Proven and reliable powertrains with low exhaust
Scania engines, gearboxes and axles are renowned for their performance
and driver appeal, as well as their long and trouble-free service life.
Scania’s new truck range follows this tradition with a broader and more
flexible range of powertrains.

Scania engines

All Scania engines are modularised and based on a unique cylinder design that
produces excellent performance and fuel economy. Having the same
combustion chamber design in all engine configurations makes it easier to strike
the right balance between performance, emissions and fuel economy.

Scania's 9-, 11- and 12-litre inline engines as well as the powerful 16-litre V8-
engines are all based on this cylinder design concept. The engine architecture is
similar in all variants, making maintenance and repairs straightforward for any
Scania technician. .

All engines feature cast iron cylinder blocks, wet, replaceable cylinder
liners and individual 4-valve cylinder heads – a layout that makes maintenance
and repairs considerably easier. A camshaft located high in the block actuates
all valves and injectors via roller tappets and short pushrods.

Parts and components are thus shared between the engines, so are work
methods in the workshop. This simplifies all types of service operations,
including diagnostics, maintenance, repairs, parts supply and service training

Engine performance

All Scania engines are optimised to give high torque and maximum economy at
low engine revs. The benefits of these characteristics are class-leading fuel
economy and on-road performance, while contributing to a relaxed driving style
and driver appeal.

The low-speed torque characteristic also allows long gearing that contributes to
relaxed cruising, less wear-and-tear and low in-cab noise levels.

Over the years, consistent engine development has resulted in significantly
improved engine efficiency and reduced fuel consumption - despite ever-stricter
emission standards.
As a result all Scania's new Euro 3 engines are more efficient than their

Besides diesel oil, Scania authorises the use of a mix of diesel and up to 5%
biodiesel complying with EN 590 in its engines.

Intelligent auxiliary equipment

The new truck range with the P-, G- and R-series features a brand new
electrical system based on CAN-bus technology. The system has been in
production for four years on Scania trucks produced in Europe and has proved
exceptionally reliable. It also allows much easier diagnostics and integration of
bodywork functions.

The engine management system interacts smoothly with other control systems
on the vehicle via this CAN-bus. This provides full control of all engine
auxiliaries, many of them incorporating innovative solutions that help save fuel.

For example, electronic management of the air compressor for brakes makes
the compressor charge the system when the engine is not under load. This
means that the air tanks are filled whenever the vehicle is braking or coasting
downhill, saving energy and fuel.

Intelligent control of the air-conditioning compressor adapts the cooling output in
relation to the desired cab temperature without intermediate warming of the air.

An electronically-controlled cooling fan is optional, instead of hydraulic control.
This option reduces friction, speeds up engagement and provides a more
precise coolant temperature regulation when needed.

The mounting points and auxiliary equipment are located in the same position
irrespective of engine version. The connection plane between engine and
gearbox is in the same orientation for all Scania engines.

An engine-driven power take-off can be specified for all Scania engines (230 to
580 hp). Driven by the timing gears at the rear end of the engine and mounted
at two o’clock, this PTO is sufficiently powerful and ideally located to drive the
hydraulic pump for a mixer, for example.

Scania 9-litre inline 5-cylinder engine

Based on the architecture and cylinders of Scania’s 11- and 12-litre inline 6-
cylinder engines, the 9-litre inline 5-cylinder is designed for durability in all
applications. Similar to Scania's other engines, the 9-litre develops high torque
within a broad rev band, pulling well from as low as 1,000 r/min.

The torque ratings for the 230, 270 and 310 hp versions are exceptionally high
for this class at 1,050, 1,250 and 1,550 Nm, respectively. The exhaust brake
develops 180 kW at 2,400 r/min and the fuel injection system has Scania PDE
electronic injectors.

Scania 11- and 12-litre inline 6-cylinder engines

The 11-litre 340 hp engine shares most parts and components with its 12-litre
cousins. The 340 hp output is combined with a torque of 1,600 Nm between
1,100 and 1,300 r/min (suitable for certain heavy-duty operations). The engine
brake develops 230 kW at 2,400 r/min and fuel injection is Scania PDE.

The 12-litre engines account for more than half of Scania’s sales. The three
versions develop 380 hp, 420 hp and 470 hp with torque figures of 1,900 Nm,
2,000 Nm and 2,200 Nm, respectively. The exhaust brake develops 247 kW at
2,400 r/min. The fuel injection system on the 380 and 420 hp versions is Scania

The 470 hp engine incorporates two unique Scania solutions that give it
exceptional performance in its class. Turbo compounding boosts low-speed
torque and fuel economy by recycling surplus energy from the exhaust gases. A
second turbine in the exhaust, downstream of the normal turbocharger, feeds
torque back to the crankshaft via a viscous coupling. This engine also features
the Scania HPI high-pressure injection system that further promotes low-speed
torque and reduces the formation of particulate matter in the exhaust gases.

Scania 16-litre V8 engines

The first Scania V8 truck engine launched in 1969 has become a classic with
legendary reliability and performance. The current 16-litre engine builds on this
tradition. It is based on the same modular engine platform as the 9/11/12-litre
engines, sharing many of their components. The cylinders are identical to those
on the 12-litre engine. The combination of high performance and outstanding
economy and reliability is virtually unique in the truck market today.

The cylinders banks are placed at an angle of 90º, making this V8 engine
perfectly balanced. The injection system is Scania PDE.

The 500 hp version develops 2,400 Nm, between 1,100 and 1,300 r/min. The
580 hp version develops a torque output of 2,700 Nm at the same revs. The
engine brake turns out a full 304 kW at 2,400 r/min.

Euro 3, 4 or 5

Besides Euro 3, Scania Euro 4 and Euro 5 engines are available on special


The gearboxes available for the new truck range are proven units from the 4-
Series. The gearbox range includes the 8-, 8+1-, 12- and 12+2-speed versions,
as well as an overdrive options. Other options include the Scania Retarder and
Scania Opticruise – a popular selection.

                  Option: Scania Retarder (GR900R)
GRS890            12-speed range-splitter gearbox
                  Options: Scania Retarder (GRS890R), Scania Opticruise
GRS900/920        12-speed range-splitter gearbox with two 2 crawlers
                  Options: Scania Retarder (GRS900/920R), Scania Opticruise
GRSO900           12-speed range-splitter overdrive gearbox with two 2 crawlers
                  Options: Scania Retarder (GRSO900R), Scania Opticruise.

The GRSO900(R) with overdrive is intended for the most severe applications in
combination with hub reduction drive axles. The overdrive can also be used to
achieve comfortable and economical on-road cruising revs, even on a
construction vehicle, for example.

All-wheel-drive vehicles (4x4, 6x6) have a transfer box for the front-wheel-drive
with direct-drive (1:1) and an extra low-speed ratio. They are available either in
combination with an 8+1-speed GR900(R) or 12-speed GRS890(R) gearbox.

Scania Retarder

Most gearboxes are available with the Scania Retarder auxiliary braking system.
Integrated at the rear of the gearbox, the Scania Retarder acts hydraulically and
interacts electronically with other control systems on the vehicle.

The Scania Retarder is controlled in five steps via the right-hand lever on the
steering column. When set to automatic (button on the lever), the downhill
speed is maintained automatically if the driver touches the brake pedal at the
desired speed.

The Scania Retarder output is adapted to the cooling capacity available in the
engine’s cooling system and cooling is optimised via the new electronic fan. The
exhaust brake and retarder work together to maximise braking output.

Scania Opticruise

Scania Opticruise is an automated gear changing system that copes with most
situations without driver intervention. The latest improvements give faster gear
changing and improved interaction with the Scania Retarder and the exhaust

The clutch pedal is only used to start and stop and when the driver needs to
stay in full command. According to Scania surveys, drivers appreciate having
the clutch pedal since it provides total control in precise low-speed manoeuvres
as well as on slippery roads and in other dangerous situations.
The system detects the load of the truck and adapts the gear changing strategy
accordingly. The starting gear can be pre-programmed and the system will
change down automatically to this gear.

Clutch protection

An optional electronic monitoring system prevents the clutch from being abused
when starting from a standstill. Engine revs are limited to 900 r/min when pulling
away. This engine speed is normally sufficient for a normal start with minimum
clutch slip. With a light on a flat road, all the driver needs to do is to release the
clutch slowly with the engine idling, and the truck will move off easily.

If the driver does not notice that the clutch is being overloaded, a yellow warning
message will be displayed in the instrument cluster.

Scania driven axles

Scania vehicles with one driven axle are available with single reduction as well
as hub reduction. Scania's driven front axle is a hub reduction version with ratios
that match different rear-axle combinations.

Single-drive axles
4x2, 6x2, 8x2: The single-reduction R660 is recommended for operations at a
