Scania Super

Ready to meet the toughest emissions targets of tomorrow and serving as the heart of a powertrain that sets a new industry-leading fuel economy standard, the Scania Super engine becomes the most advanced combustion engine we have ever built.

Behind the Super’s unrivalled performance level lies significant improvements to the engine’s combustion and aspiration performance, lubrication and cooling, and turbocharging efficiency. It also features a range of industry-leading engine technologies, such as the Scania Twin SCR system, and a new, powerful engine management system to ensure the engine’s superior total operating economy under all conditions.

The engine doesn’t just excel in the efficiency stakes, it is also supremely robust. The Super’s outstanding technical robustness is engineered to give you more uptime, fewer maintenance stops, and an increased operational life length by as much as 30%. All of this combines to give you unrivalled total operating economy and keep your business rolling further than ever beyond the transport challenges of tomorrow.

• Available in 420hp, 460hp, 500hp and 560hp
• Full torque available from 900 RPM for improved driveability
• Increased uptime due to longer maintenance intervals
• Better productivity and increased payload (with optional CRB)
• The possibility to add Active Cruise Control (AiCC) without retarder (with optional CRB)
• 2 new optional engine-driven PTOs offering increased torque up to 1000Nm and power output up to 238kW
• Integrated Management of the complete powertrain performance   

The industry-leading Scania Twin SCR system is the centrepiece of the Super’s unmatched efficiency. Introducing dual dosing of AdBlue in the powertrain’s aftertreatment process, the Scania Twin SCR system makes it possible to redefine the limits of combustion performance, while still meeting future expected legal requirements with even higher demands on nitrogen oxide emissions.

Premium power and stamina  

With a power range up to 560hp and torque up to 2800Nm, the Super delivers more power than ever before on a Scania 6-cylinder inline engine. It also features extreme stamina, producing effortless propulsion and peak torque at lower RPM.

Integrated auxiliary braking  

The Super’s engine-integrated compression release brake (CRB) system introduces powerful auxiliary braking capacity up to 350kW – delivering a smoother and safer drive. Enabled through the Super’s cylinder head design, with dual overhead camshafts and an optimised valve train, the optional, low-weight CRB can even replace or complement the Scania R4700D retarder depending on your operation.

How do you improve on an engine platform that has won the European Green truck award five years in a row? How do you develop a powertrain that will strengthen Scania’s industry-leading position within sustainable transport for the rest of this decade? 

The developers at Scania Technical Centre who were given these assignments say the answers are: determination, innovation and customer focus.

“Starting from scratch meant we could concentrate all our design work with the customers’ needs in focus, without restraints. That’s why we can present a product that the transport industry really needs here and now to take the necessary steps towards a sustainable future,” says Assistant Chief Engineer Linda Pukk Berggren. 

“Fuel consumption is significantly reduced for a very broad part of the engine speed and load area. This means that many different applications, such as long-haul, construction and forestry vehicles, will all benefit from the improvements and emit less CO2,” says Magnus Nilsson, Technical Manager within Aftertreatment. 

Thanks to this outstanding energy efficiency and other major updates in Scania’s powertrain – fuel savings of eight percent or more can be reached for long-haulage operations. And that’s in comparison with Scania’s already industry-leading performance levels. Efficient just became super-efficient.

So, what’s ‘under the hood’ of the Super 13-litre engine? Quite a lot, in fact. 

Feature including dual over-head camshafts, optimised injectors, improved combustion, an optimised high-pressure fuel pump, improved cooling and lubrication, increased turbocharger efficiency, and a state-of-the-art engine management system.

Not only that; Scania’s successful dual dosing Selective Catalytic Reduction system, which has been proven to offer excellent fuel saving capacity and increased productivity and uptime, has been remade from the ground up. The system has earned a name of its own: Scania Twin SCR.

Scania’s standard and heavy-duty Opticruise range is key to realising the fuel-saving potential of the Super engine platform. Light, compact, smooth and quick, it is the perfect match for the 13-litre engines.

When Scania’s engine developers were pushing the limits to create the cleanest and leanest combustion engine platform the world has ever seen, they had to give it the best possible conditions to fulfil its full potential. That’s why, even at an early stage in the development project, there were tight connections between Scania’s engine developers and their transmission and gearbox colleagues.

“This approach made it possible for us to design the powertrain totally from scratch, with a holistic perspective,” says Peer Norberg, Senior Engineer in Scania’s transmission development team.

Delivering on the powertrain’s fully integrated low-rev design philosophy Scania introduces the faster-gearing R756 single reduction rear axle – offering a wider range of gear ratios from 1.95 to 4.11, and purpose-designed to enable the exceptional fuel efficiency of the Scania Super powertrain.

Together with reduced component weight, improved technical robustness, and lower levels of internal friction, the Scania R756 single reduction rear axle is versatile enough to master a whole range of haulage applications. 

• The Scania R756 single reduction rear drive axle replaces the Scania R665, Scania R753 and most Scania R780 axle applications, serving a wide range of vehicle operations up to a gross train weight of 53 tonnes, from light long haulage to tippers and refuse collections

• The improved robustness of the Scania R756 is designed to deliver an increased operational service lifetime, as well as extended service intervals

• R756 offers a reduced component weight of up to 27 kilograms compared to the Scania R780 single reduction rear axle

• Permanent oil filter enables reduced maintenance cost and contributes to an extended oil change interval by as much as 50%, depending on your operation type

Lower energy losses. Improved efficiency. One percent fuel saving from the rear axle alone. Even more to gain thanks to the full integration with the gearbox, making it possible to utilise faster rear axle gears. Scania’s team of axle developers has done it again. 

Where would Scania’s low-rev and high-torque philosophy be without the cutting-edge components and software that make the complete truck greater than the sum of its parts?  Well, it wouldn’t be Super if each piece wasn’t super too. 

That’s why the developers and construction engineers at Scania Technical Centre in Södertälje, Sweden, have always had an eye on the most minute details: wherever there is greater efficiency to be obtained, wherever there are grams that could be cut to make it lighter, wherever there is friction to reduce, wherever there is a penny to save for the customers, it’s worth pursuing. 

“We’ve managed to present a killer component. This is a rear axle that fits the world’s best powertrain,” says Torvald Ilg, Chief Engineer within Axles and Propulsion Development at Scania and one of the developers that has been working on the rear axle programme.  

“It’s great to design a component that makes the driver a bit happier each time he or she fills up the tank,” he adds. 

The rear axle gear – an all-round single reduction axle – is the first to be released in an entirely  rear axle programme focused on improved efficiency. The axle gear will by itself reduce fuel consumption by as much as one percent due to reduced internal friction. And together with increased gear ratio spread of the G33 and G25 gearboxes, there is the potential for additional fuel savings.

So, how did Scania’s R&D team manage to improve the efficiency of the rear axle? The axle housing is lighter than the previous model. Special, low friction bearings are used throughout, which is especially important on the pinion gear. What’s more, the parts have tighter tolerances and are more smoothly machined in production, leading to minimal energy losses. 

Torvald Ilg also says his team has had close contact with the other Scania developer teams, who are focusing on the 13-litre Super engine platform, the gearbox, as well as the tanks and flexible chassis, respectively. 

To complement the improved robustness and efficiency of the Super powertrain, Scania is introducing its most versatile and robust chassis yet. Based on the Scania modular system and offering a more predictable chassis layout, MACH, Scania’s Modular Architecture Chassis, gives you more opportunities to specify and operate your Scania truck in a way that is truly tailor-made for its application and your business. Not only is this designed to give you an easier bodybuilding process, but it can significantly improve load distribution, payload potential and the operative range of your Scania truck.

Robust fuel tank range

Scania introduces a range of aluminium D-shaped fuel tanks, ranging from 165 litres to 910 litres and featuring a geometric design which is lighter and more robust than ever.

Harness more fuel than ever before

When specified with the Scania Super 13-litre engine, the fuel tank range comes with a fuel optimization unit fitted to the side wall, offering easy access to service points and the ability to increase the usable fuel volume in the tank. This reduces your tank’s dead weight, giving you a longer operative range and ensuring that you can harness more fuel from your tank than ever before.

Improved AdBlue ratio

Scania’s side-mounted SCR tanks are a crucial part of the Scania powertrain’s superior emissions control. The Scania Twin SCR system introduces higher AdBlue volume capacity, delivered through 123-litre and 150-litre SCR tanks, to continue ensuring a full 1:1 volume ratio between your Scania truck’s fuel and AdBlue capacity. 

• The chassis introduces a set of rules for frame hole patterns, with dedicated holes for mounting parts both inside and outside the frame. The result is a more modular and predictable chassis layout, increasing the theoretical number of chassis layouts exponentially

• The chassis layout enables more usable fuel and a 1:1 SCR/fuel ratio to be achieved, producing a greater operative range

• The chassis’ optimised fuel capacity and load distribution also results in an increased payload for our customers

• Improved chassis composition flexibility allows for better integration between truck and bodywork. This facilitates a much smoother and more cost-efficient bodybuilding process, as well as improving traction, payload and productivity. For example, the layout now makes it possible to mount chassis components (e.g. fuel tank) starting either from the front- or the rear axle. The improved weight distribution can significantly increase payload potential, while at the same time creating free space for additional chassis components

When it comes to developing the most energy-efficient truck the transport industry has ever seen, everything counts. Which is why Scania has put considerable resources into developing a new flexible chassis and tank programme, which plays an important part in realising the full potential of the new engine range, aftertreatment system, gearbox and rear axles.

“The tank programme enables us to maximise the uptake of fuel in the tank. Our philosophy during the development project was: “Why carry extra fuel as dead weight, when you can use it for load capacity instead?” says Aline Ferraz Larsson, a design engineer at Scania R&D.

The chassis and tank programme features D-shaped fuel tanks made from aluminium. The tanks are more robust yet also lighter, and their design increases fuel utilisation. Side-mounted SCR tanks are also included. All of this increases the vehicle’s uptime. 

At the same time, Scania’s developers have improved the flexibility of the frame and the chassis composition. 

“This gives the customer more choice for where to place the tanks on the frame, which is a great improvement for both them and truck body builders, since it creates opportunities for more efficient load distribution,” says Paula Pukk, Scania’s Head of SCR System Installation.

One of the keys enablers of Scania Super’s unmatched efficiency is the clever fuel optimisation unit. This unit is attached to the primary tank and works as a catch tank. 

“The way that the catch tank is set up with electrical pumps enables the user to have ‘fuel on demand’: we get exactly the amount of fuel the engine needs, and no more,” says Alex Elofsson Alenius, a development engineer who worked on the project.

The fuel optimisation unit brings a host of other improvements for customers, and for the overall performance of the powertrain. There are now longer service intervals for the two pressurised fuel filters. These service intervals have been aligned with the oil change intervals, which means fewer visits to the workshop and more time on the road.
