Additional Notes
- The Irisbus Arway carries 6.5 liters of power steering fluid across both the 10-13m and 15m Euro 4 body length variants for the 2005-2013 model years.
- A 6.5-liter capacity is notably high compared to passenger cars, which reflects the demands of a hydraulic steering system on a full-size coach platform where steering effort and fluid volume requirements are substantially greater.
- Both configurations are specified under normal use conditions, meaning the 6.5-liter figure applies to standard operating environments rather than severe-duty cycles.
- The shared capacity between the shorter 10-13m and the longer 15m body lengths indicates the hydraulic power steering system architecture is consistent across the Arway's available length configurations within the Euro 4 generation.
