Diatto was an Italian manufacturing company founded in 1835 in Turin by Guglielmo Diatto to make 'carriages for wealthy customers'. In 1874 Guglielmo’s sons, Giovanni and Battista Diatto, began building railway carriages for Compagnie Internationale des Wagons-Lits and the Orient Express. In 1905 Guglielmo's grandsons, Vittorio and Pietro Diatto, began Diatto-Clément, a cooperative venture making motor-vehicles under license from French manufacturer Clément-Bayard owned by industrialist Adolphe Clément-Bayard. By 1909 they had full ownership of 'Autocostruzioni Diatto' and began developing their own motor-vehicles and exporting them worldwide.
From 1905 the company built two and four cylinder cars based on the Clément-Bayard, a leading contemporary French manufacturer. By the 1920s, Diatto was making quality cars of its own design, including race cars with supercharged eight-cylinder engines. Diatto also supplied frames to Bugatti which used them for their own race cars. Some Diatto racers were prepared and raced by Alfieri Maserati who left Diatto in 1926 to establish the Maserati marque with his brothers.
Diatto cars were known for their innovative engineering and as early as the 1920s they were equipped with four-wheel brakes and four-speed gearboxes.
Diatto ceased production in 1929.
|Pietro and Vittorio Diatto, founders|
In 1835 Guglielmo Diatto, a 30-year-old wheelwright from Carmagnola, founded a workshop on the banks of the river Po in Turin for the manufacture and repair of carriage wheels. The business developed into building carriages for nobility and Diatto Manifattura di Carrozze (Carriage Manufacture) became a successful industrial concern.
In 1838 Guglielmo Diatto was awarded his first patent for a 'perfected wheel'. The patent is held at the 'National Museum of Automobiles' in Turin.
In 1874 the founder’s sons, Giovanni and Battista, began building luxury railway carriages for Compagnie des Wagons Lits et des Grands Express Europeens of Paris who ran the Orient Express, the Nord Express, the Sud Express and the Transsibérien across Russia.
In 1905 the grandsons of the founder, Vittorio and Pietro Diatto, believed that motor-vehicle production represented the future for the 'carriage market'. On 12 April 1905, they founded the Società Diatto-A. Clement in partnership with the French company Clément-Bayard, owned by Adolphe Clément-Bayard of Paris. Diatto-Clément had a workforce of 500 (Note: Fiat had 776) and produced cars with 4 and 6 cylinder engines.
The company achieved significant sporting success from the outset. In 1906 it won the Herkomer Competition in Germany against 134 competitors (1800 km from Frankfurt to Innsbruk); the Lugano-San Gottardo (speed trial over 7 hours through the mountain passes) in Switzerland; and the Italian Gold Cup, defeating 48 competitors over 4000 km in 11 daily stages across Italy.
In 1909 the Diatto brothers bought out Adolphe Clément-Bayard and renamed the company 'Autocostruzioni Diatto'. The new company continued with its sporting reputation and traded on the slogan : Queen of lightweight vehicles, fast, comfortable, elegant.
The company developed a worldwide sales and support network, with vehicles being exported to :
From 1912 onwards Diatto expanded rapidly, becoming one of the top Italian industrial groups. In 1915, it acquired both the Scacchi factory in Chivasso, in which the workforce of 100 built five cars per month,[n 1] and the 'Vetture Automobili Leggere Torino' (V.A.L.T.) factory.de:Vetture Automobili Leggere Torino[n 2] It then consolidated both the workforces and plant in the new factory in 'Via Frejus' (Turin) where they were able to produce over 40 units a month.
Diatto acquired a controlling share of the leading aviation engine manufacturer Gnome et Rhône from 'Weiter and Waugham'. Gnome manufactured around 200 rotary aviation engines per month. Under Diatto ownership their technological know-how was also integrated into the motor-vehicles.
The Gnome et Rhone 9 cylinder rotary engine won several prestigious trans-European prizes such as the Mediterranean crossing; the Gordon Bennet Cup; the Reims Meeting; plus the Raids of Friedrichshafen, Düsseldorf, Cuxhaven, Zeebrugge, and Dunkerque. The build-up to World War 1 lead to orders for 5,000 aviation engines for Italy, Russia, France and United Kingdom.
After the first world war they added 8 cylinder supercharged engines with aluminium pistons and 4 valves per cylinder, up to 6,000 cc.
On 9 February 2007 Zagato announced the revival of the Diatto marque to celebrate its 100th anniversary. At the 77th Geneva Motor Show in March 2007 it unveiled a new all-aluminum sports car called the Diatto Ottovù Zagato.

The automotive industry in Italy is a quite large employer in the country, it had over 2,131 firms and employed almost 250,000 people in 2006. Italy's automotive industry is best known for its automobile designs and small city cars, sports and supercars. The automotive industry makes a contribution of 8.5% to Italian GDP.Italy is one of the significant automobile producers both in Europe and across the world.
Today the Italian automotive industry is almost totally dominated by Fiat Group; in 2001 over 90% of vehicles were produced by it. As well as its own, predominantly mass market model range, Fiat owns the upmarket Alfa Romeo and Lancia brands and the exotic Maserati.
Italian cars won in the European Car of the Year annual award one of the most times among other countries (including Fiat most that any other manufacturer) and in World Car of the Year award also.Carmagnola

For cycle, motor-cycle, motor-car, aeroplane and airship companies associated with French industrialist Adolphe Clément-Bayard - see Clement (disambiguation).Diatto-Clément, Diatto A Clément, was an Franco Italian manufacturer of motor vehicles between 1905 and 1909. Adolphe Clément-Bayard created the 'Diatto-Clément Societa Anonima' in partnership with Diatto who had been coachbuilders in Turin since 1835.The Diatto-Clément cars, known as Torinos, were built in Turin under licence from Clément, thus in Italy they were known as 'Diatto A Clément'. The first car was the 20-25HP which used a 3,770cc four cylinder engine. This was followed by a 10-12HP (1,884cc two-cylinder) and a 14-18HP (2,724cc four-cylinder). This series was a success and was followed by a six-cylinder model.In 1909 Clément-Bayard left the business and the company was renamed 'Societa Fonderie Officine Frejus'.Giovanni Gagliardi drove a Diatto Clément 10/12 hp to class victory in the Milano-Sanremo race on 4-5 April 1906.

The Diatto Ottovù Zagato is a sports car designed and built by Milanese coachbuilder Carrozzeria Zagato for two of its clients. Coinciding with the 100th anniversary of the Diatto brand, the car made its official public debut at the 2007 Geneva Motor Show. The word Otto appears, in various forms, three times in the car's name.
Back in 1921, Ugo Zagato designed a lightweight and aerodynamic body for the Diatto 25 4DS chassis. Created in 1835 with a Perfected Wheel patent, Diatto made their first car in 1905 and often crossed paths with Zagato in their close collaboration with Ettore Bugatti, the Maserati brothers and Tazio Nuvolari.
The word "Ottovù" incidentally means "V8" in Italian. A clear indication of the engine powering this vehicle and show of the car's sporting intent.Emilio Materassi

The Maserati Tipo 26 was a model of Grand Prix racing car and was the first car built by Italian manufacturer Maserati, for a total of 11 examples, between 1926 and 1932.The Tipo 26 originated from a Grand Prix car that Alfieri Maserati had designed for Diatto: when the collaboration between Maserati and Diatto ended, Alfieri took his design to the Bologna workshop that he had set up with his brothers in 1914.The design of the Tipo 26 consisted of a steel ladder-type frame supporting a supercharged inline-8 engine with a three-speed manual transmission and an aluminum two-seater bodywork made by Medardo Fantuzzi.The engine featured a crankshaft-driven Roots supercharger, twin gear-driven overhead camshafts and dry sump lubrication; to comply with the 1926 Grand Prix regulations the displacement was fixed to 1.5-litres.At its debut race in the 1926 Targa Florio, the Maserati Tipo 26, with Alfieri Maserati driving and a young Guerino Bertocchi as riding mechanic, finished first in the Grand Prix class and ninth overall.Stud contact system
The stud contact system is a once-obsolete ground-level power supply system for electric trams. Power supply studs were set in the road at intervals and connected to a buried electric cable by switches operated by magnets on the tramcars. Current was collected from the studs by a "skate" or "ski collector" under the tramcar. The system was popular for a while in the early 1900s but soon fell out of favour because of the unreliability of the magnetic switches.
In recent years the concept has made a comeback, to remove overhead supply systems from scenically sensitive areas. Current manufacturing methods and electronic control means such systems are much more reliable. The new tram system in Bordeaux, France has resurrected the system in the form of Alimentation par le sol for aesthetic reasons in the city centre.Targa Rignano
The Padova - Bovolenta race (1900–1908) was an automobile, voiturette and motorcycle race. The first day had a 10-kilometre (6.2 mi) straight race speedrecord track between the cities of Padova and Bovolenta in Italy, followed by a 1-kilometre (0.62 mi) race in Padova the next day. The name Targa Rignano was only used in the years 1902, 1903 and 1904, as conte Rignano was involved. The race was not held 1905 to 1908, and after a fatal spectator accident involving Diatto-driver Dal Torso (1908), the Italian Parliament asked for it to end.Zagato
