In a groundbreaking collaboration, McLaren Automotive has partnered with California-based Divergent Technologies to deliver advanced suspension hardware for its newly unveiled supercar, the McLaren W1. Known for its expertise in next-generation additive manufacturing, Divergent brings cutting-edge 3D printing technology to McLaren’s latest creation, pushing the boundaries of performance engineering. Launched earlier this month, the McLaren W1 is the highly anticipated successor to the legendary F1 and P1 supercars, combining a V8 hybrid powertrain with an astonishing 1,258 horsepower. Its Formula 1-inspired front suspension is directly mounted into the Aerocell carbon fiber monocoque, ensuring both lightness and strength. With features like hydraulic steering and braking, and an aerodynamic design that delivers up to 2,205 lbs of downforce, the W1 offers a driving experience that blurs the line between road car and race car. Precision in Every ComponentThrough advanced 3D printing techniques, Divergent has created key components such as the front upper wishbone, aero form lower wishbone, and front upright. These parts, essential for maintaining both structural integrity and lightweight efficiency, not only enhance the car’s performance but also contribute to its distinctive appearance. The exposed front wishbones keep the W1’s suspension stable at high speeds. However, the aero form lower wishbone serves a dual purpose, directing airflow around the car to improve its aerodynamic efficiency while also supporting the suspension’s structural demands. Divergent’s advanced additive manufacturing allows for rapid prototyping, enabling McLaren’s engineers to iterate and refine each component quickly. This flexibility has been crucial in optimizing the balance of size, weight, and shape. Unlike conventional methods, where complex shapes can drive up costs and development time, Divergent’s 3D printing technology eliminates these limitations. This freedom allows McLaren to swiftly adjust designs in response to wind tunnel testing, where even minor aerodynamic issues can be addressed with near-immediate refinements. Divergent’s expertise, showcased in projects like the Bugatti Tourbillon and Porsche 911 GT3 RS, brings unparalleled experience to the McLaren W1. The result is a suspension system engineered for precision, providing both the stiffness and feedback necessary for high-speed driving, while also enhancing driver engagement. 3D Printing is Gaining Ground in Supercar DesignThe use of 3D-printed suspension components, once limited to a few groundbreaking hypercars, is rapidly gaining traction among high-end automakers. The Ferrari F80 is one of the latest models to feature these advanced parts, building on the innovations pioneered in the McLaren W1. According to Kevin Czinger, Founder and CEO of Divergent Technologies, several other automakers are already exploring the potential of this technology, although they may not be ready to publicly acknowledge their interest just yet. At this stage, 3D-printed suspension remains the domain of hypercars like the McLaren W1 and Ferrari F80, where the higher costs can be justified by the performance gains. However, the potential for this technology extends far beyond the ultra-exclusive hypercar market. Czinger believes that, as production methods improve and costs decrease, 3D-printed components will become more widespread in the supercar segment. Just as hybrid systems trickled down from models like the McLaren P1 and Ferrari LaFerrari to more accessible models like the Artura and 296 GTB, 3D-printed suspension is set to follow a similar path. With 3D-printed suspension, the benefits are clear: lighter, more complex parts can be created without the constraints of traditional manufacturing. As wind tunnel testing and real-world performance data accumulate, automakers will be able to refine these components even further, ensuring maximum performance while maintaining strict cost-efficiency. Kevin Czinger highlights the unique position of 3D printing in supercar development: "We are proud to partner with McLaren on their newest engineering marvel, the W1. The suspension hardware designed and manufactured by Divergent has enabled the McLaren team to push the boundaries of what is possible in this digital manufacturing age of supercar production." McLaren CEO Michael Leiters echoed this sentiment, saying, "This cutting-edge technology has enabled us to develop more complex suspension structures in the McLaren W1, enhancing the driving experience and supporting our mission to push the boundaries of performance."
