The MAN NG363F (A24) is a fully-low-floor, rear-engined articulated transit bus built by MAN Truck & Bus, with various units operating around the world.

Currently, SMRT Buses is the sole local public transport operator with the MAN NG363F, with a single demonstrator unit brought in for evaluation. 40 more units are expected to be brought in the first production batch.

Technical Information:

The MAN NG363F is part of the NG3X3 line of articulated bus chassis, assigned the model designation of A24. It was designed off MAN’s popular urban bus line, the Lion’s City, which was only available with integral bodywork by MAN. The NG363F is available with various bodywork designs from different manufacturers.

MAN NG363Fs come with the standard MAN D2066 LUH inline 6-cylinder, horizontally-mounted, turbocharged & intercooled engine, with a range of available power outputs of between 270 and 400 horsepower over Euro III to Euro V emission standards. A less powerful MAN E2876 EEV-rated engine is also avaliable with lower horsepower output. For the Euro V rating, 320hp, 360hp and 400hp versions are avaliable, along with a 2-stage turbocharger for high torque rating. The engine uses Exhaust Gas Re-circulation (EGR) technology and MAN’s own PM-Kat® exhaust treatment system to achieve its Euro V rating. CNG engines are also available.

For transmission, the MAN NG363F offers both Voith and ZF options along with the D2066 engine.

Like other bendy buses in Singapore, the MAN NG363F is a pusher bendy, meaning that the rear wheels provide the driving force from the engine. Both the middle and rear axle deploy a drop axle (also called an inverted portal axle) design to keep the chassis height low and allow for the full-low-floor design, which aids in passenger movement.

SMRT MAN NG363F A24 Demonstrator (MAN’s Lion City G / Gemilang) : SMB388S

In 2013, SMRT Buses received a MAN N6363F demonstrator unit for road testing and evaluation by MAN’s local dealer, ST Kinetics. The bus was registered on 2 Apr 2013 as SMB388S, the sixth demonstrator unit received by SMRT Buses.

SMB388S – Offside

SMB388S – Nearside

Basic Specifications:

  • MAN D2066 LUH-33 engine
    Turbocharged & Intercooled, 10518cc, 360 hp (265 kW) @ 1900 rpm
    Torque rating of 1600 Nm @ 1000 – 1400 rpm
  • Euro V-compliant
    Exhaust Gas Re-circulation (EGR) technology combined with MAN’s own PM-Kat® exhaust treatment system, hence doing away with the need for diesel exhaust fluids
  • Voith DIWA D864.5 gearbox
    Four-speed automatic.
  • Gemilang / Lion’s City G bodywork
    Chassis built in Germany, MAN’s Lion City G bodywork supplied and assembled by Gemilang Coachworks, licensed by MAN.
  • Spheros roof-mounted air-conditioning (Two units)
  • Gorba Imotion Electronic Display Signage (EDS)
    Orange LED Matrix, route details displayed on front and side EDS units

The bodywork used on this bus was similar to MAN’s Lion’s City G buses, but manufactured by Gemilang Coachworks of Malaysia, under license from MAN. Like other MAN buses, the chassis was built in Germany. They were then assembled by Gemilang in Malaysia before final delivery to Singapore. The design was standardized with the other MAN NL323Fs in SMRT’s fleet, giving it an exterior appearance of an elongated NL323F. Unlike the production batch A22s, this bus did not come with the large roof attachment.

Inside, the configuration is roughly similar to the Batch 2 NL323Fs, with identical grabpoles and comparable layout. SMRT retained the unique sliding plug doors supplied by Masats; the rear doors used in the existing MAN NL323Fs. A single wheelchair bay is located in the middle of the bus, and a manual wheelchair ramp is installed only on the middle door.

SMB388S made its revenue service debut on 18 April 2013, deployed on Service 190 between Choa Chu Kang and New Bridge Road. It has since been under SMRT’s Kranji Depot and made special appearances on a variety of bus routes, such as 61, 67, 106, 180, 188, 300, 302 and 700/700A.

The Legacy

SMB388S was acquired as a direct replacement for TIB838H, the very first articulated bus in Singapore, which was deregistered shortly before this bus entered revenue service. Breaking away with the tradition of registering buses in numerical order, the somewhat auspicious SMB388S registration bears resemblance to it’s predecessor.

The introduction of SMB388S is reminiscent of how TIB838H came about. TIB838H, a Mercedes-Benz O405G, was acquired by TIBS as a high-capacity version of the previously-introduced and highly successful Mercedes-Benz O405. Along with similarities in the chassis, bodywork was also very similar, both built by Hispano Carrocera. For SMB388S, the MAN NG363F chassis is a high-capacity version of the MAN NL323F chassis, and was also built to similar interior configurations as the previously-introduced and successful MAN NL323Fs.

SMB388S scored a few firsts. It was the first bendy bus to be brought in by SMRT Buses, and the first fully-low-floor and wheelchair-accessible bendy bus in Singapore. It is the second transit bus in Singapore to use Gorba EDS (after SMB136C and not including PA9588S), and the first transit bus in Singapore to have air-conditioning units supplied by Spheros.

Additional Specifications:

SMB388S has a licensed capacity for 130 passengers: 54 seating and 76 standing passengers.

SMRT MAN NG363F A24 Production Batch (MAN’s Lion City G / Gemilang) : SMB8001E – SMB8039Y

In April 2014, SMRT announced the further purchase of 40 more MAN NG363F articulated buses (including SMB388S). They would likely be acquired as a direct replacement for the initial 40 Mercedes-Benz O405G MkIs registered in 1997, namely TIB849B – TIB883B.

Technical specifications are roughly similar to the demonstrator; however the unladen weight of a production batch bus 16320kg, 160kg lighter than that of the demonstrator. Deliveries would commence in early 2015, to be delivered with SMRT’s new pixel livery.

The first production batch unit, SMB8001E was spotted in SMRT’s new pixel livery in Woodlands Depot in early Feb 2015. The bus was registered on 11 Mar 2015, and commenced revenue service on 15 March 2015, appearing on Service 190.

Basic Specifications:

SMB8001E on Service 190

  • MAN D2066 LUH-33 engine
    Turbocharged & Intercooled, 10518cc, 360 hp (265 kW) @ 1900 rpm

  • Euro V-compliant
    Exhaust Gas Re-circulation (EGR) technology combined with MAN’s own PM-Kat® exhaust treatment system, hence doing away with the need for diesel exhaust fluids
  • Voith DIWA D864.5 gearbox
    Four-speed automatic.
  • Gemilang / Lion’s City G bodywork
    Chassis built in Germany, MAN’s Lion City G bodywork supplied and assembled by Gemilang Coachworks, licensed by MAN.
  • Denso LD8u roof-mounted air-conditioning (Two units)
  • Mobitec MobiLED Electronic Display Signage (EDS)
    Orange LED Matrix, route details displayed on front and side EDS units. Uses a Mobitec MobiMASTER ICU 402 controller.

Production batch MAN A24 buses are deployed mostly on feeder and intratown bus services.

Clarifying the Differences: D2066 LUH-32 or LUH-33?

Both the LUH-32 and -33 engines are very similar; they are almost the same engine with minor differences in their engine control unit (ECU) which subsequently affect engine output. SMB388S exhibits many characteristics of weak output, but its engine need not have been tuned identically as a default -32, it could have just as well been a detuned -33. Not to mention that SMRT (and SBS Transit) frequently detune their buses to levels better suited for regular local operations (which saves on fuel and maintenance regimes).

Since LUH-33 has been the standard production engine for all NG363F chassis produced by MAN for years, there would be no reason to assume that SMB388S would be fitted otherwise.

20 thoughts on “MAN NG363F A24

    • Are you referring to SGWiki and other websites which use information from there? In which case they are probably wrong; we are highly certain about the engine and gearbox aspects of this bus.

    • I shall try my best to explain:

      The common misconception about SMB388S is its 360bph engine, which is assumed to be the LUH-33 engine of MAN’s D2066 engine line (which is coincidentally rated at 360bhp). In actual fact, SMB388S uses a LUH-32 engine similar to its MAN A22 rigid variants, but uptuned from 320bhp to 360bhp. The lower output torque of the LUH-32 (1600 N.m. versus 1800 N.m.) also results in its Voith D864.5 gearbox rather than the D884.5 gearbox as commonly assumed. This is because transmission options are chosen based on maximum torque output of the engine, and the D864.5 is produced for a lower maximum engine torque (1600 N.m.) as compared to the D884.5 (1900 N.m.)

      In short, SMB388S has an identical engine as its MAN A22 rigid variants, but uptuned to 360bph and fitted with a Voith transmission rather than ZF. Here’s a comparison:

      LUH-32: MAN A22 (MCV + Gemilang), MAN A24 Demonstrator (SMB388S)
      LUH-33: MAN A95 (SMB5888S), MAN A24 Production Batch (Very likely, but TBC)

      With SMRT well aware about the slow pickup issues plaguing SMB388S, likely due to the lower torque output and gearbox choice, the production batch MAN A24s will likely use the LUH-33 engine and a ZF gearbox, similar to SMB5888H.

      For your reference here are some figures from MAN and Voith:

      and a scan from SMRT’s quarterly newsletter:

      • It is Very unlikely to fit these Buses with ZF Ecolife 6 AP 2000B (A22 and Enviro 500 Uses ZF Ecolife 6 AP 1700B (Enviro 500 Uses ZF Ecolife 6 AP 1700 B with TopoDyn Life)) Like the A95 (SMB5888H), A22 (SMB189A-SMB354P, SMB1301K-SMB1567K, SMB1569E-SMB1581T, SMB3001M-SMB3116R), it may Likely to be Fitted with a Voith DIWA 884.5 Instead like the A22 Buses (These Buses Use Voith DIWA 864.5) (SMB1568H, SMB1582C-SMB1650R, SMB3117M-SMB3118K and SMB388H).

      • We would like to rebut our previous lengthy comment and retract our original assumption that SMB388S was fitted with a MAN D2066 LUH-32. After some research, we are more convinced that it is fitted with a MAN D2066 LUH-33 instead.

        Both the LUH-32 and LUH-33 are very similar, but the LUH-33 has been the standard production engine for all NG363F chassis produced by MAN for years. Furthermore, MAN only provides the ZF EcoLife 6AP 2000B or Voith DIWA 864.5 transmission as standard, and the engine will likely be tuned to pair well with the Voith gearbox despite the published torque limitations.

        As such, we believe that SMB388S is fitted with a LUH-33 engine but tuned very similarly to a MAN A22 (with the less powerful LUH-32 engine), which is the fault of either the dealer (ST Kinetics) or the operator (SMRT). This may explain the slow acceleration and constant low rpm that the bus constantly operates at.

        SMRT’s quarterly newsletter? Well, there’s a good chance that they might be wrong too. They had published the Mercedes-Benz O405G with the OM447hA engine instead of the OM447hLA.

        Yep.

  1. Dear FR,

    An production batch A24 has been delivered and painted in the new SMRT pixel livery in Woodlands Depot. Do be patient as the bus has yet to receive and register its registration plate as well as undergo further training with bus captains.

  2. Service like 187, 966 and 67 will not get MAN NG363F as they already had Alexander Dennis Enviro 500 that is also high-capacity buses.
