We dive deep into the heritage of iconic race cars to capture their essence and reimagine them through modern composite engineering. By scanning and digitally reconstructing one of the few surviving Gruppe-5 BMW E9 body elements, we created precise CAD models that preserved every curve and proportion of the original. From there, lightweight carbon fiber panels were developed to reduce weight, improve stiffness, and enhance on-track performance, all while maintaining the timeless silhouette that defines the E9 legend. This process reflects our ability to honor motorsport history while delivering innovation that makes it race-ready for the modern era.
Project Overview
The Hell BMW E9 project was a unique motorsport build led by Gabura Motorsport, where performance, aesthetics, and engineering excellence came together. Our team contributed by designing and manufacturing lightweight carbon fiber body panels for this iconic race car. To ensure authenticity, one of the few surviving original Gruppe-5 BMW E9 body parts was 3D-scanned and reverse engineered, serving as the foundation for the new composite components. The aim was to reduce weight significantly, increase structural rigidity, and provide the vehicle with a modern competitive edge while preserving its legendary silhouette.
Process Planning
The project began with digitizing the historic body elements and creating precise CAD models that captured the essence of the Gruppe-5 design. Based on these models, manufacturing strategies were developed to replace the original steel panels with CFRP counterparts, maintaining exact fitment and durability. Careful planning ensured that the composites would withstand the demanding motorsport environment, where high dynamic loads, vibrations, and thermal stresses are ever present.
Manufacturing
The body panels were produced using CFRP layups, combining lightweight construction with high stiffness. Precision molds and controlled curing processes guaranteed repeatability and dimensional accuracy. The result was a set of carbon fiber components that not only reduced the vehicle’s overall weight but also elevated its handling and performance on the track. This project demonstrates the fusion of motorsport heritage with cutting-edge composite engineering.
