The very successful
F series of city and inter-city buses (named after Fostiropoulos initial, a designation used earlier as well) was introduced in 1965 employing a ladder-type chassis developed by BIAMAX, and, as most of its products,
Mercedes-Benz engines. The most common types produced were the
F530 and
F580, with several body variations for a variety of end uses. At the same time BIAMAX introduced railway wagons, and kept producing an extended range of bus and truck bodies, assembling 4x4's and tractors etc., with thousands of vehicles coming out of its factories, many of which were exported to a large number of countries, mainly in Europe, Asia and Africa; at times the company exported as much as 50% of its production. One of the most notable models specifically developed for Africa and the Middle East was the "
Desert Bus", an extremely rugged construction whose production started in 1963, for long distance travel with cross-country and extra load capabilities (including the capability to carry tons of load on its roof), optionally with A/C, beds, toilets etc. F580 types can be seen to this date working hard in the Middle East. Indeed, the legendary reliability of BIAMAX buses can be testified by the large number of surviving examples, most of them in excellent working condition. One of the most successful ventures of Biamax was the production of
Mercedes-Benz O302 and
O303 coaches, including variants like the
O302S2 type, which essentially was a "blend" of both models. == Evolutions after 1980 ==
