Volkswagen Group recently celebrated the 20th anniversary of its largest research facility outside Germany by unveiling a retrofitted 1962 VW Microbus. This unique vehicle is not just a nostalgic tribute, but also a showcase of cutting-edge technologies that could shape the future of the automotive industry. Collaborating with Autodesk, the Innovation and Engineering Center California (IECC) reimagined key components of the electric-powered vehicle, focusing on reducing weight while maintaining structural integrity.
"Combining a classic design with modern innovations from partners like Autodesk is an exciting way to explore what’s possible," said Nikolai Reimer, executive director of IECC. "This project represents our vision for the future and gives us a chance to create something truly special."
One of the biggest challenges in electric vehicle development is minimizing weight. Lighter vehicles require less energy to move, leading to improved efficiency and longer range—two critical factors for consumers. To address this, Volkswagen used generative design, a powerful tool that allows engineers to create optimized structures that are both lighter and stronger than traditional designs.
The wheels of the Microbus were one of the first components redesigned using this approach. The result was a 18% reduction in weight, without compromising performance. The entire development process, which typically takes over a year, was completed in just a few months.
"Generative design opens up new possibilities we couldn’t have imagined before," said Andrew Morandi, senior product designer at Volkswagen. "Seeing the final rims arrive felt like Christmas morning. It was incredible to see how much material could be removed while still maintaining strength and function."
In addition to the wheels, the steering wheel, rear seat support structure, and side mirror mounts were also redesigned using generative techniques. These changes not only reduced weight but also created more visually striking components that highlight the potential of this technology.
Erik Glaser, principal product designer, explained why the steering wheel was chosen as a focus: "It's the driver's primary touchpoint, so it's important to make it both functional and beautiful. Generative design allows us to create intricate, strong parts that people can actually feel and appreciate."
Beyond aesthetics, generative design offers practical benefits such as faster workflows and better-informed decisions. It’s already being used in other industries, including aerospace. For example, NASA recently unveiled a generatively designed lander prototype capable of traveling over 350 million miles.
"We’re just scratching the surface of what generative design can do," said Reimer. "In the next decade or two, we could see entire vehicle frames designed this way. This could completely transform how cars are made and how we work."
As companies like General Motors and NASA continue to explore the potential of generative design, it’s clear that this technology is here to stay. With the right combination of human creativity and AI, the future of product design looks lighter, smarter, and more sustainable.
