Depending on the country, different engines from the Hungarian manufacturer Rába under license from MAN were used for the bus . A manually shiftable, synchronized six-speed gearbox was installed as the gearbox . As with the shorter Ikarus 256 , the engine is located in the rear and drives the transmission via a single-disk dry clutch and an outer planetary gear drive the rear axle of the vehicle. With this drive unit, the bus can reach a top speed of 106 km / h.
Like the Ikarus 556 , the bus was fitted with rigid axles, but with air suspension . With an empty weight of 10.7 t, the permissible total weight is 16.0 t. The pneumatic brake acts on all wheels and is supplemented by a spring-loaded parking brake and an engine brake . For the first time at Ikarus, power steering was used on this bus .
A self-supporting structure was placed on the floor pan. With its clear forms, the design corresponded to the zeitgeist of the late 1960s. As a coach, the bus offered 42 to 46 seats. The trunk, accessible from the outside through flaps, is located under the seats. The coaches in this class have two doors. In the course of the long production period of more than twenty years, initially manually operated doors, later also double or single-leaf swing doors and a combination thereof were installed. Different body variants with different equipment, especially as a conference bus, also with engines from other manufacturers, were produced.
As part of the Comecon Agreement, Ikarus buses were imported in large numbers into the GDR . The 250 series was delivered to the transport company from 1968 to 1989. In September 1988 there were 218 copies of the Ikarus 250 in the GDR.
