Chronology
Predecessor	Scania 4 series

The Scania K series is a series of chassis in Scania's city bus and coach range with longitudinally, straight-up mounted engine at the rear, replacing the K- (K94, K114, K124) and L-type (L94) chassis of the 4 series. The K series was first presented on Busworld 2005 in Kortrijk, Belgium, and models were available from 2006.

Type designation breakdown

Plant at which the vehicle was assembled (integral buses only)

C: former Kapena plant, Slupsk, Poland (K UB, K UA)
L: Lahden Autokori plant, Lahti, Finland – Interlink and OmniExpress (K UB, K IB, K EB)
T: Higer plant, China – A30 and A808 Touring coaches (K EB chassis only)

Engine location

K: chassis with centrally mounted longitudinal engine behind rearmost axle

Power code

Approximation of the power rating in hp to the nearest ten. The power code has spaces on both sides.

Type of transport

E: coach, long distance, high comfort
I: intercity, short to long distance, normal comfort
U: urban, short distance, normal comfort

Chassis adaption

A: articulated bus
B: normal bus
D: double-decker bus

Wheel configuration

4x2: two-axle bus
6x2: tri-axle bus
6x2/2: tri-axle articulated bus
6x2*4: tri-axle bus with steered tag axle
8x2: quad-axle bus (K IB in Latin America only)

K230UB4x2LB would be a two-axle "low entry" city bus, while K480EB6x2*4NI would be a tri-axle long-distance coach with a steerable tag axle.

Note: One might think that double-decker coaches are designated as (e.g.) K 440 ED6x2*4NI. But they still use K EB for some reason.

Engines

When introduced, the K series was available with Euro IV-compliant 8.9-litre (8867 cc) 5-cylinder engines (DC9) with output of 230 hp (1050 Nm), 270 hp (1250 Nm) and 310 hp (1550 Nm) as well as the 11.7-litre (11705 cc) 6-cylinder engines (DC12) with output of 340 hp (1700 Nm), 380 hp (1900 Nm), 420 hp (2100 Nm) or 470 hp (2200 Nm), the latter being a DT12 turbo-compound engine. For the 5- and 6-cylinder engines Scania is using exhaust gas recirculation (EGR) and selective catalytic reduction (SCR) systems to fulfill the legal Euro emission standards.

In 2008 Scania released upgraded Euro V engines in order to meet these regulations. The 5-cylinder DC9 (later DC09) engines featured a larger bore and displace 9.3-litres (9291 cc) instead of 8.9-litres. The new DC13 engines feature both a larger bore and a longer stroke and therefore displace 12.7-litres (12742 cc) instead of 11.7-litres. Some engines also received slight performance improvements, for example the DC9 engine that outputs 310 hp (1550 Nm) was upgraded to 320 hp (1600 Nm).

With the introduction of Euro VI engines in 2013, the DC09 outputs 250 hp (1250 Nm), 280 hp (1400 Nm), 320 hp (1600 Nm) and 360 hp (1700 Nm), while the DC13 outputs 410 hp (2150 Nm), 450 hp (2350 Nm) and 490 hp (2550 Nm). Euro III, IV and V engines are still available for export markets.

For alternative fuels, the 9.3-litre was available as the OC9 CNG engine with power outputs of 270 hp (1100 Nm) and 305 hp (1250 Nm), which from the introduction of Euro VI was replaced by the OC09 with power outputs of 280 hp (1350 Nm) and 340 hp (1600 Nm). The 8.9-litre is available as the ethanol fueled DC9 E02 with a power output of 270 hp (1200 Nm).

After undergoing tests, the first few units were finally introduced on route 2C plying between Yau Yat Tsuen and Tsim Sha Tsui on Sunday, 24 May 2009. Some other buses have also been introduced on suburban routes, such as route 7M & 24.

The ten 12m versions of K230UBs have also been registered between June and August 2009 and known as the ASC class.

A further 20 K230UBs of 12m length were ordered afterwards, with one being a Euro V EEV demonstrator of the ASCU class.

HZMB bus operator has ordered 100 K250UBs with Higer body and delivered in 2018.

Indonesia

In 2016, the Jakarta Provincial Government placed orders for 150 Scania K250UB Euro III to replace aging Kopaja and MetroMini fleet. In advantage of the older buses, the Scania K250UB is wheelchair accessible and fitted with air conditioner. It is also expected to reduce air pollution since it fulfills Euro III emission standard. The buses are operated by TransJakarta as MetroTrans, and operated outside the BRT system. Operation started by 2017.

In 2020, Suroboyo Bus purchased eight Scania K250UB Euro III buses bodied with Cityline 3 by Laksana. These units are equipped with bike racks in the front of the bus.

Malaysia

Rapid Bus, a Prasarana Malaysia subsidiary company, currently operates one of the largest fleets of Scania K-series buses, with a total of 830 single-deck K250UB and K270UBs with three different service brands.

They were assembled by Deftech using complete knock-down kits (CKDs) manufactured by Gemilang Coachwork.

In New Zealand, several operators have Scania K-series UB urban buses. Because of the additional weight of the 9-litre engine compared to the 7-litre units offered by other manufacturers, many (though not all) Scania urban buses are specified as 6x2 rather than 4x2. This helps reduce the operator's liability for road user charges, which are calculated by vehicle weight. Scania K-series urban buses may have tag axles at lengths where buses of other makes would not, e.g. NZ Bus's 2100 and 2200 series at approximately 12.0 m and only 42 seats.

Scania K-series urban buses pioneered steerable tag axles in New Zealand, which became a requirement for buses between 12.6 m and 13.5 m in length. Because Scania K-series buses had a longer rear overhang than competing makes, the allowable overhang with a steerable tag axle was increased from 4.25 m to 4.5 m. The Scania K280 UB 6x2*4 and K320 UB 6x2*4 have been popular chassis for operators building high-capacity single-deck buses. New Zealand's first double-deck bus in regular urban service was a Gemilang-bodied Scania K310 UD 6x2*4.

Singapore

SBS Transit and SMRT Buses

Euro IV

Euro VScania K230UB operating under SBS Transit in Singapore

SBS Transit placed orders starting in 2007 for the largest fleet of Scania K-series buses in Singapore, with a total of 1,101 Scania K230UB of both Euro IV and Euro V specification.

The company made its first purchase of 500 K230UBs at a cost of S$180 million in early 2007, as part of its scheme to replace most of the ageing fleet and compliance with the new Euro IV emission standards set by local authorities. The single-decker buses are wheelchair accessible and have 2 wheelchair bays each. They are also fitted with 6-speed ZF automatic transmission, and were assembled in Singapore by ComfortDelGro Engineering and SC Auto, using complete knock-down kits manufactured by Gemilang Coachwork of Johor, Malaysia. These buses featured a modified Scania licensed front.

In September 2008, SBS Transit purchased another 400 K230UBs at the cost of S$147 million, with similar features to the first batch of 500. However, these buses had Euro V EEV engine as standard, one wheelchair bay each in favour of extra seating.

SBS Transit made the last order for 200 more K230UBs in August 2009 at a cost of S$72 million.

In March 2024, LTA leased out 10 K230UBs from SBS Transit to SMRT Buses and in August and September 2024, 39 more K230UBs were leased to SMRT Buses as part of the Jurong West Bus Package.

Withdrawal

SBS8900B was involved in an accident in 2011 and was scrapped in 2013. The nature of the accident remains unknown.

With the mass influx of surplus buses to SBS Transit for revenue service in November 2021, 97 units of Euro IV K230UBs were taken out of revenue service to be scrapped progressively from January 2022 with the majority of them were APAD-registered and from Ulu Pandan Bus Depot. Like the case of Volvo B10M buses in 2014, these were replaced by newer buses such as Mercedes-Benz O530 Citaro and MAN NL323F single decker buses for cross-border bus services. 20 of these buses were stored at a warehouse in Keppel to be converted into a hotel resort (later known as The Bus Collective) at Changi Village, with the remaining scrapped by July 2022. Similarly, with the mass influx of BYD BC12A04 single deckers, 12 Scania K230UBs will be taken out of revenue service to be scrapped progressively from October 2024. All the remaining K230UBs will be extended for two years due to insufficient delivery of electric buses.

SBS8337C was involved in a collision with a trailer truck in February 2023 along the Seletar Expressway (SLE). The bus driver was trapped in his seat and had to be extricated by firefighters. The bus was scrapped in October 2023.

SBS8743M caught fire along Braddell Road in March 2023. The bus was damaged beyond repair and scrapped in October 2023.

SBS8142Y was involved in a collision with a lorry and a car along Yio Chu Kang Road while plying service 163. The bus was scrapped in October 2023.

SBS8849S was taken out of service and re-registered as PD1545C as a private bus under SBS Transit on 13 October 2023, and was converted to the SBS Transit CARES Community Bus. The bus was intended to support SBST's community outreach efforts, and was launched by Acting Minister for Transport Chee Hong Tat on 4 November.

Other operators

Singapore Ducktours has 9 Scania K230UBs (3 under 2007, 4 under 2010 and 2 under 2011), configured as open top double-decker buses with bodywork by Soon Chow Corporation for its Hippotours service. All buses were repainted into Big Bus Singapore livery starting from September 2018. They will all be replaced by Wright StreetDeck Electroliner open-top buses from 2026.

Singapore Changi Airport contracted Woodlands Transport Service Pte Ltd to operate 3 Gemilang-bodied Scania K230UB for its internal shuttle services (Budget Terminal >> Terminal 2). Upon withdrawal of the shuttle services (due to the closure of Budget Terminal), these buses were repainted into SATS gateway livery and are used inside the Airport runway.

Resorts World Sentosa operates a handful of KUBs to provide shuttle services for its hotel guests. These buses were bodied by SC Auto in a coach configuration.

National University of Singapore

Sentosa IslandSC Auto-bodied Scania K230UB operating under ComfortDelGro Bus

ComfortDelGro Bus also operates a handful of SC Auto-bodied K230UBs, purchased for the National University of Singapore internal shuttle service. Following retirement from NUS duties, these have been repainted and redeployed to other locations such as Sentosa. These buses were scrapped by 2023 and were replaced by the Volvo B9L.

Taiwan

Two units of Scania K230UB have been in operation by Ho-Hsin Bus (zh) in Tainan City since 2014, with bodywork by Gemilang Coachworks.

Uruguay

Two K270UB4x2LB with automatic ZF gearboxes chassis were bought by capital city Montevideo's urban and suburban bus operator UCOT (Union Cooperativa Obrera del Transporte/Cooperative Worker Union of Transport) and bodied in Brazil with Marcopolo Gran Viale LE bodywork in 2011 as testing units for a potential mass buyout of units in an incumbent partial fleet renovation arriving in July of that year. They were numbered 24 and 36 in sustitution of two Volvo B58E Caio Vitoria buses and assigned exclusively to the 300 line (UCOT most used line) but were finally deemed too powerful and expensive to operate in Montevideo, resulting in these two units becoming unique in the cooperative.

Scania K UD

The K280UD, K310UD and K320UD is the double-decker city bus variant with an 8.9-litre DC9-18 5-cylinder 310 hp Euro IV compliant engine (hence the 310 in K310UD), or a 9.3-litre DC9-29 5-cylinder 280 hp Euro V compliant engine. The 'U' indicates the bus is designed for the urban application, the 'D' points out the chassis is made for a double-decker.

Hong Kong

Kowloon Motor Bus of Hong Kong received two Scania K310UD (complete designation: K310UD6x2EB. The 6x2 shows the bus has a rigid bogie) buses with and ZF 6HP602 gearbox, the rear drive axle has a ratio (differential) of 6.20 and is also a product of ZF. The bus was designed in close co-operation with the body constructor Salvador Caetano (Waterlooville) in order to save weight.

The first one has been registered as MT6551 in March 2007 and entered service on route 104 in August 2007 after testing. The second one has been registered as NE6817 and entered service on route 69X in February 2008.

The K310UD6x2EB is the replacement of the unique K94UB6x2/4LB and also the second type of Scania double-decker bus (the first type is the Scania N113) for KMB.

KMB later ordered a further 20 more units of the K310UD in 2009, they were registered in January 2010.

ASU1 and ASU2 were de-registered in March 2012 and were shipped back to Sweden afterwards.

In March 2011, Citybus received one Scania K280UD (complete designation: K280UD6x2EB) tri-axle double decker. This is the second Scania bus acquired by Citybus, about 10 years after the unique K94UB6x2/4LB was introduced in 2001 (fleet no. 2800). It is equipped with a Euro V compliant Scania DC9-29 engine, rated at 280 hp with maximum torque 1400Nm, both of which are lower than the KMB counterparts (310 hp power output with 1550Nm maximum torque), coupled to a ZF Ecomat 4 6HP604 NBS 6-speed gearbox. It is also bodied by Salvador Caetano, but with some minor changes from KMB ones.

KMB also received two Scania K280UD buses in late 2014 with newly designed Salvador Caetano bodywork. These two buses, like the one purchased by Citybus, are also equipped with Euro V compliant Scania DC9-29 engine. These two buses feature orange Hanover LED destination signs and uses high capacity layout with square staircase. The first bus has been registered as TE7277 with the fleet code ASUD1 in February 2015, with the second one registered as TF6087 with fleet code ASUD2 in March 2015.
