Just to clarify on the history about the Transbus/Alexander
Dennis Enviro 500 buses.
When Transbus International was formed after the merger in 2001,
the old Dennis Trident 3 was still sold under the Dennis brand. In
2002, Transbus annouced the development of a new chassis based on
the Trident 3, which is the Enviro 500.
This is the Transbus Enviro 500 (which is still badged a
Dennis):
In 2004, Transbus became Alexander Dennis Limited, and the
Enviro 500 received a new facelift and the Dennis badge was changed
to Alexander Dennis:
In 2012, Alexander Dennis unveiled a new generation of the
Enviro 500 chassis and a new facelift design based on the Enviro
400. This chassis is known as the Enviro 500 NG (New generation) or
the Enviro 500 MMC (Major model change):

What SMRT ordered could be known as the Enviro 500 NG or the
Enviro 500 MMC, both mean the same.
