Easier customisation with Scania's modular system
A limited number of building blocks – many variations. Thanks to the modular system, Scania customers will receive exactly the right vehicle for their transport needs. The system also gives Scania’s customers global access to parts and to fast, reliable service.
To a growing extent, Scania uses shared components in trucks, buses and coaches, as well as industrial and marine engines. Some examples: all Scania engines have the same cylinder architecture and a Scania coach today has a large number of chassis and powertrain components in common with a truck chassis.
Furthermore, all of Scania’s truck cabs – regardless of size – have the same interface with the chassis. All engines and gearboxes have the same mounting points on the chassis, irrespective of size. The chassis in turn is built up by a large number of frame components that fit together in innumerable combinations.
Scania laid the groundwork for modularisation more than 50 years ago and has been refining the system ever since.
The concepts behind a modular product range existed at Scania as early as the 1930s. And when Sverker Sjöström − an engineer specialised in materials strength and testing and later Technical Director for many years − began working at Scania in 1947, the development department moved into overdrive.
The key concepts, then as well as today, are: standardised interfaces, few components and carefully defined steps for each line of components. This yields a specification system with immense variability, few components and as many shared parts as possible.
In 1980 when Scania unveiled the 2-series, or GPRT range, it was regarded as a major technical success. For the first time, Scania presented an entire commercial vehicle model range largely based on modules.
The modular philosophy not only means that vehicles can be tailored to the needs of individual customers. It has also been an important factor for product development at Scania. Each individual component, such as the engine, transmission, frame, cab and axles, can be further refined independently of other components. Improvements are introduced continuously as soon as they have been thoroughly tested, always giving customers access to the latest execution.

The modular system emerges
1930s: The “Royal” unitary engine unveiled − the first Scania engine to use standardised components.
1940s: In-house gearbox production. Collaboration with Leyland led to a new engine featuring direct-injection technology.
1950s: Scania’s engines modularised. Strength Testing Laboratory built up. Systematic analysis of design for different applications.
1960s: Scania bought a cab factory in Oskarshamn. Development of modularised cab range. In-house frame workshop.
1970s: Cabs and chassis modularised.
1980s: The 2-series (GPRT), Scania’s first fully modular product range, was launched. The 3-series introduced.
1990s: The Streamline cab was launched. The 4-series introduced.
2000s: Fully modularised 5-, 6- and 8-cylinder engine range. Global specification system.
