Originally, OM manufactured railway stock. Car production started in 1918, using the plant of the former Brixia-Zust (Brixia-Züst), just after OM took over Zust car company of Brescia, Northern Italy. The first OM car, Tipo S305, primarily an old Zust model, appeared in 1918 with a 4712 cc four-cylinder side-valve in-line engine.

Further models were Tipo 465 (with a 1327 cc four) in 1919, Tipo 467 (1410cc) and Tipo 469 (1496cc) in 1921. 1923 saw an all new model, Tipo 665 ‘Superba’ with a 2-litre six-cylinder engine. This model was extremely successful in racing – won top five positions in the 2-litre class in 1925 and 1926 at Le Mans but the greatest achievement was the victory in the first Mille Miglia race in 1927 where Ferdinando Minoia and Giuseppe Morandi lead home an O.M. ‘123’ at average speed of 48.27 miles per hour (77.7 km/h) for 21 hours 4 minutes 48seconds. Some cars were equipped with Roots superchargers.

Main new product in the WWII post-war era was the Leoncino (1950) a light truck in the 2.0 to 2.5 tons range, which was an immediate success. It became the forefather of several series of heavier but structurally similar models, namely TigrottoTigreLupettoCerbiatto and Daino, launched between 1957 and 1964. Bus chassis versions of several of these models were also available.

Author: Jeroen

In Dutch, my homelanguage: Ik ben Jeroen, tot januari 2015 was ik al dik 26 jaar werkzaam in een psychiatrisch ziekenhuis in een stad vlakbij Werelds grootste havenstad Rotterdam. Eerst als verpleegkundige/begeleider op high care, later op afdeling dubbeldiagnose (verslavingen) en ook nog een tijdje als administratief medewerker. Ik heb een spierziekte "Poli Myositis" (alle spieren zijn ontstoken) daardoor weinig energie. Sinds augustus 2015 is daarbij de diagnose Kanker gesteld, en ben ik helemaal arbeidsongeschikt geworden en zit middenin de behandelfase. Gelukkig ben ik daarnaast getrouwd, vader, en opa, en heb de nodige hobby's. Een daarvan is transportmiddelen verzamelen en daarmee een blog schrijven. Dit blog begon met bussen, maar nu komen ook sleepboten, auto's trucks en dergelijke aan bod. Kijk en geniet met me mee, reageer, en vul gerust aan. Fouten zal ik ook graag verbeteren. In English: I'm Jeroen, till januari 2015 I was already 26 years working as a nurse in a psychiatric hospital, near Rotterdam, Worlds biggest harbour with more than 98 nationalities living within it's borders. First I worked on closed high care ward and the last years on a ward with mainly addicted people. I liked my work very much. In 2007 I got ill. I got the diagnose Poli Myositis, a musscle dissease. Al my mussles are inflamed. And last august I got another diagnose. Cancer. It's plaveicelcel carcinoma and treated with Chemo and radioation. So I've even less energy than the last years. Still I try to make something of my life and the blog is helping with surviving with some pleasure.

  6. Hi,
    Great post about OM, just to add that in former Yugoslavia a lot of OM busses were assembled by local coachbuilders like TVT Boris Kidrič, Maribor (later merged with TAM (Tovarna Avtomobilov in Motorjev), Boris Kidrič, Maribor doesnt exist anymore but TAM operates by TAM Europe name), Avtomontaža, Ljubljana (they assembled most of OM buses, they dont exist anymore, they were largest coachbuilders in Yugoslavia and Slovenia later on but they ceased to exist) and Autokaroserija, Zagreb (they dont exist anymore). I dont discount that maybe more coachbuilders in Yugoslavia assembled them. All of the OM busses in Yugoslavia as far as I know were assembled during 1950s and 1960s and all the models were assembled (Lupetto,Leoncino,Tigrotto,Tigre,Orione,Super Orione,Titano(as far as I know in Italy Titano buses were newer assembled,only those form 1930s).


    1. Just to add, I recently discovered that Super Taurus was assembled,too in Yugoslavia. Most of OM buses had steering wheel on the right, Super Taurus and Titano had steering wheel on the left.
