In a groundbreaking collaboration, MycoWorks and General Motors have introduced a new era of sustainable automotive design with the Cadillac SOLLEI. The luxury electric vehicle features an eco-friendly leather crafted from mycelium, a mushroom-based bio-material, in specific parts of its interior. This partnership marks a significant leap toward eco-conscious materials in the automotive industry, with the Cadillac SOLLEI becoming the first vehicle to showcase mycelium-made material in components like charging mats and door map pockets.
Mycelium: A sustainable alternative
Mycelium, the root structure of mushrooms, is gaining recognition for its remarkable sustainability and versatility. MycoWorks, a biotechnology company specializing in mycelium-based materials, has been at the forefront of this revolution. Since its founding in 2013, MycoWorks has been pushing the boundaries of material science with their Fine Mycelium™ technology, which allows them to engineer mycelium into leather-like materials.
Fine Mycelium™ was developed to create mycelium sheets tailored to specific needs, such as texture, strength, and durability. “For the first time, brands and designers have full control over a natural material, adding new benefits like supply-chain traceability and material consistency,” said Bill Morris, Vice President of Product at MycoWorks, in a recent interview with designboom.
The Fine Mycelium™ platform creates materials that rival traditional leather in terms of strength and texture but with a much smaller environmental footprint. Mycelium is “infinitely renewable,” as MycoWorks describes it, making it a highly sustainable alternative to leather. In the case of Cadillac’s SOLLEI, MycoWorks engineered mycelium leather for the car’s charging mats and door map pockets, providing an eco-friendly yet luxurious touch.
The Cadillac SOLLEI: A design inspired by sustainability
The Cadillac SOLLEI, revealed at Cadillac House in Michigan, represents an interesting step forward for General Motors and its luxury brand, with the electric car combining cutting-edge technology with sustainable materials. According to Erin Crossley, Cadillac’s design director, the SOLLEI “cultivates the vision for limitless expression and artful integration between travel and leisure.”

The use of mycelium leather in the SOLLEI is not just a design choice; it aligns with the broader trend of automotive companies seeking more sustainable materials. Laetitia Lopez, Cadillac’s Global Color, Materials, and Finishes Design Manager, emphasized that the choice to incorporate mycelium stemmed from Cadillac’s desire to explore innovative, low-impact materials without compromising luxury or performance.
Fine mycelium’s journey to the automotive industry
This partnership between MycoWorks and GM began in 2022 when they first explored the use of Fine Mycelium™ in automotive design. The SOLLEI concept car marks the first time that MycoWorks’ material has been applied in an automobile, but it’s clear that this is only the beginning, as MycoWorks continues to innovate with their technology. In the interview, MycoWorks’ creative director, Xevi Gallego, explained the design process behind the mycelium material used in the SOLLEI. “Mycelium is a structural marvel: malleable and adaptable,” he said. “Together, we developed the iridescent material so that it seamlessly blended with the beauty and eco-conscious design, and narrative of the overall car.”
The future of mycelium in automotive design
The implications of this partnership extend far beyond the Cadillac SOLLEI. MycoWorks envisions a future where Fine Mycelium™ could be used in a variety of applications within the automotive industry, from seat covers to dashboards. In fact, as Gallego pointed out, the potential of this material could reduce waste and speed up supply chains by growing mycelium sheets to the exact specifications of car parts like steering wheels and dashboards.
Beyond automotive, mycelium materials have already made waves in other industries. From fashion to furniture, the environmental benefits of mycelium are pushing industries to adopt it as a sustainable alternative to traditional materials. In the fashion industry, for example, mycelium-based fabrics are being explored as a solution to the industry’s massive carbon footprint.
A step towards a greener future
The Cadillac SOLLEI’s use of mycelium leather is an exciting development in sustainable design. As consumers demand more eco-friendly products, collaborations like this between MycoWorks and General Motors show that luxury and sustainability can coexist. MycoWorks’ Fine Mycelium™ is not just an alternative to leather—it’s a look into a future where bio-based materials could replace plastic, leather, and other environmentally damaging materials across industries. In a world where sustainability is increasingly vital, the Cadillac SOLLEI is a bold step forward, demonstrating how the power of innovation and material science can change how we think about manufacturing across all industries.
