Chronology
Successor Hispano-Suiza J12

The Hispano-Suiza H6 is a luxury car that was produced by Hispano-Suiza, mostly in France. Introduced at the 1919 Paris Motor Show, [2] the H6 was produced until 1933. Roughly 2,350 H6, H6B, and H6C cars were produced in total.[ citation needed ]

Specifications

The H6 engine featured a straight-six engine inspired by designer Marc Birkigt's work on aircraft engines. [3] It was an all-aluminium engine displacing 6,597 cubic centimetres (403 cu in). [4] Apart from the new overhead camshaft, it was essentially half of Birkigt's aviation V12 design. [3] The seven-bearing [4] crankshaft was milled from a 600 lb (272 kg) steel billet to become a sturdy 35 lb (16 kg) unit, [2] while the block used screwed-in steel liners, [4] and the water passages were enamelled to prevent corrosion. [5]

One of the most notable features of the H6 was its brakes. They were light-alloy drums on all four wheels [5] with power-assist [2] [3] the first in the industry,[ citation needed ] driven with a special shaft from the transmission. When the car was decelerating, its own momentum drove the brake servo to provide additional power. [2] This technology was later licensed to other manufacturers, including arch-rival Rolls-Royce. [6]

The 1922 H6B was slightly more powerful. An 8.0-litre (488 cu in) (110 by 140 mm (4.3 by 5.5 in)) engine was used in 1924's H6C. [2]

The H6 series was replaced in 1933 by the J12, which initially used a 9.5-litre (580 cu in) V12 pushrod engine.

Special versions

A series of five racing H6Bs with short wheelbases and slightly enlarged engines was built in 1922. [2] These were referred to as "Boulogne", to celebrate the H6's triple victory at the sports car race at Boulogne by pilots Dubonnet, Garnier & Boyriven in 1923 (Journal des debats, July 27, 1923). [2] [6] Woolf Barnato piloted a Boulogne to eight international records, including a 92 mph (148 km/h) average over 300 mi (480 km), at Brooklands in 1924. [5]

André Dubonnet entered an H6C Boulogne in the 1924 Targa Florio. [7] Powered by a 7,982 cc (487.1 cu in) straight 6 (estimated to produce 195 hp (145 kW)), [8] Dubonnet demanded a maximum body weight of 100 lb (45 kg), [5] and the aircraft maker Nieuport- Astra complied with tulipwood strips [7] (later determined to have been mahogany),[ citation needed ] fastened to an aluminium frame with thousands of tiny rivets. [7] Dubonnet finished the gruelling event without a body failure, and drove home to Naples afterward. [8] This vehicle is currently housed at the Blackhawk Museum near Danville, California.

A later series of short-wheelbase H6Cs was built, eventually being referred to as "Monzas". [2]

Škoda

Some early H6s were built at Hispano-Suiza's industrial complex at La Sagrera, Barcelona, but most H6s were built at Hispano-Suiza's French division in the Parisian suburb of Bois-Colombes. Some 100 H6s were built under license by Škoda in Czechoslovakia from 1926 to 1929. To cope with the poor fuels available, the compression ratio had been limited to 4.5:1 and engine power to 100 hp (75 kW) at 1800rpm. [10] [11]

H6B Dubonnet Xenia

In 1938, Hispano-Suiza built a one-off H6B for André Dubonnet, in which he installed the engine from the H6C, his own custom suspension system, and custom bodywork by coachbuilder Saoutchik. This H6B served as his own personal car, as well as a showcase of his automotive technologies and aerodynamical innovations. The H6B Dubonnet Xenia is currently owned by Peter W. Mullin and is on display at the Mullin Automotive Museum in Oxnard, California.

In Miss Fisher's Murder Mysteries, Australian detective Phryne Fisher drives a red 1923 Hispano-Suiza H6, which makes frequent appearances in the television series. [12]

In several Agatha Christie novels main characters drive a Hispano. In the Novels 'the secret of Chimney's ' and 'the Seven Dials Mystery' the description fits a Hispano-Suiza Dubonnet from 1924.

Hispano-Suiza Automotive, engine, and armament manufacturer

Hispano-Suiza is a Spanish automotive–engineering company. Hispano-Suiza was founded in 1904 as an automobile manufacturer which eventually had several factories in Spain and France producing luxury cars, aircraft engines, trucks and weapons. In 1923, its French luxury car arm became a semi-autonomous partnership with the Spanish parent company. In 1946, the Spanish parent company sold all of its Spanish automotive assets to Enasa, a Spanish state-owned vehicle manufacturer while the French arm continued as an independent aviation engine and components manufacturer under the Hispano-Suiza name. In 1968, Hispano-Suiza was taken over by the aerospace company Snecma, now part of the French Safran Group. An attempt to relaunch the brand was made by the company Hispano Suiza Cars associated with the Peralada Group in 2019 with a fully electric car.

The marque came into existence in late 1956 with a front-engined Formula Two racer powered by a brand new Dino V6 engine. The name Dino was used for some models with engines smaller than 12 cylinders, it was an attempt by the company to offer a relatively low-cost sports car. The Ferrari name remained reserved for its premium V12 and flat-12 models until 1976, when "Dino" was retired in favour of full Ferrari branding.

Covini C6W Motor vehicle

The Covini C6W is an Italian 2-seat 2-door sports coupé with a removable roof section.

The project was started in 1974 but abandoned shortly after, and left dormant into the 1980s due to the lack of availability of low-profile tires at the time. In 2003 the project was revived and in 2004 the C6W was shown in prototype form. In 2005 a slightly revised version debuted at the Salon International de l'Auto, featuring new wheels, new roof structure and a refreshed interior, and went into limited production of 6-8 cars per year, as a result of a tie-up between PMI and Covini Engineering. The car features a rear, 4200 cc 8-cylinder engine and has a top speed of 186 mph (299 km/h).

One-off vehicle

In the field of vehicles authorized to drive, a one-off vehicle is a vehicle that was manufactured only once. The production of unique vehicles is reduced to one unit in each case. The easiest cases to analyze are those of cars and motorcycles. Unique automobiles and unique motorcycles are usually kept and displayed in museums. Aeronautical vehicles, with notable exceptions, are not preserved in the same way. Naval vehicles feature a myriad of unique models. A non-exclusive base of examples could be the field of sailing and motor yachts.
