SMRT Buses of Singapore received a 12.0m MCV Evolution-bodied NL323F demonstrator in 2010 for evaluation, registered as SMB138Y. Following a successful trial, SMRT Buses placed a follow-up order of 200 buses through ST Kinetics, the largest order of NL323Fs at that time. These production batch buses were bodied under licence by Gemilang Coachworks with the bodywork design based on the MAN Lion's City Hybrid, and entered service on 2 October 2011. In 2013, SMRT Buses placed an additional order for 202 buses with similar specifications as the first batch of buses, with minor differences in the seating configuration for later buses. A further order of 332 buses was made in 2014, with largely similar specifications as the earlier buses.
As part of the Bus Contracting Model (BCM), some of the buses were transferred to Tower Transit Singapore, Go-Ahead Singapore and SBS Transit under the Bulim, Loyang and Seletar Bus Packages respectively. All of these buses have since been repainted into the lush green livery. The last 26 buses to be registered from the order of 332 buses were also painted into the lush green livery prior to entering service.
In October 2016, a MAN NL323F concept bus with 3 doors was exhibited at the Singapore International Transport Congress and Exhibition (SITCE). Marketed as the MAN Lion's City SD 3Dr, it features a modified bodywork design based on the MAN Lion's City Hybrid, built to a low-entry configuration under licence by Gemilang Coachworks. The bus was later painted into the lush green livery and began a 6-month trial service with SMRT Buses from 19 June 2017, starting from bus service 190.
