Technical Session #1

ATA’s Technology & Maintenance Council (TMC) and SAE International are once again teaming up to present the TMC/SAE Symposium, which this year is focusing on the latest findings from the U.S. Department of Energy’s (DOE) SuperTruck II program, as well as offering a sneak peak at what industry can expect from the soon-to-launch SuperTruck III.

The Symposium will feature presentations by advanced engineering executives from the major project teams and lead OEMs: Navistar, Volvo, Cummins/Peterbilt, and Daimler. Following this plenary session, attendees be able to ask additional questions, “kick the tires” and examine the advanced technologies on TMC’s exhibit floor where SuperTruck II vehicles and related technologies will be on display in a special pavilion.

The 21st Century Truck Partnership (21CTP) is a focal point for the project, coordinating the efforts of four federal agencies, 15 OEMs, and various component suppliers with the common goal of making trucks safer, cleaner, and more fuel efficient. Primary funding comes from DOE which supports four OEM teams in the development of Class-8 tractor-trailer systems to demonstrate improvements in freight efficiency over production vehicles. During our session, these development teams will present their design strategies and performance results and discuss the efficient optimized powertrains, advanced aerodynamics, and many other features that are moving into production. The goals for SuperTruck II were ambitious, which challenged Daimler, Volvo, Cummins/Peterbilt, Navistar and PACCAR to demonstrate a 55 percent engine brake thermal efficiency (BTE) at 65 mph — five percent higher than SuperTruck I.

Other targets included a greater than 100 percent improvement in vehicle freight efficiency (on a ton-mile-per-gallon basis) relative to a 2009 baseline for a long-haul freight application, and the development of cost-effective efficiency technologies. All teams proposed freight efficiency targets ranging from 120 to 140 percent improvement, and will share their results with attendees.

Panelists will also shed light on what to expect from SuperTruck 3, which DOE is providing more than $160 million in funding for projects to electrify medium- and heavy-duty freight trucks, boost vehicle efficiency, and expand electric vehicle infrastructure. The funding focuses on a range of approaches to electrification—all-electric, plug-in hybrid systems using renewable biofuels, and hydrogen and fuel cell technologies, including hybridization strategies such as fuel cell range extenders.

Attend this session and learn what progress has been made for the next generation of truck technology, and what plans are in the works to aggressively cut down carbon emissions by 2050 to bring commercial vehicles to a net-zero state.
