The Scania K230UB (K-Series 230-bhp Urban Bus) is a low-entry wheelchair-accessible single-deck transit bus built by Scania AB. Commonly referred to as the “KUB“, the chassis is manufactured in Europe, and the bodywork supplied by Gemilang Coachworks of Malaysia.

Currently, Singapore’s major bus operator, SBS Transit, is the largest local operator of Scania K230UBs in Singapore, with over 1000 vehicles. First introduced in 2007, this was the largest order of any single model of transit bus in Singapore, until the record was broken by the Volvo B9TL.

Other operators of the Scania K230UB include Singapore Ducktours, WTS Travel, Comfort DelGro (operating as National University of Singapore shuttle buses) and Resorts World Sentosa.

Technical Data:

There are two major variants of Scania K230UBs in Singapore, the Euro IV and the Euro V. Both fulfill the requirements of the Euro IV / V and EEV emissions standards using Exhaust Gas Recirculation (EGR) technology, which does not require diesel exhaust fluids unlike SCR.

The low entry design incorporates zero-step access at the entry and exit doors, allowing for disabled access and more convenient boarding and alighting. This is achieved by relocating various components to the rear of the bus.

Gemilang Coachworks Sdn Bhd of Malaysia supplies the bodywork for the Scania K230UBs of SBS Transit. Buses are assembled by a mix of ComfortDelGro Engineering, Gemilang Coachworks and SC Auto.

In Summary:

The Scania K230UB is a familiar bus model in Singapore. SBS Transit acquired one demonstrator unit in 2007, followed by 1100 more units of production batch buses between 2007 and 2010. The first 500 were of the Euro IV specification, while the remaining 600 were of the Euro V specification. All were fitted with ZF 6HP504C transmissions and bodied by Gemilang Coachworks of Malaysia.

The intake of Scania K230UBs were, at the time, the largest intake of any bus model in Singapore. They were acquired as a direct replacement for the retiring Scania N113CRBs, Volvo B10M Mark IIs, and Mercedes-Benz O405s. All KUBs are of the low-entry configuration, with a manual wheelchair ramp at the rear doors.

Demonstrator Unit (SBS8033D):

In 2006, SBS Transit launched its first wheelchair-accessible bus, the double-deck Volvo B9TL bodied by Comfort DelGro Engineering. With the upcoming retirement of the Volvo B10M MkIIs, Scania N113CRBs and Mercedes-Benz O405 CACs, there was a need to bring in more wheelchair-accessible single-deck buses to replace these older models, and at the same time, meet with more stringent vehicular emission requirements set by government agencies.

In 2007, SBS Transit received a prototype Euro IV Scania K230UB for demonstration and evaluation purposes. The bus was registered on 19 Oct 2007 as SBS8033D, following the line of 803X-registered demonstrator buses.

SBS Transit’s Scania K230UB demonstrator

Basic Specifications:

  • Scania DC9 16 230 engine
    – In-line 5-cylinder (fixed-geometry) turbocharged, 8867cc
    – 230 hp (169 kW) @ 1800 rpm
    – Torque rating of 1050 Nm @ 1100 – 1500 rpm
  • Euro IV compliant
    Exhaust Gas Recirculation (EGR) Technology
  • ZF Ecomat 6HP 504C gearbox
    Six-speed automatic
  • Gemilang Bodywork
    Chassis built in Europe, bodywork designed, supplied and built by Gemilang Coachworks of Malaysia.
  • CoolAir Electronic Destination Signages (EDS)
    Orange LED matrix design.
  • Carrier Sütrak AC 353 air-conditioning, roof mounted

Bodied by Gemilang Coachworks, the bus originally had a unique front design with grill above the license plate and larger headlights versus the production batch. The Electronic Destination Signage (EDS) was supplied by CoolAir, which would become standard in the subsequent production batch. In August 2013, SBS8033D had its entire front replaced with a Euro V KUB design after an accident.

The demonstrator is fitted with the Scania DC9 16 230 turbocharged engine which would be standard across buses of the Euro IV batch. The six-speed ZF 6HP 504C gearbox used is standard for the Scania K-Series and will be used in all K230UBs following the demonstrator unit. Inside, there are two bays for Passengers-in-wheelchair (PIW), with a manual ramp located at the exit door. Seats are supplied by Volgelsitze (System 400). The interior is purple-themed, intended to fit in with SBS Transit’s corporate colours. There are no wheelarch seats (“granny seats”) available, a feature which was consistent with the first batch of Euro IV K230UBs.

Unlike other demonstrator units, SBS8033D entered revenue service along with the production batch of its model.

Additional Specifications:

In August 2013, SBS8033D had its front replaced with a Euro V KUB-design after an accident.

SBS Transit Euro IV Batch 1 (SBS8034B – SBS8131D, SBS8138K & SBS8888D):

SBS Transit purchased 500 Scania K230UBs of the Euro IV specification in 2007. Built at a cost of $180 million, the 500 single-deck buses boast environmentally friendly Euro IV engines which emit fewer harmful particulates into the atmosphere. In addition, exhaust gas re-circulation technology (EGR) is employed to cleanse the fumes that are emitted. The buses are also made with special high tensile, lightweight material, and equipped with six-speed ZF automatic transmission to improve fuel efficiency.

Out of the 500 new buses, 100 of them were built under the Batch 1, with similar technical specifications to the demonstrator unit. They were registered in late 2007 as SBS8034B – SBS8131D, SBS8138K & SBS8888D.

Scania K230UB – Euro IV Batch 1

Basic Specifications:

  • Scania DC9 16 230 engine
    – In-line 5-cylinder (fixed-geometry) turbocharged, 8867 cc
    – 230 hp (169 kW) @ 1800 rpm
    – Torque rating of 1050 Nm @ 1100 – 1500 rpm
  • Euro IV compliant
    Exhaust Gas Recirculation (EGR) Technology
  • ZF Ecomat 6HP 504C gearbox
    Six-speed automatic
  • Gemilang Bodywork
    Chassis built in Europe, bodywork designed and supplied by Gemilang Coachworks of Malaysia. Final assembly by Gemilang Coachworks and ComfortDelGro Engineering.
  • CoolAir Electronic Destination Signages (EDS)

  • Denso LD8i or LD8u air-conditioning, roof mounted

SBS8138K and SBS8888D belong to this batch, although they do not follow the numerical registration order of this batch. The “8888” registration was presumably done to follow-up with other demonstrators such as SBS9888Y and SBS9889U. On 01 Nov 2007, these buses made their debut on Service 100 (between Serangoon and Ghim Moh), and Service 174 (between Boon Lay and New Bridge Road).

These buses carried a beige and red-themed interior in contrast to SBS8033D. Seats were also supplied by Vogelsitze, but of the System 750/3 make.

Additional Specifications

  • The bus has a licensed carrying capacity of 87 passengers, comprising 29 seated and 58 standing passengers. Two wheelchair bays are available.
  • Some of these buses have been SPAD registered for use on cross-border routes (160170 and 170X).
  • Some units are installed with Denso LD8u air-conditioning units
  • Large numbers of them are also based at Hougang Depot for bus driver training.

SBS Transit Euro IV Batch 2 (SBS8132B – SBS8561X, with unused registration numbers):

Out of the 500 new Euro IV Scania K230UB buses, 400 of them were built under the Batch 2, with similar technical specifications to the Batch 1. They were registered between 4 Apr 2008 and 15 Jan 2009 as SBS8132B – SBS8561Xwith unused registration numbers in between, such as those with the number “4” in the third and/or fourth digit.

Scania K230UB – Euro IV Batch 2

Compared to the Euro IV Batch 1 buses, the Batch 2 has a slightly different placement of grab poles. A granny seat (for one adult and one child only) was fitted behind the driver’s cabin. Final assembly was done by ComfortDelGro Engineering and SC Auto.

Additional Specifications

  • The bus has a licensed carrying capacity of 88 passengers, comprising 30 seated and 58 standing passengers.. Two wheelchair bays are available.
  • Some of these buses have been SPAD registered for use on cross-border routes (160170 and 170X).
  • In 2010, SBS8405P received a full LECIP EDS set, but reverted back to CoolAir in 2011.
  • Some units are installed with Denso LD8u air-conditioning units

Basic Specifications:

  • Scania DC9 35 230 engine
    – In-line 5-cylinder (variable-geometry) turbocharged, 9290 cc
    – 230 hp (169 kW) @ 1900 rpm
    – Torque rating of 1050 Nm @ 1000 – 1500 rpm
  • Euro-V compliant
    Exhaust Gas Recirculation (EGR) Technology
  • ZF Ecomat 6HP 504C gearbox
    Six-speed automatic
  • Gemilang Bodywork
    Chassis built in Europe, bodywork designed and supplied by Gemilang Coachworks of Malaysia. Final assembly by ComfortDelGro Engineering, SC Auto and Gemilang Coachworks
  • Hanover Electronic Display Signages (EDS)
    Orange LED matrix design.

These buses operate on exhaust gas re-circulation technology (EGR) to achieve the higher Euro V emission standards, made with high tensile and lightweight materials, and equipped with six-speed ZF automatic transmission similar to previous batches. Hanover Electronic Destination Signage (EDS) was fitted for clearer displays, which make them easily distinguishable from their Euro IV cousins.

Compared to the Euro IV buses, the Euro V K230UBs have an additional granny seat (for one adult and one child only) above the left wheel-arch, just behind the front entrance door (hence a total of two granny seats). Each bus has only one wheelchair bay; the other was converted into longitudinal seating for three to accommodate more seating passengers.

Additional Specifications

  • The bus has a licensed carrying capacity of 87 passengers, comprising 34 seated and 53 standing passengers. One wheelchair bay is available.
  • SBS8689L is fitted with front and rear doors by Masats, similar to those used on SMRT’s MAN A22s

Scania K230UB – Euro V Batch 2

These batch of buses are identical to the previous Euro V Batch 1 buses, in technical specifications and interior configuration, and can be seen as an extension of the Euro V batch. There are no differences in specifications between these two batches of buses. Hanover Electronic Destination Signage (EDS) was fitted for clearer displays, which make them easily distinguishable from their Euro IV cousins.

Buses in this batch were fully assembled by ComfortDelGro Engineering.

During the 2010 Youth Olympic Games (YOG) in Singapore, 38 Euro V Batch 2 Scania K230UB was chartered out to ferry athletes within the YOG Village in NTU. These buses bore a special YOG livery and registration numbers YOG2141 – YOG2177.

Additional Specifications

  • The bus has a licensed carrying capacity of 87 passengers, comprising 34 seated and 53 standing passengers. One wheelchair bay is available.
