Sustainable Transportation Day showcases advanced diesel technologies

The latest fuel savings and near-zero emissions technologies were showcased at Sustainable Transportation Day, hosted by the U.S. Department of Energy on Monday in Washington, D.C., at the National Mall.

Freightliner’s SuperTruck was one of the main features, as it more than doubles fuel economy for a heavy-duty Class 8 tractor running a diesel engine.

"The Class 8 tractor on display today demonstrates that diesel is a sustainable technology today and will be an integral part of achieving our clean air, climate and energy savings goals," Allen Schaeffer, executive director of the Diesel Technology Forum, said. "Advanced engine technologies showcased in Freightliner's SuperTruck significantly improve engine efficiency by 50 percent. Other technologies including advanced aerodynamics, lightweight materials and others will further help improve the ability of the diesel engine to move goods using less fuel.

"While the vehicle on display today demonstrates the capability of technology to further improve fuel economy, advanced technologies are already on the road today delivering substantial clean air and fuel savings benefits," Schaeffer said. "These significant benefits come after more than a decades' worth of investments in innovation by heavy-duty vehicle and engine manufacturers. Manufacturers have deployed fuel savings technologies along with advanced near-zero emission technologies that have saved 21 million barrels of crude oil and reduced carbon emissions by nine million tons since 2010, while eliminating 1.5 million tons of emissions of oxides of nitrogen."
