Daimler Truck North America (DTNA) completed a five year, $40.1 M SuperTruck 2 project to demonstrate technologies to achieve both vehicle and engine efficiency improvements. The vehicle objective was to develop and demonstrate a concept vehicle with at least 115% vehicle freight efficiency improvement over a weighted average of four cycles relative to a 2009 best-in-class baseline vehicle. The engine technology development goal was to achieve 55% brake thermal efficiency (BTE) as tested on a dynamometer at an equivalent of 65 MPH. Both project objectives were to develop technologies that are cost effective. SuperTruck 2 started in 2017 and built on the knowledge gained in SuperTruck 1. SuperTruck 2 enabled the ability to evaluate high risk high reward research centered on four areas that show the most potential for commercialization: aerodynamics, powertrain, rolling resistance and energy management. In addition, several industry, University and National laboratories were able to collaborate in developing technologies found to be successful in meeting the program objectives. Several technologies show promise towards production while some technologies do not show a quick path towards production.
