Body in White
Function fulfilment and cost efficiency are the challenge, lightweight construction and hybrid technologies are our tools.
We take responsibility for the development of complete bodies and act as a system integrator at all relevant interfaces. Our goal: production-optimised development with optimum product features at minimum cost and weight.
Architecture – definition
Modular / monocoque / hybrid design and spaceframe
NVH acoustic measures
Seam sealing

Doors, Covers
We specialise in design methodology, and have have a profound understanding of materials, component features and function integration.
We rise to the challenge of developing complex module functions and using sustainable material concepts.
What we ensure with our functional design services:
- Innovative and flexible development tailored to your requirements
- Challenging module development connected by kinematic systems
- Function validation by means of simulation and testing

Perceived value and quality play a significant role here. Finding the balance between look, feel, usability, function and cost is what guides us in interior development.
Involved in the early project phases of concept selection and material definition, we work to achieve an ideal solution to the conflict between quality and cost.

One of our core skills is the complete vehicle package for battery and fuel cell vehicles including completion of the prototypes.
With our broad portfolio, we offer you a service specially tailored to the commercial vehicle industry, which is then reflected as added value in the products.
Highlights from the Technical Department
Our Lightweight Know-How for Your Heavyweight
Especially in commercial vehicle development, our expertise in lightweight construction comes into its own. Here, every kilo counts!
In addition to weight, different construction methods and application profiles of commercial vehicles are challenging. How is it possible to ensure that production is flexible, cost-optimised and weight-saving at the same time?
- Modular front end concept shows technological foresight
As early as 2016, we demonstrated our technological vision using the example of a modular front-end concept. Our bridge technology, consisting of large cast nodes and roll-profiled longitudinal and transverse beams, makes it possible. Another highlight is our weight and cost-optimised multi-material system for commercial vehicle cabs, with its single-step joining and painting process.
- Potential of 3D printing
"3D printing" can possibly provide a solution to these difficult questions: Particularly topologically designed, complex geometries could be produced in series from data records without restrictions, without tools and in one production step in a highly variant-intensive manner. This would pave the way to be technically able to manufacture customised trucks economically for all operating requirements. "Complexity for free" and "Variants on demand" are attractive advantages of generative processing.
With our generatively processed demonstrator of a truck cab and the respective chassis, we have shown some years ago how this trend could be implemented in the future. Not only does the enclosed cage structure make better use of the available space toward the road, its topological design also means that it leads the way in terms of weight-saving. Along with additive manufacturing, autonomous driving is another subject that is far from being restricted to passenger car development only. EDAG is expecting the "self-driving commercial vehicle" to become a megatrend in the commercial vehicle industry, and is developing an extra security-sensitive software capable of enabling several commercial vehicles to carry out a wide variety of manoeuvres in formation.
Our EDAG Light Cab is proof of the fact that, apart from our visionary concepts, we also have affordable lightweight design solutions up our sleeve. Due to variable profiles, the cab is scalable, and can be used for vehicles weighing anything from 16 to 40 tonnes. With the Light Cab, we have managed to develop a cab which, at no extra cost and while retaining structural properties, is up to 24% lighter than today's conventional bodies.
We are also offering a further thought-provoking impulse, this time along the lines of urban goods traffic, in cooperation with the Technical University of Kaiserslautern. The 4-in-1 truck is a ground-breaking concept designed to provide a cost and time-saving means to avoid inner city access restrictions.
Special vehicles call for special know-how. Regardless of whether they are for public transport, construction, heavy goods transfer or emergency vehicles. With their aim to make commercial vehicle development of tomorrow even better, more lightweight and flexible, our EDAG experts are the right people for you to contact.
