As part of the Bus Contracting Model, the Land Transport Authority (LTA) initiated further purchases of MAN A22 (or MAN NL323F) buses. These are the fourth batch of MAN A22 buses to be built for the Singapore market.

Contract PT337 – Procurement of 250 MAN Buses, which was awarded to ST Engineering Land Systems (previously Singapore Technologies Kinetics Ltd), consists of both MAN A22 and MAN A95 buses to Euro 6 specifications.

These buses are Euro-VI compliant and are bodied by Gemilang Coachworks with the MAN Lion’s City bodywork. Also in compliance with new LTA specifications, buses are equipped with a suite of new features, such as Passenger Information Display Systems (PIDS) and two wheelchair bays.

Singapore adopted the Euro 6 (or Euro VI) standards for all new diesel vehicles registered in Singapore from 1 January 2018, representing the latest in emission standards. As such, new buses which were registered from 2018 had to comply with the more stringent emission standards.

Buses are registered from SG1749E onwards. The first three buses were registered on 25 May 2018, leased to SBS Transit and made their revenue service debut on Express Bus Service 851e on 28 May 2018. In late June 2018, SG1752U – SG1755L were leased to SMRT Buses and made their revenue service debut on Bus Service 991 on 8 July 2018.

In late August 2018, SG1797R & SG1798M were leased to Go-Ahead Singapore. SG1797R made its revenue service debut on Bus Service 68 on 5 September 2018.

These MAN A22 buses are procured through a negotiated contract between the Land Transport Authority (LTA) and ST Engineering Land Systems, the authorised local dealer for MAN Trucks & Buses.

Since the start of the Bus Contracting Model (BCM), the LTA has assumed responsibility for the procurement of buses. Apart from Open tenders, the LTA previously purchased buses under negotiated contracts, such as 100 Mercedes-Benz Citaro buses, 176 Volvo B9TL buses, and 122 MAN A95 buses.

A projected combined intake of 250 Euro 6 MAN A95 and MAN A22 buses will be procured under Contract PT337, with an option for more MAN A95 Euro 6 Buses exercised.


New requirements imposed by the LTA for new buses include an enhanced Passenger Information Display System (PIDS) comprising LED text displays, LCD display screens and interior speakers. In addition, an exterior-facing display screen and an external speaker is included. An Advanced Driver Assistance System (ADAS), driver fatigue detection system, high-definition CCTV cameras, and passenger counters at entrance and exit doors of the bus are just some of the additional specifications required by LTA.

The buses are also equipped with 2 wheelchair bays. The Diesel-Hybrid buses (Volvo B5L Hybrid), Euro 6 Double Deck Diesel buses and Electric buses will also feature 2 wheelchair bays.


SG1800P was featured at the Singapore Business Night organized by ST Engineering Land Systems, held at Singapore Expo Hall 1 on 30th October 2018. It sported a “1000 Buses for Singapore” advertising wrap.


The exterior styling of the bus bears a mix of styling elements from previous and concurrently-produced batches of MAN A95 buses, such as the large grey stripe on both sides of the bus, and a large headlamp design likely inspired from MAN Trucks. The front bumper design, identical to that used on Euro 6 MAN A95 buses, have the fog lights removed.

These buses were bodied by Gemilang Coachworks of the MAN Lion’s City bodywork, licensed by MAN. However, unlike integral units of the MAN Lion’s City which have a distinctive design, the local units bear bodywork elements heavily borrowed from the MAN A22 buses previously procured for the local market. Furthermore, these buses do away with the curved roof attachment of the Lion’s City Hybrid specification (fitted entirely for aesthetic purposes), which had thus far been a distinctive feature of local MAN A22 buses.

The initial 55 buses (registered SG1749E – SG1803G) have a smaller EDS. Subsequent buses were fitted with a larger EDS on the front and rear.

The lower deck of the bus features 33 permanent seats. Being a low-floor bus, the bus offers step-free access from entry/exit doors until the last row of seats.

Like most single-deck buses in Singapore, the MAN A22 (Euro 6) buses are configured with two doors: an entrance door at the front, and an exit door in the middle. The entrance doors are conventional inward-swinging leaf doors, while the exit doors are outward-swinging sliding plug doors. They are supplied by Masats S.A. of Spain.

Seats were supplied by Vogel Industries of Malaysia (Model: System 750/3) in sky blue and grey, with priority seats in red. The front wheel arch seats, however, are formed with fabric laid down directly onto moulded bodywork panels. The seat covers are made of a high-friction PVC material that offers greater seating comfort over older bus seats.

As part of new LTA requirements, the bus features two wheelchair bays, both located opposite the exit door. They each accommodate one passenger-in-wheelchair (PIW), and are not equipped with USB charging ports.

Priority seats, which are indicated in red seat covers, occupy two rows of seats just ahead of the exit door.

Grab poles and hand grips are located on both sides of the aisle. All seats also have hand grips to provide commuters with additional support. Metal stanchion poles and handlebars, formerly finished with a smooth reflective coat, now bear a brushed metal finish similar to that earlier used on the 3-door MAN Lion’s City SD Concept Bus.

Bus stopping bell-pushes are located around the bus cabin, either mounted to stanchion poles or on the pillars in-between windows. Emergency hammers are also located on these pillars.

To accommodate the larger size of underfloor components (likely the MAN SCRT system), the seating area behind the left rear wheel is raised, similar to that of Mercedes-Benz Citaro buses.

Driver’s Compartment

The layout of the driver’s compartment is similar to previous batches of MAN A22 buses, with an updated steering wheel design. The yellow fare collection box has also been replaced with a turquoise one.

The turquoise display unit on the bottom left is the New On-board Bus Equipment (NOBE) fare collection system controller. To the right of the NOBE is the Trapeze Common Fleet Management System (CFMS) display unit. The gear selector, door controls and the handbrake lever are located on the right of the driver. A CCTV monitor, located above the driver, assists with monitoring of the surroundings. Air-conditioning and Electronic Display Sign (EDS) controllers are co-located with the CCTV monitor above the driver.

Also new to the MAN A22 (Euro 6) buses is the Driver Anti-Fatigue System as a requirement, with the camera unit and infrared illuminator installed on the top right of the dashboard. The unit is supplied by Seeing Machines.

Additional Features

MAN A22 (Euro 6) - USB charging port between seat pairs
MAN A22 (Euro 6) – USB charging port between seat pairs
USB Charging Ports

The bus is equipped with USB charging ports (with covers) for all seats, but not for the two wheelchair bays and their foldable seats. A single charging port has room for two USB cables, with an output of 1A and 2.1A.

The charging ports are located in the middle of every pair of seats for the benefit of both seat users. Previously, USB charging ports were mounted along the side panels of the bus, resulting in inconvenience for commuters in aisle seats wanting to use the charging port. For the pair of wheel arch seats located above the front axle, charging ports are located on the side.
