TPI Composites, Inc. has partnered with Navistar, Inc. on an all composite cab, trailer box, and aero package for the International® SuperTruck II. The project which was co-funded by the U.S. Department of Energy and Navistar, brought together leaders in their respective industries to design and manufacture a Class 8 vehicle that demonstrates the future of hybridization and aerodynamics. The lightweight, aerodynamically designed composite cab and trailer components manufactured by TPI contributed to the International SuperTruck II achieving 16 mpg in real-world operation and a 170% improvement in freight efficiency over the 2009 International SuperTruck I. With faster development times, lower investment costs, and reductions in mass when compared to traditional metallics, composites are becoming more prevalent structural solutions as the commercial truck market migrates to zero emission vehicles.

The replacement of steel and aluminum with composites can provide significant weight reduction and design flexibility, the International SuperTruck II demonstrates this by shedding 500 lbs. with the aero package when compared to the International SuperTruck I.
