enlarged 6-cylinder engine demanded a redesigned bonnet top with a power bulge, and the doors were equipped with opening quarter light windows and squared-off glass in the top rear corner, and the family resemblance to the Spitfire Mk II was evident.The 6-cylinder engine was adjusted to produce 95 horsepower (71 kW) at 5000 rpm and 117 pound-feet of torque (159 Nm) at 3000 rpm.

PERFORMANCE

• engine capacity 121.92 cu in, 1,998 cu cm
• fuel consumption 25.7 mlimp gal, 21.4 ml US gal
• max speed 107 mph, 172.3 km/h
• max power (DIN): 95 hp at 5,000 rpm
• max torque (DIN): 117 1b ft, 16.1 kg m at 3,000 rpm
• max engine rpm: 6,000
• specific power: 47.5 hp/l
• power-weight ratio: 19 lb/hp, 8.6 kg/hp
• acceleration: standing 1/4 mile 17.7 sec, 0—50 mph (0— 80 km/h) 7.8 sec

The increased power necessitated certain changes to the Spitfire mechanics; the radiator was new and mounted further forward in the car and the gearbox was the stronger unit from the Vitesse, with optional overdrive. Front springs were uprated to cope with the extra weight from the new engine. The overall vehicle weight unladed was 1,904 lb (864 kg). The interior of the GT6 was well equipped; a wooden dashboard housed a full complement of instruments, with carpets and heater included as standard.

The new car had some very strong selling points. The new engine provided a 106 mph (171 km/h) top speed and 0–60 mph in 12 seconds, better than the MGB GTs rather harsh 4-cylinder engine B series engine. Fuel economy was very reasonable for the period at 20mpg, and the interior well up to the competition. The only major criticism was of its rear suspension; the GT6 inherited the swing-axle system from the Spitfire, which in turn was copied from the Herald small saloon. In the saloon it was tolerated, in the little Spitfire it was not liked and in the powerful GT6 it was heavily criticised. Triumph had done nothing to improve the system for the GT6 and the tendency to break away if the driver lifted off the power mid-corner was not helped at all by the increased weight at the front of the car. The handling was most bitterly criticised in the USA, an important export market for Triumph, where they were traditionally very strong. Similar criticism was being levelled at the Vitesse saloon, which shared the GT6's engine and its handling problems.

The Triumph Vitesse Mk1 is a sports car built by Standard-Triumph from May 1962 to July 1968.

History

The Triumph Vitesse is a compact six-cylinder car built by Standard-Triumph. The car was styled by Giovanni Michelotti, and was available in saloon and convertible variants.

The Vitesse name was first used by Austin on their 1914–16 Austin 20 and 30 hp models, then first used by Triumph between 1936 and 1938. The name remained unused until 1982, when Rover used it on their SD1 until 1986, and later on the final Rover models for ten years from 1988 to 1998.

The Triumph Vitesse 6 was introduced on May 25, 1962. It was the high-performance variant of the Herald small two-door sedan. The Herald was introduced on April 22, 1959. Its shape also came from Michelotti. In the early 1960s, Triumph considered building a small six-cylinder sports sedan based on it. Michelotti was in turn tasked with the styling and presented a car that used almost all of the Herald's body panels and featured a new front end. The front of the vehicle with its offset twin 4-headlights was called "Chinese Eye".

Standard-Triumph incorporated the familiar 1,596 cc straight-six engine from the Standard Vanguard Six, but with a smaller bore of 66.75mm instead of the Vanguard's 74.7mm and twin Solex B32PIH downdraft carburettors. These carburettors were replaced with B321H carburettors soon after the car's introduction as the accelerator pump proved to be a problem. Close inspection reveals a seam on the cylinder block between the third and fourth cylinders, indicating the beginnings of this engine design as the 803-cc block of the 1953 Standard Eight. The manual gearbox was strengthened and with an overdrive offered by Laycock-de-Normanville, D-type. Disc brakes at the front and more powerful drum brakes at the rear were offered as standard, and the Herald's fuel tank was enlarged while retaining the spare cock of the smaller tank. Due to the higher weight of the six-cylinder engine, the front wheel suspension was equipped with stronger coil springs, on the rear axle the Herald system was equipped with a swing axle and transverse leaf spring, but soon proved to be unsuitable for the more powerful Vitesse. The chassis essentially corresponded to that of the Herald. A sedan and a convertible were available; a coup that was also designed never made it to series production. A handful of station wagons were also built on special customer request at Standard-Triumph's Park Royal service depot in west London.

The interior was upgraded from the Herald, wooden door panels matched the wooden dashboard; in addition, the car had better seats and door controls. A Webasto sunroof in vinyl or fabric finishes was available as an extra on the sedan. Externally, there were stainless steel mouldings on the car's sides and aluminium bumper mouldings (instead of the Herald's white rubber mouldings). The side trim strips run the entire length of the vehicle and are also routed around the radiator grille.

About a year after its launch, the Vitesse's styling was revised for the first time; the dashboard received several round instruments instead of the single one from the Herald and from September 1965, from chassis number HB27986, the Solex twin carburettors were replaced by Zenith-Stromberg CD 150. Previously, the engine had done 70 bhp (51 kW) at 5,000 rpm and 125 Nm of torque. Now the values ​​increased enough to make the car more flexible and powerful than before. A 13-14 bhp (9.6-10.3 kW) increase in power was quoted, which was a little overoptimistic, but an engine magazine put the top speed at 146 km/h; the acceleration from 0 to 130 km/h was managed in 33.6 seconds instead of 46.6 seconds.

The Vitesse 6 sold extremely well and was the most popular Vitesse model. The car was very popular for its good driving performance and fuel economy, as well as for its elegant interior. The Vitesse had few competitors: its driving performance matched that of many sports cars (Triumph called it the "two-seater beater"), but it offered room for the whole family. The cabriolet in particular had no competitors on the market until the Stag from the same company appeared many years later.

The Vitesse 6 convertible was also exported to the United States in 1962–1964; the left-hand drive version was called Triumph Sports 6 and was marketed as a "Limited Edition" (special model). Because of its high price, only 679 units were sold.The Sports 6 was probably better suited to US highways than the Herald, but faced cutthroat price competition from cars like the Ford Mustang. The Vitesse sedan was not officially sold in the US, although some examples were imported privately, usually by American service personnel. The official retail price for the Sports 6 Cabriolet was US $2,499.

Vitesse 2-Litre

In 1966 Triumph upgraded the engine to 1998 cc, also used it for the GT6 coupe and brought out the Triumph Vitesse 2-Litre. Power increased to 95 bhp (70 kW); the new car accelerated from 0–60 mph time of just over 11 seconds (0 to 100 km/h in 13 seconds). The power increase also revealed the shortcomings of the rear suspension, which were also came from the GT6 and the Spitfire and an improved stronger differential was fitted. There were some detail improvements for the 2-Litre like a stronger gearbox all synchromesh gearbox, better brakes and "VITESSE" lettering on the aluminium strip above the reversing light and badges on the side of the bonnet with 2 litre.. in line with the new Triumph GT6 coupé, and relaunched the car as the Vitesse 2-Litre.

The Triumph Fury was a two-door convertible prototype by the Standard-Triumph Company of Coventry. It was the first monocoque sports car to be made by Triumph. Body design was by the Italian stylist Giovanni Michelotti and the car used components from the 2000 saloon including the 2.0L 6-cylinder engine of the time, although the use of the 2.5L 6-cylinder or the 3.0L Triumph V8 was possibly intended, had the car gone into production.

The car lost out to the continuation of the separate-chassis TR series, with the Triumph TR5 being introduced in August 1967. The decision by Triumph to not develop the car was due in part to the reluctance to invest in new production line and tooling facilities required to manufacture the model, in favour of continuing with the simpler manufacturing of the separate body and chassis design of the TR series.
