Mechanically, the configuration of the production MAN NL323F (coded A22) is similar. Its Exhaust Gas Recirculation (EGR) and PM-Kat filter technology (the latter developed by MAN) does away the need for additives in exhaust treatment, while still able to meet the Euro V emission standards. It is powered by the MAN D2066LUH-32 diesel engine (10,518cc) and fitted with 6-speed ZF Ecolife 6AP 1700B automatic transmission.
The bodywork supplied by Gemilang gave the production batch NL323Fs a very different appearance. The exterior design was roughly based on the integral 'Lion's City Hybrid' seen in European countries, but it was neither named as such nor was it a electric-hybrid bus. The unique protruding roof design, which covered the Denso overhead air-conditioning pod, has led to a number of hilarious nicknames given by both the public and bus enthusiasts.
EDS was supplied by Mobitec, which included additional route details on the boarding side of the bus. The interior configuration and design was fully low-floor and similar to the demonstrator NL323F; sliding plug-doors were fitted at the exit for additional safety. The first production NL323F entered service on service 963 (Woodlands to HarbourFront) in September 2011. Batch One units were registered SMB189A to SMB354P.
