Ok, here are some buses
The Ikarus airplane factory from Zemun, Yugoslavia (now days Serbia) has switched during the late 1960's from aircraft production in to bus production. The communist government of Yugoslavia has decided to move military production from Zemun to the Soko factory in Mostar, now days Bosnia and Herzegovina. Since then Ikarus Zemun is one of main bus producer in former Yugoslavia, mainly producing city buses for public transport. It had successful export to Romania, Poland, Soviet Union, Turkey and Cuba. In 1993. the factory change it's name from Ikarus in to Ikarbus, due the dispute with famous Hungarian bus producer which had the same name.
Here is the first Ikarus model I have drawn, it is IK 160 and IK 161, visually same models, but different in engines and some other mechanical details.
The IK-160 was produced from 1982 until 1989. The "160B" version had Hungarian Raba engine. Model "160P" was produced in Poland by Jelcz under license with SW680 engine.
The IK-161 was later introduced in to production. The "161B" version had MAN engine, while "161R" had Raba engine. It was produced until 1996., from 1993. under Ikarbus name. The model "162" has more seats and it's used for suburban public transport.
