The Austin 7 is an economy car that was produced from 1923 until 1939 in the United Kingdom by 
Until the First World War, Austin built mainly large cars, but in 1909 they sold a single-cylinder small car built by Swift Motor Company, Swift of Coventry called the Austin 7 hp. After this they returned to bigger cars.
In 1920 Herbert Austin, 1st Baron Austin, Sir Herbert Austin commenced working on the concept of a smaller car, mainly to meet the needs of young families aspiring to own an affordable motor car. This idea was spurred on by the introduction of the Tax horsepower, Horsepower Tax in 1921. His design concept marked a departure from his company's conservative motoring past and Austin received considerable opposition from his board of directors and creditors. Because the company was in receivership, Austin decided to carry out the project himself, and in 1921 hired an 18-year-old draughtsman, Stanley Edge, from the Austin factory at Longbridge, Birmingham to aid in the drawing of detailed plans. This work was carried out in the billiard room of Austin's Lickey Grange home.
Edge convinced Austin to use a small four-cylinder engine. The original side valve engine design featured a capacity of 696cc (55mm x 77mm) giving a RAC rating of 7.2 hp, the cast cylinder block featured a detachable head and was mounted on an aluminium crankcase. The crankshaft used one roller and two ball bearings and the big-ends were splash lubrication, splash lubricated. Edge also carried out the design of other mechanical components such as the three speed gearbox and clutch assembly. Austin was largely responsible for styling the Seven's design, which was reportedly influenced by the design of the Peugeot Quadrilette. The "A" frame chassis design was believed to have been influenced by the design of an American truck used in the Longbridge factory in the early 1920s.
The design was completed in 1922 and three prototypes were constructed in a special area of the Longbridge factory, and announced to the public in July 1922. Austin had put a large amount of his own money into the design and patented many of its innovations in his own name. In return for his investment he was paid a royalties, royalty of two guinea (British coin), guineas (£2, 2s), (£2.10) on every car sold.
Nearly 2,500 cars were made in the first year of production (1923), not as many as hoped, but within a few years the "big car in miniature" had wiped out the cyclecar industry and transformed the fortunes of the Austin Motor Co. By 1939 when production finally ended, 290,000 cars and vans had been made.
The original 1922 four-cylinder Austin Seven engine had a bore of 2.125" (54mm) and stroke of 3" (76mm), giving a capacity of 696 cc and RAC rating of 7.2 hp. From March 1923 the bore was increased to 2.2" (56mm) giving 747 cc and 10.5 hp. The side-valve engine was composed of an aluminium crankcase, cast iron cylinder block and cast iron cylinder head. Cooling was by thermosiphon, without a water pump, and the dynamo was driven from the timing gears.
The big end bearings were lubricated by jets from an oil gallery in the crankcase, the oil striking the crankshaft webs which were drilled accordingly. Originally the journal diameter was 1.125"; this was later increased to 1.3125". The three bearing engine (from 1936) used a white metal centre bearing.
The splash-lubricated crankshaft (pressure fed on some sports models) at first ran in two bearings (two ball bearings at the front, roller at the back) changing to three in 1936. An electric starter was fitted from November 1923. The early cars used magneto ignition, but this was changed to coil in 1928.
The 3-speed and reverse gearbox was bolted to the back of the engine and had a variety of ratios depending on the application: touring, sports, racing and trials. A four-speed gearbox was introduced in 1932 and in 1933 synchromesh was added to third and top ratios extending to second gear in 1934.
The back axle was of spiral bevel gear, spiral bevel type with ratios between 4.4:1 and 5.6:1 with 4.9:1 being the most common until the 1930s. A short torque tube ran forward from the differential (mechanical device), differential housing to a bearing and bracket on the rear axle cross member.
Reliant used a derivative of the Austin Seven engine for their early three-wheelers, before developing a new aluminium alloy engine (used as the replacement for the Austin Seven engine by the 750 Motor Club in their 750 Formula, Formula 750 motor sport) introduced in the 1962 Reliant Regal 3/25.
Herbert Austin's son-in-law, Arthur Waite, soon began to achieve remarkable sporting successes beginning at Brooklands in March 1923 and the next month at Autodromo Nazionale Monza, Monza. Another driver, E C Gordon England, persuaded Sir Herbert to provide him with a racing 7. Waite and Lou Kings (chief tester) then experienced a run of failure brought about by inadequate engine lubrication for racing conditions. Meanwhile, Gordon England, flushed with success from establishing six new class records at Brooklands, had built a special lightweight 2-seater body weighing just and entered it in the 1100 cc class for the Junior Car Club 200 mile race at Brooklands in October 1923. There England finished in second place and during the race won another five class records.
As a result two new sports models were offered by Austin in January 1924, the Sports and the Brooklands Super-sports. The Brooklands Super-sports was a replica of England's record-breaker. Each car was sold with a Brooklands certificate proving a speed of per hour. By 1925 Gordon England held nineteen 750 cc class records.
In 1927, William Lyons, co-founder of the Swallow Sidecar Company, saw the commercial potential of producing a re-bodied Austin 7. Buying a chassis from dealer Parkers of Bolton Lyons commissioned Swallow's talented employee, coachbuilder Cyril Holland, to produce a distinctive open tourer: the Austin Seven Swallow. Holland (1895- ) who joined Swallow in late 1926 had served his apprenticeship with Lanchester Motor Company, Lanchester and would become chief body engineer. The height of saloon car fashion of the day was to have the back of the body fully rounded, this was called "dome" shaped.
With its bright two-tone colour scheme and a style befitting more expensive cars of the time, together with its low cost (£175), the Swallow proved popular and was followed in 1928 by a saloon version: the Austin Seven Swallow Saloon.
Approximately 3,500 bodies of various styles were produced up until 1932, when Lyons started making complete cars under the SS Cars Ltd, SS brand.
Such was the demand for the Austin Seven Swallows that Lyons was forced to move in 1928 from Blackpool to new premises in Coventry. It was, in part, the success of the Swallows that laid the foundations of what was to become, by 1945, Jaguar Cars.

Austin Seven 1936
The largest and best known of these Australian coach-builders was Holden, Holden's Motor Body Builders. Holden built Australian-bodied Austin Seven tourer and roadster models from the mid 1920s.
However, several smaller coach-builders built limited numbers of Australian-bodied Austin Seven sports models between 1924-34. Some examples of these Australian-bodied sports models are; the Standard Sports, built by Flood Motor Body Works, St Kilda Road, Melbourne; the Wasp built by William Green, Parramatta Road, Petersham, Sydney; the Moth built by Geo Sykes, Gordon Road, Chatswood, Sydney; the Comet built by Bill Conoulty, Sydney; and the Meteor. The Meteor was built by several coach-builders (Flood Motor Body Works, St Kilda Road, Melbourne; Jack Lonzar, Kent Town Adelaide; and A Robinson & Co., 181 Castlereagh St, Sydney), with individual variations to the common design.
The Ulster gained its name from a strong performance in the 1929 RAC Tourist Trophy held at the Ards circuit in County Down, where Archie Frazer-Nash finished third and S. V. Holbrook finished fourth.
In Australia Arthur Waite (racing driver), Arthur Waite won the 1928 100 Miles Road Race driving an Austin 7.

Chassis
The Austin 7 was considerably smaller than the Ford Model T. The wheelbase was only 6 ft 3 inches (1.905 m), and the track only 40 inches (1.016 m). Equally it was lighter – less than half the Ford Model T, Ford's weight at 794 pounds (360 kg). The engine required for adequate performance was therefore equally reduced and the 747 cc sidevalve was quite capable with a modest actual 10 hp output. The chassis took the form of an "A" with the engine mounted between the channel sections at the narrow front end. The rear suspension was by quarter elliptic springs cantilevered from the rear of the chassis while at the front the beam axle had a centrally mounted half elliptic transverse spring. Brakes were on all wheels but at first the front brakes were operated by the handbrake and the rear by the footbrake, becoming fully coupled in 1930. In late 1931 the chassis was lengthened by 6" with a corresponding increase in the rear track. Steering is by Worm gear, worm and wheel mechanism.Engine and transmission
The original 1922 four-cylinder Austin Seven engine had a bore of 2.125" (54mm) and stroke of 3" (76mm), giving a capacity of 696 cc and RAC rating of 7.2 hp. From March 1923 the bore was increased to 2.2" (56mm) giving 747 cc and 10.5 hp. The side-valve engine was composed of an aluminium crankcase, cast iron cylinder block and cast iron cylinder head. Cooling was by thermosiphon, without a water pump, and the dynamo was driven from the timing gears.

Austin Seven saloon by Gordon England
The first Austin 7 sedan (car), saloon was made by Gordon England (coachbuilder), England's coachbuilding company. England had been an aircraft designer with Bristol Gordon England biplanes. His fabric saloon body based on aircraft principles was said to be the smallest closed car in the world. Its body weighed less than the tourer and at £210, almost double the £112 chassis price. It showed there would be a market for an Austin-made steel-panelled saloon which was introduced in September 1926 at £165 (equivalent to £ today) Until fabric bodies fell from fashion in the early 1930s the Gordon England Fabric "de luxe" Saloon remained in Austin's catalogue at a £20 (14%) premium over Austin's standard steel sedan (car), saloon. It was accompanied by their 2-seater Gordon England Cup Model.Austin Seven Swallow
In 1927, William Lyons, co-founder of the Swallow Sidecar Company, saw the commercial potential of producing a re-bodied Austin 7.

was founded in 1929, in Butler, Pennsylvania, Butler, Pennsylvania, in premises that had belonged to the Standard Steel Car Company. Their intention was to assemble and sell in the United States a version of the Austin 7 car, called American Austin. After some initial success the Great Depression set in, and sales fell off to the point that production was suspended. In 1934 the company filed for bankruptcy.
The automobile was designed in the hopes of creating a market for small-car enthusiasts in the United States. The cars had inline-four engines, enabling the car to return , and travel per fill of oil.
Australian-bodied Austin Sevens
In the aftermath of World War I the Australian Government imposed a tariff on imported vehicles, with tax concessions applying to rolling chassis, as a stimulus to develop a sovereign motor vehicle industry. The chassis concession acted as a financial incentive for local coach-builders to import factory built rolling chassis, and fit uniquely Australian designed and built bodies, leading to the establishment of an Australian motor vehicle bodybuilding industry in the early 1920s.
The largest and best known of these Australian coach-builders was Holden, Holden's Motor Body Builders. Holden built Australian-bodied Austin Seven tourer and roadster models from the mid 1920s.
However, several smaller coach-builders built limited numbers of Australian-bodied Austin Seven sports models between 1924-34.

Layout
In 2007, during an episode of ''Top Gear (current format), Top Gear'', Jeremy Clarkson and James May studied a number of early car designs (including the Ford Model T and the De Dion-Bouton Model Q) and concluded that the Austin Seven was the first mass-market car to be fitted with a "conventional" control layout, as found on modern cars (although the earliest car they found to use this layout was a Cadillac Type 53 in 1916).Body styles
