The next-generation Enviro500 is an all-new, lighter, and more fuel efficient high capacity double deck bus that has been designed specifically for the Asia Pacific market.

In developing the new Enviro500 ADL has focussed on bringing to market a double deck that raises the bar in terms of fuel efficiency, reliability, maintainability and best-in-class whole life costs. It combines anall new chassis with a new body and it has been designed as a fully integrated ADL product combiningpassenger safety and comfort.

The bus not only provides seats for 90 passengers but is future proof in terms of impending legislation. Initial vehicles are certified at Euro5 emission level, but the design can accommodate forthcoming Euro6 legislation and also has the ability to adapt easily from conventional diesel power to future hybrid or full electric drivelines.
