Technical description
File:Ikarus 55, 1971 (6980101314).jpg
Designed as a high-floor two-axle bus, the Ikarus 55 has a semi-self supporting body, with the engine installed behind the rear seats at the back. Both front and rear axles are leaf-sprung beam axles, with the rear axle being a live planetary axle. Only the front axle has hydraulic shock absorbers. Twin tyres are fitted on the rear axle, whilst single tyres are fitted on the front axle. Their dimension is {{convert|11–20|in|mm|0|abbr=on}}. The steering system is fully mechanical and not power assisted. A pneumatic braking system is installed, all four wheels have drum brakes. The parking brake is foot-operated.
The Ikarus 55 is powered by a water-cooled, naturally aspirated, {{convert|8.3|L|cuin|adj=on}} Csepel D-614 swirl chamber injected straight-six Diesel engine. This engine is a modified Steyr WD 613 engine with an enlarged cylinder bore, that was built under licence by Csepel. It is rated DIN {{convert|145|PS|kW hp|abbr=on|lk=in}} with a maximum torque of {{convert|50|kpm|Nm|0|abbr=on}}. The torque is transmitted to a partial synchromesh five-speed gearbox via a single-disc dry clutch. Depending on the gear ratio, the top speed is in between {{convert|78 and 98|km/h|mph|abbr=on}}. The engine's best fuel consumption is rated approximately 190 g·PS−1·h−1 (258 g·kW−1·h−1)
