MATS, LOUISVILLE, KY, -- A recent tractor-trailer aerodynamic study conducted by the University of Tennessee at Chattanooga’s National Center for Computational Engineering showed SmartTruck’s base-trailer aerodynamics system significantly reduces drag, translating into highway fuel savings of approximately 6%.
In additional testing using computational fluid dynamics conducted by CD-adapco and released in October 2013, SmartTruck's base UnderTray product was shown to reduce drag, producing highway fuel savings of approximately 7%.
Both UT-C and CD-adapco are recognized as leaders in the aero testing and evaluation fields.
“SmartTruck has contended for several years that the trucking industry has the opportunity to better understand the intricacies of aerodynamic testing and the need for a variety of test methods to guarantee accurate results that will coincide to real-world applications,” said Henderson. “Our belief is being borne out by recent movements by the EPA to include a broader palette of testing methods for verifying products under the SmartWay program—methods that include SAE J1321, wind tunnel testing, CFD and coastdown testing.”
SmartTruck has also contracted an additional world-renowned, third-party testing organization to conduct SAE J1321 testing on its products to further confirm the company’s product performance. Testing is scheduled to take place in the coming months.
