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 2005Scania at Busworld 2005: New range of Scania buses and coaches Scania 20 October 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 H: Hybrid electric, 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) 8x2/2: quad-axle articulated bus (K IA only)

Chassis height L: low front, normal rear M: low front and middle, normal rear (K UA only) N: normal front and rear

Suspension B: air suspension front and rear, rigid front axle I: air suspension front and rear, independent front suspension

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).Scania at Busworld 2013 in Kortrijk, Belgium Scania 17 October 2013 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) 320 hp (1500 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).

Scania formally introduced the K-series chassis to the Philippine market in the mid-2010s through its authorized distributor, BJ Mercantile, Inc. The initial unit made available was the Euro 3 variant of the K360IB, which was first acquired by P&O Transportation and equipped with a Marcopolo Audace body. In the latter part of 2021, the Euro 5 version of the K360IB was launched, and by the fall of 2022, Bicol Isarog Transport System serving as the initial customer with 18 units.These units were fitted with bodies manufactured by Del Monte Motors. Concurrently, Scania unveiled the K400IB paired with its flagship Scania Touring body. This model was procured by Cagsawa Travel and Tours and by Elavil Tours Philippines, Inc., the latter of which further augmented its fleet in K360 units utilizing Del Monte-built bodies.

The subsequent year marked significant adoption in Northern Luzon, led by GV Florida Transport, which procured the K360IB in 2024. This acquisition positioned GV Florida Transport as the largest operator of Scania buses in the Philippines. The company’s initial fleet utilized bodies supplied by Del Monte Motors; however, later batches of K360 chassis were integrated with bus bodies produced by Pura Bus, the operator’s in-house bus body manufacturing division. Genesis Transport, operating under the Joybus brand, also incorporated K360IB units into its fleet, configured with Marcopolo Paradiso bodies.

In 2025, Scania introduced the K410CB as the official successor to the K360IB. GV Florida Transport once again emerged as a launch customer, further solidifying its role as a key partner in the continued expansion of Scania’s presence in the Philippine bus market.
