Mesilla Valley Transportation Solutions, a provider of breakthrough fuel economy testing and design and development services for the trucking industry, announced today the results of testing on the Streamliners Miniskirt with Eco Flaps. The device provided fuel savings of 2.65 gallons per 1,000 miles, or 2.37%. The Miniskirt is a unique alternative to a traditional side skirt and is a short rear-mounted device.

“The Miniskirt was California (CARB) certified in 2021,” said Joe Hamm, President and CEO of Streamliners. “Our next step was to further validate its performance with on-road testing. MVT Solutions is the industry leader in providing high-confidence, real-world fuel economy testing, so we chose to work with them.”

The testing was completed in November of 2021 with two vehicles running simultaneously at 65 mph around a 9-mile circle track near Pecos, Texas. The test vehicles were 2019 International LT 625s with Cummins X15 15-liter engines and Eaton Endurant 12-speed automated manual transmissions. Trailers were 53-foot Hyundai dry vans. Gross vehicle weight for each vehicle was approximately 45,000 lbs. Both vehicles utilized dual tires and 24-inch width mud flaps. One vehicle had the Streamliners Miniskirt installed; the other did not. Eco Flaps were installed on the trailer only.

“MVT Solutions testing of the Streamliner Miniskirt with Eco Flaps showed a fuel economy improvement of 2.65 gal/1000 miles (2.37%),” said Daryl Bear, lead engineer and chief operating officer at MVT Solutions. “This can be considered substantial fuel savings in placement of trailer skirts,” he added. According to Hamm, “The test MVT Solutions performed confirmed and validated our existing data and along with our California certification, should give operators the confidence they need in considering the Miniskirt for their fleets.”

Hamm says that while the test was on a dry van, the Miniskirt can be installed on flat beds, tankers, dump trailers and intermodal chassis. “We believe our product will provide aerodynamic savings on those types of trailers as well.”
