Daimler Trucks reaches SuperTruck milestone

DTNA is focusing on a multitude of areas that impact freight efficiency, including aerodynamics, powertrain integration, weight reduction, energy management, reduction of parasitic losses, electrification of components, and hybridization. To date, the program has worked through development and testing phases from computer modeling to component bench testing, and most recently, in vehicle validation.

PORTLAND, Ore.  — Daimler Trucks North America (DTNA) last week said it has completed Phase One of its SuperTruck program.

In this initial phase — which marks the halfway point of the program — 25 percent freight efficiency has been validated “in real world testing conditions,” Daimler officials said.

Sponsored by the Department of Energy (DOE) under the American Recovery and Reinvestment Act of 2009, DTNA and other project partners including national labs, universities and suppliers are examining opportunities that significantly improve freight efficiency, reduce fuel consumption and greenhouse gas emissions of Class 8 trucks.

DTNA is focusing on a multitude of areas that impact freight efficiency, including aerodynamics, powertrain integration, weight reduction, energy management, reduction of parasitic losses, electrification of components, and hybridization. To date, the program has worked through development and testing phases from computer modeling to component bench testing, and most recently, in vehicle validation.

“The validation of our results point mainly to improvements found in aerodynamics, smarter vehicle control systems and powertrain enhancements including hybridization,” said Dr. Maik Ziegler, director of advanced engineering, Daimler Trucks North America. “The reduction of parasitic losses, rolling resistance and vehicle weight are other essential parameters, which are necessary to reach such an aggressive target.”

“Based upon what we have already achieved at this halfway point, and what has been modeled with future concepts, we are well on the way to achieve our 50 percent freight efficiency target on time,” said Derek Rotz, principal investigator for the SuperTruck vehicle program at Daimler Trucks North America.

“Our involvement with the SuperTruck program is synonymous with DTNA’s longstanding commitment to developing advanced solutions to reduce fuel consumption and ultimately contribute to our customers’ total cost of ownership,” said TJ Reed, director, product strategy for Freightliner Trucks. “DTNA has paced the market with recent introductions and will continue in our role as the leader in developing technologies that positively impact the industry.”

Many of the concepts developed with the SuperTruck such as an integrated powertrain, 6x2 optimization and enhanced aerodynamics have already been transferred to the market through recent introductions such as the Freightliner Cascadia Evolution, which delivers top fuel economy performance.

DTNA began work on the SuperTruck program in 2010 and is collaborating with Detroit Diesel Corporation and other partners to meet the program objectives by

2015. DTNA is now producing the concept SuperTruck vehicle that will be the next phase of total system testing.
