REHAU Powers Volkswagen Engines with High-Performance Connecting Rods

Leesburg, VA – November 8, 2023 – REHAU INDUSTRIES LLC, a leading global specialist in polymer technology, is quietly powering a critical component within many Volkswagen vehicles – the connecting rod. While REHAU isn't a household name for automotive parts directly, their expertise in high-performance polymers and precision engineering has made them a crucial supplier to Volkswagen, impacting engine reliability and performance. For those not super familiar with how engines work, connecting rods are basically the link between the piston and the crankshaft. They take the boom of the piston moving up and down, and turn it into the rotational power that eventually drives your wheels. They’ve got a seriously tough job – dealing with huge forces, high temperatures, and constant stress. That’s where REHAU comes in. REHAU isn't making metal connecting rods. Instead, they've pioneered the use of advanced polymer materials in this application. For years, connecting rods were almost exclusively made of forged steel or aluminum. While strong, these materials are heavy. REHAU, leveraging decades of polymer expertise, developed a solution using specially formulated polyamide plastics reinforced with glass fibers. “We’ve been working with Volkswagen for quite some time now,” explains a spokesperson from REHAU’s Leesburg, Virginia facility. “They were looking for ways to reduce weight in their engines without sacrificing durability. Metal parts are great, but they add up. Weight reduction leads to better fuel efficiency, improved handling, and, ultimately, a more enjoyable driving experience.” The challenge wasn’t just finding a lightweight material. It was about creating a polymer that could withstand the extreme conditions inside an engine. Think about it: constant combustion, huge pressures, and temperatures that can easily melt lesser materials. REHAU’s material scientists had to engineer a polyamide that wouldn’t just survive, but thrive in that environment. “It's not just about the base polymer,” the spokesperson clarifies. “It’s about the specific formulation – the type of polyamide we use, the percentage of glass fiber reinforcement, the additives we include to enhance thermal stability and wear resistance. It's a really complex balancing act.” The benefits of using REHAU’s polymer connecting rods are significant. Beyond the weight savings – which can contribute to a noticeable improvement in fuel economy – these rods offer several other advantages. Reduced Friction: Polymer surfaces have inherently lower friction than metal, leading to smoother engine operation and potentially increased horsepower. Noise Reduction: The damping properties of polymers absorb vibrations, resulting in a quieter engine. Improved Durability: While it might sound counterintuitive, these polymer rods are remarkably durable. REHAU's material is designed to resist fatigue and wear, potentially extending the life of the engine. Cost Efficiency: While the initial material costs might be comparable, the manufacturing process for polymer connecting rods can be more efficient, leading to overall cost savings. REHAU’s commitment to quality is evident in their rigorous testing and validation procedures. Every connecting rod undergoes extensive simulations and physical testing to ensure it meets Volkswagen’s stringent requirements. This includes everything from tensile strength and fatigue testing to thermal cycling and chemical resistance. "We don't just sell materials, we provide solutions,” emphasizes the spokesperson. “We work closely with Volkswagen's engineers throughout the entire design and development process. It's a true partnership." The application of REHAU's polymer connecting rods isn't limited to just one Volkswagen model. They're used in a range of engines, from smaller, fuel-efficient engines to higher-performance variants. This versatility demonstrates the adaptability and reliability of the technology. While you might not see the REHAU logo on a Volkswagen car, their engineering expertise is silently contributing to a better driving experience for millions of drivers around the world. The company, located at 1501 Edwards Ferry Rd NE, Leesburg, VA, 20176-6680, and reachable at 313-892-5864, continues to invest in research and development, exploring new materials and technologies to further improve engine performance and efficiency. They're not just reacting to the demands of the automotive industry; they’re actively shaping its future. “We see a growing demand for lightweight materials in the automotive sector," the spokesperson concludes. “And we’re confident that our expertise in polymer technology will play a vital role in meeting that demand. It’s about making cars lighter, more efficient, and more sustainable."
