Aero Tec Laboratories Introduces Kevlar® EXO™ Fuel Bladders for WRC Cars

Introduction

In a significant leap for motorsport safety and efficiency, Aero Tec Laboratories (ATL) has partnered with DuPont to integrate the revolutionary Kevlar® EXO™ material into fuel bladders used in World Rally Championship (WRC) cars. This new collaboration was formally announced ahead of the WRC Delfi Rally Estonia, marking a milestone in the ongoing effort to enhance safety and performance in racing.

The Innovation

The latest generation of fuel bladders, made with DuPont's Kevlar® EXO™, are designed to be crash-resistant, significantly improving the safety features of rally cars. These innovative bladders not only offer a formidable level of protection but also help in reducing the overall weight by approximately 20%. This weight reduction is critical in competitive motorsport, where every ounce counts towards better performance and speed.

DuPont's Kevlar® EXO™ has been heralded as the most significant advancement in aramid fiber technology in over 50 years. Initially launched for life protection applications in April 2023, Kevlar® EXO™ combines flexibility with a lightweight strength that has opened new possibilities in various applications, including protecting satellites from orbital debris and enhancing the comfort of bullet-resistant vests.

Performance Meets Safety

DuPont's Segment Leader, Jill Clements, expressed excitement about expanding their collaboration into the WRC after the prior success witnessed in Formula One. "The utilization of Kevlar® EXO™ in fuel bladders enables teams to achieve enhanced performance while prioritizing safety, fuel compatibility, and overall efficiency," Clements noted. This dual focus on safety and performance aligns with the increasing demands and challenges posed by the introduction of new sustainable fuels in motorsport, especially in the extreme conditions faced by WRC competitors.

ATL's CEO, Giles Dawson, elaborated on the extensive testing that went into developing these fuel bladders, emphasizing their commitment to ensuring safety and efficiency in the face of changing technologies in the motorsport landscape. The innovation allows teams to gain a competitive edge while ensuring the reliability and protection that drivers expect from modern racing equipment.

Future Endeavors

The partnership between DuPont and ATL doesn't stop at the WRC; both companies are eager to expand their innovations further into other motorsport series, including NASCAR and IndyCar. The racing industry continues to evolve rapidly, and both companies are prepared to adapt and provide cutting-edge solutions that prioritize speed, safety, and sustainability.

Through this collaboration, DuPont and ATL set an exciting precedent for how materials science can redefine norms within the automotive racing world, ensuring that advancements in safety technology resonate throughout the fabric of competitive motorsport.

Conclusion

The introduction of Kevlar® EXO™ fuel bladders in the World Rally Championship represents a pivotal development in race car safety and performance. As DuPont and ATL continue their journey together, their innovative strides will undoubtedly influence not only current racing practices but also shape the future of motorsport safety. Enthusiasts, teams, and drivers alike can look forward to a new era in racing, characterized by enhanced safety measures and improved performance dynamics, thanks to this game-changing technology.
