Lower cost of operation was a driving force in the
design and engineering of Enviro400 and has been achieved through both detail improvements and major advances in downtime minimisation.

Notable examples include the use of a quickly detachable nearside front chassis member and associated body panels. Customer research and vehicle clinics identified this as an area vulnerable to accident damage, and hence the development of a design solution that offers quick and cost-effective repairs.

A further example is the revolutionary new fuel tank, shaped to parallel the stair profile, it allows more efficient body packaging, yet is more accessible formaintenance than a conventional tank.
