The story
History
In 1907 the Centre Excursionista de Catalunya chose José María Armangué, aged 17, to drive one of its bobsleighs in the Coupe du Président de la République.source 1 There was no snow, so he put the sled on wheels and made a “down-car”, which he raced down the Tibidabo and the Rabassada road. Tired of pushing it back up, he fitted it with a motor.source 1source 2source 3 Down-car racing on the Tibidabo became popular, and in 1910 the brothers José María and Ramón Moré won the Copa Barcelona with one.source 1source 3 Before 1913 the Armangué brothers designed a four-stroke engine, which was never built, and patented a progressive gear change that became a hallmark of the cars to come.source 3
With his brothers or cousins Luis and Federico (“Frick”) Armangué, the Moré brothers, Fernando Comas, the Puig brothers and others, Armangué built the first car in 1913, in Sebastián Juanico’s workshop on the Avinguda del Tibidabo, a name often misspelt “Juanito”.source 1source 2source 3 They called it David, because the little car could take on much bigger ones.source 1source 4source 2 On 14 July 1914 the Fábrica Nacional de Autociclos David was founded in Barcelona with 65,000 pesetas of capital, when Armangué was 24, and by 1915, according to a newspaper article of 2014, about a hundred cars had been built. The works later stood at carrer Pallars 71, now 77, in Poblenou.source 1source 4source 2
Belts and a wide track
The David had a wooden frame, independent front suspension by transverse leaf springs one above the other, and a very wide track, which the RACC’s history of Catalan motoring credits with great stability and agility. Twin belts drove the rear wheels at an adjustable ratio, through the Armangués’ patented progressive change.source 2source 3 English Wikipedia says the belts and pulleys gave 16 speeds, and that the car had front-wheel brakes, but cites no source for either.source 5 The engines grew from air-cooled JAP V-twins to water-cooled MAG twins and fours, and from 1919 Davids had Hispano-Suiza, Ballot and Elizalde engines.source 1source 2 The same history says the most powerful could reach 130 km/h (81 mph) on the flat, a figure that is high for a cyclecar.source 2 There were two- and four-seaters and closed versions, and the duc de Montpensier ordered one; the model named after him was “the most perfected of the Davids”.source 4source 2
