3-Door Enviro500 on road tests in Zhuhai

Published: 10 March 2021. Last update: 23 March 2021.

The 3-Door Alexander Dennis Enviro500 bus has been spotted undergoing road tests in Zhuhai.

In a recent video contributed to Land Transport Guru, the lush green 3-Door bus could be seen roaming the coastal roads west of Zhuhai Jinwan Airport (机场西路), a short distance away from ADL’s assembly facility.

The exterior features of the bus are very similar to the original artist impressions, featuring windowed staircases on the offside, and a single-leaf 3rd door on the nearside. 

The 3-door Enviro500 is powered by the Mercedes-Benz OM936 (Euro 6-compliant) engine. The bodywork styling is a facelifted design first introduced in 2015 and featured on the 3-door concept bus exhibited in 2016—but was not opted for in earlier production batch Enviro500 orders in Singapore.

Contrary to external appearances, the second staircase is not a forward-facing staircase, but a half-turn staircase at the tail end of the bus, similar in layout to the 3-door concept bus.

These are also the first Enviro500 3-door buses to be specifically designed for the right-hand-drive market. Under Contract PT342 (Procurement of 3-Door Euro 6 Double Deck Diesel Buses), Alexander Dennis Limited (ADL) will deliver 50 units to Singapore, with units likely to enter service this year (2021).

In-depth coverage of the bus model can be found within the dedicated bus model article: Alexander Dennis Enviro500 (3 Door).

Assembly in Zhuhai

All Enviro500 buses in Singapore (except for SMB5001A) are assembled in Zhuhai (Guangdong Province, China), where ADL buses are manufactured for the Asia-Pacific market.

The bus features a full-flat floor design along with three passenger doors and two staircases, one at the front and one at the rear of the vehicle, allowing commuters to move through the vehicle quickly and safely. It will also use the latest aluminium composite body technology and a host of new safety and energy-saving features.


Buses were prepared for shipment at the Zhuhai assembly plant in late March 2021, as seen in videos uploaded to Douyin.
