Reduce aerodynamic drag


The Trucking Industry's First Totally
Automated Trailer Air Spoiler

The SmartTail® aerodynamic fuel $ saving Air Spoiler is a rugged polymer skin transforming the trailer’s rear into a
more optimized aerodynamic profile to reduce drag and air vortex disturbances at the rear of the trailer.


SmartTail is Deployed or Stowed
Automatically While Driving

SmartTail - Reduce Aerodynamic Drag and Improve Fuel Efficiency

  • The SmartTail® state of the art Smart Control with onboard micro-computer and GPS automatically deploys the SmartTail® at factory pre-programmed speeds while driving.
  • At factory pre-programmed low speeds the Smart Control automatically evacuates the air spoiler polymer skins to fold & stow SmartTail® allowing the doors to be fully opened by the driver.
  • Totally automated operation eliminates any need for special driver duties
  • Save 4-7% in fuel $ without adding maintenance costs.
  • The cross linked fiber with slick polymer coated material for great aerodynamics, easy cleaning and resists snow/ice.
  • Triangular cross section is durable, mechanically stable and open bottom eliminates snow/ice buildup.
  • No external moving parts = no maintenance
  • Lightweight polymer skins are easily mounted with factory supplied stainless steel bolts and aluminum rails
  • SmartTail® in the stowed position folds and is compressed to about 3 inches when the doors are opened.
  • Adds insulating section for reefer applications

   Tested to SAE J1321 Type II

Savings calculated using SmartWay verified SAE type ii track test, Wind Tunnel tests and road data
Track tests performed by 3rd party - Continental Tire Oval track - Uvalde Texas
Uses a base tractor-trailer with 6.5 mpg before SmartTail® is added
Savings don't apply to fuel spent for idling and reduced at lower speeds

Smart Control

  • Smart Control is a self-contained state of the art control. It includes air blowers and a simple micro-computer and GPS. Speed, altitude, temperature, pressures and direction are monitored to automatically inflate and deploy the SmartTail® polymer skins while at higher speeds.
  • When low speeds are sustained for a time period, the control will automatically deflate and create a vacuum within the polymer skins to stow them, allowing the driver to simply open the rear doors normally without any additional duties
  • Contained within a rugged Stainless Steel frame that is easily mounted to the rear underside of the trailer
  • Only connection is to the trailer’s 12 volt circuit (no air or any other connection required)
    • Normal load is less than 100ma with 5 amp peak demand.
  • Control goes to sleep when tractor connection is powered off.
  • Unique features include automatic stowing if reverse direction of trailer is detected.
    • Eliminates any additional driver duties if backing into docks with rear doors closed.
