All three options in the ADI product line-up — transit, commuter and open-top — are set to benefit from a stunning new look that will be progressively rolled out over the next 18 months, including vehicles that will form part of significant new transit orders likely to be announced in New Orleans.

The striking new appearance comes on the back of fleet sales in recent years to Vancouver, Toronto, New York, Las Vegas, San Francisco, Washington, D.C. and Seattle, all of which have carved out a unique place for ADI double-decks in the transport landscape of North America.

And, adding to the appeal of their high-capacity, three-axle Enviro500 models, ADI is also set to announce plans for a new, low-height, "go anywhere" double deck range.

These buses will have the same carrying capacity as existing models (around 100) and retain the maneuverability that has made the Enviro500 a big favorite with drivers — but, equally important, by virtue of their reduced height they will open up a raft of new route options across the U.S. and Canada, according to the company.

All ADI double-deck products are fully Buy America Compliant.
