David (car)
David was a Spanish company manufacturing automobiles in Barcelona between 1913 and 1923 and again between 1951 and 1957. The original cars, developed by José Maria Armangué, were cyclecars using either a single cylinder 6–8 hp, or four-cylinder 6–8 hp, or 10–12 hp engine; and belt and pulley transmission giving 16 speeds and featuring front wheel brakes. Bodies were usually open two-seater, but 3-seat and closed versions were also made. Cyclecar production seems to have stopped in 1923, but the company continued making taxi bodies for fitting on Citroën chassis, for which they were Spanish distributors. Car production started again in 1951 with a new generation of 3-wheeler light cars powered by single-cylinder two-stroke A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one r ...

Cyclecar
A cyclecar was a type of small, lightweight and inexpensive car manufactured in Europe and the United States between 1910 and the early 1920s. The purpose of cyclecars was to fill a gap in the market between the motorcycle and the car. A key characteristic was that it could only accommodate two passengers sitting tandem style or passenger behind the driver. The demise of cyclecars was due to larger cars – such as the Citroën Type C, Austin 7 and Morris Cowley – becoming more affordable. Small, inexpensive vehicles reappeared after World War II, and were known as microcars. Characteristics Cyclecars were propelled by engines with a single cylinder or V-twin configuration (or occasionally a four cylinder engine), which were often air-cooled. Sometimes motorcycle engines were used, in which case the motorcycle gearbox was also used. All cyclecars were required to have clutches and variable gears. This requirement could be fulfilled by even the simplest devi ...

Citroën
Citroën () is a French automobile brand. The "Automobiles Citroën" manufacturing company was founded in March 1919 by André Citroën. Citroën is owned by Stellantis since 2021 and previously was part of the PSA Group after Peugeot acquired 89.95% share in 1976. Citroën's head office is located in the Stellantis Poissy Plant in Saint-Ouen-sur-Seine since 2021 (previously in Rueil-Malmaison) and its offices studies and research in Vélizy-Villacoublay, Poissy (CEMR), Carrières-sous-Poissy and Sochaux-Montbéliard. In 1934, the firm established its reputation for innovative technology with the Traction Avant. This was the world's first car to be mass-produced with front-wheel drive, four-wheel independent suspension, as well as unibody construction, omitting a separate chassis, and instead using the body of the car itself as its main load-bearing structure. In 1954, they produced the world's first hydropneumatic self-levelling suspension system then, in 1955, the revolutio ...

Two-stroke
A two-stroke (or two-stroke cycle) engine is a type of internal combustion engine that completes a power cycle with two strokes (up and down movements) of the piston during one power cycle, this power cycle being completed in one revolution of the crankshaft. A four-stroke engine requires four strokes of the piston to complete a power cycle during two crankshaft revolutions. In a two-stroke engine, the end of the combustion stroke and the beginning of the compression stroke happen simultaneously, with the intake and exhaust (or scavenging) functions occurring at the same time. Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the power band. Two-stroke engines have fewer moving parts than four-stroke engines. History The first commercial two-stroke engine involving cylinder compression is attributed to Scottish engineer Dugald Clerk, who patented his design in 1881. However, unlike most later t ...

Microcars
Microcar is a term often used for the smallest size of cars, with three or four wheels and often an engine smaller than . Specific types of microcars include bubble cars, cycle cars, invacar, quadricycles and voiturettes. Microcars are often covered by separate regulations to normal cars, having relaxed requirements for registration and licensing. Predecessors Voiturette is a term used by some small cars and tricycles manufactured from 1895 to 1910. Cyclecars are a type of small, lightweight and inexpensive car manufactured mainly between 1910 and the late 1920s. Europe 1940-1970: Microcars The first cars to be described as microcars (earlier equivalents were called voiturettes or cyclecars) were built in the United Kingdom and Germany following World War II, and remained popular until the 1960s. They were originally called minicars, but later became known as microcars. France also produced large numbers of similar tiny vehicles called voiturettes, but they were ra ...

Manufacturing Companies Based In Barcelona
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed into a final ...
