Is now a good time to invest in aerodynamic technology for your vehicle fleet?
FlowBelow Aero Inc. has introduced a redesigned version of its Trailer AeroSlider system to improve vehicle efficiency. The modular kit uses fairings and wheel covers to reduce drag and boost fuel economy for long-haul trailers.
Why it matters
As diesel costs remain high, the system offers trucking fleets a path to lower operating expenses by improving fuel efficiency. The product is designed to pay for itself in under a year through consistent fuel savings.
The AeroSlider system weighs less than 30 pounds and can be installed on existing trailers in under 45 minutes. Testing by MVT Solutions confirms the fairings and mud flaps save 1.77 gallons per 1,000 miles, while wheel covers save 1.23 gallons.
The players
FlowBelow Aero Inc.
The company specializes in developing aerodynamic components for the trucking industry to improve fuel economy.
MVT Solutions
This firm provides independent fuel economy testing and technical validation for the freight transportation industry.
The details
The complete system consists of trailer wheel covers, flow-through mud flaps, and rear fairings that direct airflow away from the tandem to minimize turbulence. Engineers optimized the hardware through a combination of computational fluid dynamics, wind-tunnel trials, and track testing.
Timeline
FlowBelow first introduced the original AeroSlider in 2017.
Independent fuel economy testing occurred in June 2026.
Diesel prices reached a record $6.529 per gallon on September 21, 2026.
The national average diesel price was $6.179 per gallon on October 12, 2026.
The company showcased the system at the MCE conference from October 17-20, 2026.
Roadmap
This launch mirrors the industry-wide push to adopt drag-reduction technologies in response to the U.S. Environmental Protection Agency's Greenhouse Gas Emissions Standards for Heavy-Duty Vehicles. It positions FlowBelow as a key provider of modular solutions as fleets strive to meet federal efficiency requirements.
For fleet operators, the system offers a direct reduction in overhead costs by lowering diesel consumption during long-haul operations. With an estimated payback period of less than 12 months, the hardware provides a clear financial incentive for modernization.
The takeaway
Operators looking to maximize margins in the current fuel environment may benefit from assessing their trailers for aerodynamic upgrades. Implementing lightweight, bolt-on solutions can provide measurable financial relief without requiring significant vehicle downtime.
