Scania K-series is a series of bus with longitudinally, straight-up mounted Euro IV engine at the rear. For the 5- and 6-cylinder engines Scania is using exhaust gas recirculation (EGR) system to fulfill the legal Euro IV emission standard. The K-series is available with 9-litre 5-cylinder engines with output of 230 hp (1050 Nm), 270 hp (1250 Nm) or 310 hp (1550 Nm) as well as the 12-litre 6-cylinder engines with output of 340 hp (1700 Nm), 380 hp (1900 Nm), 420 hp (2100 Nm) or 470 hp (2200 Nm).
With Euro 5 emissions becoming mandatory in Europe in 2009, Scania have released upgraded engines in order to meet these regulations. The 5-cylinder DC9 engines feature a larger bore and displace 9.3-litres instead of 8.9-litres. The DC12 engines feature both a larger bore and a longer stroke, and therefore displace 12.7-litres instead of 11.7-litres. Most engines also receive slight performance improvements, for example the DC9 engine that outputs 310 hp/1550 Nm has been upgraded to 320 PS/1600 Nm.
The variants of K-series bus include coach, intercity bus and citybus chassis.
The K-series replaced the K94, K114, K124 and the L94 series (with the 60 degrees inclined-engine).

SBS Transit
In early 2007, SBS Transit purchased 500 K230UBs[1] at a cost of S$180 million, as part of its scheme to replace its aging Volvo B10M MK2, Scania N113CRB & Mercedes-Benz O405 fleet and compliance with the new Euro 4 emission standards set by local authorities.[2] The single-deck buses are wheelchair accessible and have 2 wheelchair bays each. They are also fitted with 6-speed ZF automatic transmission as well as Cool-Air electronic destination signage (EDS), and were bodied by Gemilang Coachworks of Malaysia with a modified Scania licenced front.
Two services, Service 100, plying between Serangoon and Ghim Moh, and Service 174, plying between Boon Lay and New Bridge Road, became the first two services to operate these buses when introduced onto service on Thursday, 1 November 2007. As of January 2009, deliveries and introduction into service of the first 500 orders have been completed. They were registered in two batches, the first batch being SBS8033D to SBS8131D, SBS8138K and SBS8888D; the second batch being SBS8132B to SBS8561X (excluding SBS8138K). SBS8033D is a demonstrator in the fleet and is currently deployed under Soon Lee depot to operate on Service 183. The registration series for the second batch of buses, however, does not include those ending with the number 'four' for buses registered after 9 June 2008. SBS8214Z and SBS8474P were the last two buses to be registered with the number 'four'.
In mid-2008, SBS Transit purchased another 400 K230UBs at the cost of S$147 million, with similar features to the first batch of 500. However, the 400 new orders came configured with a Euro V engine as standard, one wheelchair bay each in favor of extra seating, and a bigger Hanover EDS. The first of these buses were registered from March 2009; registration series began with SBS8562T and later, SBS8875R. The first few units of Euro V Scania K230UBs were first deployed on Services 3 and 36 in April 2009. Ironically, the number 'four' series were introduced back into the registration series in mid-2009 for buses registered from SBS8875R onwards.
SBS Transit made a further order for 200 more K230UBs in August 2009 at S$72 million, with deliveries targeted to begin from November 2009 onwards till 2010. These new additions are likely to have the same specifications as the batch of 400 Euro V K230UBs currently being introduced into service.
Singapore Ducktours
Singapore Ducktours has 3 Scania K230UBs, configured as open top double deckers with bodywork by Soon Chow Corporation for its Hippotours service.

The twenty 10.6m versions of K230UBs have been registered between April and June 2009 and known as the ASB class. 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.

K310UD

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. [3]
