Your System Partner for Advanced Roof and Kinematic Solutions
CTS develops and manufactures vehicle roof systems that meet high standards for weight, design, appearance, and quality. In addition, sound-insulating solutions are used to ensure optimal interior acoustics.
The targeted use of lightweight materials such as aluminum and die-cast magnesium components results in weight-optimized roof systems. The respective folding designs are individually tailored to the vehicle’s installation space and integration requirements.
CTS’s product portfolio includes soft tops, retractable hard tops, folding roofs, and modular roof systems. Our development and production processes are consistently geared toward meeting our customers’ needs, resulting in technically sophisticated, innovative roof solutions.

CTS stands for quality beyond specifications and tolerances. Quality that customers can feel with every movement.
At CTS, quality is not a separate step in the process. It is an integral part of the entire development and manufacturing of our products. Especially with complex roof systems, it is not enough for a system to simply function. What matters most is that every movement is precise, quiet, and consistently reliable—even after many years of use.
That is why, for us, quality begins right at the development stage. Robust designs, virtual validation, and a deep understanding of kinematics and system integration form the foundation. During industrialization and production, clearly defined processes, coordinated testing concepts, and close collaboration between development and manufacturing ensure that this quality is also achieved in series production.
Our approach to quality is strongly shaped by our roots in the premium segment. High process stability, consistent error prevention, and reliability are at the heart of everything we do. CTS stands for roof systems that not only meet technical requirements but also impress with their quality in everyday use. In every journey. In every movement.
