The Hispano-Suiza H6 is a luxury car that was produced by Hispano-Suiza, mostly in France. Introduced at the 1919 Paris Motor Show,[1] the H6 was produced until 1933. Roughly 2,350 H6, H6B, and H6C cars were produced in total.Script error: No such module "Unsubst".
Specifications
The H6 engine featured a straight-six engine inspired by designer Marc Birkigt's work on aircraft engines.[2] It was an all-aluminium engine displacing Script error: No such module "convert"..[3] Apart from the new overhead camshaft, it was essentially half of Birkigt's aviation V12 design.[2] The seven-bearing[3] crankshaft was milled from a Script error: No such module "convert". steel billet to become a sturdy Script error: No such module "convert". unit,[1] while the block used screwed-in steel liners,[3] and the water passages were enamelled to prevent corrosion.[4]
One of the most notable features of the H6 was its brakes. They were light-alloy drums on all four wheels[4] with power-assist[1][2] the first in the industry,Script error: No such module "Unsubst". driven with a special shaft from the transmission. When the car was decelerating, its own momentum drove the brake servo to provide additional power.[1] This technology was later licensed to other manufacturers, including arch-rival Rolls-Royce.[5]
The 1922 H6B was slightly more powerful. An Script error: No such module "convert". (Script error: No such module "convert".) engine was used in 1924's H6C.[1]
The H6 series was replaced in 1933 by the J12, which initially used a Script error: No such module "convert". V12 pushrod engine.
Special versions
A series of five racing H6Bs with short wheelbases and slightly enlarged engines was built in 1922.[1] These were referred to as "Boulogne", to celebrate the H6's triple victory at the sports car race at Boulogne by pilots Dubonnet, Garnier, and Boyriven in 1923 (Journal des debats, July 27, 1923).[1][5] Woolf Barnato piloted a Boulogne to eight international records, including a Script error: No such module "convert". average over Script error: No such module "convert"., at Brooklands in 1924.[4]

André Dubonnet entered an H6C Boulogne in the 1924 Targa Florio.[6] Powered by a Script error: No such module "convert". straight 6 (estimated to produce Script error: No such module "convert".),[7] Dubonnet demanded a maximum body weight of Script error: No such module "convert".,[4] and the aircraft maker Nieuport- Astra complied with tulipwood strips[6] (later determined to have been mahogany),Script error: No such module "Unsubst". fastened to an aluminium frame with thousands of tiny rivets.[6] Dubonnet finished the gruelling event without a body failure, and drove home to Naples afterward.[7] 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".[1]
A six-wheeled H6A was ordered by the King of Greece, but after his abdication was purchased by the motion picture director D. W. Griffith. It is now at the Forney Museum in Denver.[8]

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 Script error: No such module "convert". at 1800rpm.[9][10]
H6B Dubonnet Xenia
Script error: No such module "Labelled list hatnote". 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 personal car, as well as a showcase of his automotive technologies and aerodynamic innovations. The H6B Dubonnet Xenia is currently owned by and is on display at the Petersen Automotive Museum in Los Angeles, California.
In popular culture
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.[11]
