Mesilla Valley Transportation Solutions, a provider of fuel economy testing and design and development services for the trucking industry, announced test results for The NextGen EkoStinger, an aerodynamic fairing for Class 8 tractor-trailers. It is a one-piece design made with polyethylene that sits underneath the trailer in front of the rear wheels and slides with varying tandem positions. Testing in November 2021 demonstrated that the technology resulted in a fuel savings of 5.72 gallons per 1,000 miles or 5.30%.
Tests were conducted on 2019 International LT 625 with Cummins X15 15L engines and Eaton Endurant 12-speed automated manual transmissions pulling 53’ Hyundai dry vans. A baseline test was run without the aerodynamic NextGen EkoStinger on the trailer and then the aerodynamic device was installed, and the test runs again. Note: The EkoStinger used in the test was a prototype unit.
