Windyne Fuel Saving Fairings
Semi Trailer Aerodynamics

Semi Trailer Aerodynamics - Save Fuel

Welcome to Unprecedented Semi Truck Fuel Economy


Any fairing can claim to achieve semi trailer aerodynamics and fuel economy under optimized load conditions (such as testing in wind tunnels with the bogeys in the forward position to maximize trailer skirt coverage) but what happens to the claimed fuel savings in real-world, non-optimized conditions?

This is why Windyne’s patented Flip and Slide™ aerodynamic trailer side skirts were tested under various conditions over thousands of real-world miles recorded from customers who agreed to use their rigs as test vehicles. Meticulous data was kept! Despite varying conditions such as load positions, temperatures, weather, driving habits, terrain, and distance the Flip and Slide™ aerodynamic trailer side skirt still averaged 1 extra mile per gallon - with the most impressive savings being recorded by those who drove the furthest.

Why do Windyne Fairings perform So Well?


In a nutshell - Windyne’s patented Flip and Slide™ trailer side skirts provide full semi trailer aerodynamics by covering the underbelly of the trailer at all times.

Our side skirts, using innovative technology inspired by NASA, provide full trailer coverage and help to maximize trailer aerodynamics during all vehicle load positions.


Three key innovations ensure Flip and Slide™ trailer skirts
maintain maximum undercarriage coverage:


Aerodynamic Trailer Fairings - Patented Flip Feature
Fuel Savings
Flip Feature: Full Coverage and Full Access

More About Flip Feature

Flip Feature allows Full Vertical Coverage

Windyne's patented flip feature allows our fairings to vertically retract and flip up out of the way to avoid larger obstacles or when full access to the undercarriage is needed. This full access is akin to having a naked trailer. Vertical flip means the best of both worlds - maximum trailer coverage in the downward position and full trailer access in the upwards position. A full coverage fairing provides maximum semi trailer aerodynamics benefit which means maximum fuel and emission savings regardless of what challenges one may encounter in real world long-haul scenarios.

Slide Feature allows Full Horizontal Coverage

Windyne's patented slide feature allows our trailer fairings to horizontally slide (telescope) with the movement of the rear wheels - which means a full coverage fairing during all rear wheel and vehicle load positions. Full coverage of the trailer undercarriage maximizes trailer aerodynamics and means maximum fuel savings (and maximum emission savings) over the long-haul. A full coverage trailer fairing also allows the fairings to perform as side guard protection increasing safety to people, pets, cyclists, and other motorists.

Aerodynamic Trailer Fuel Economy - Flex Skirt Feature
Fuel Savings
Flex Skirt: Allows 4 Ground Inch Clearance

More About Flex Feature

Flex Skirt Contributes to Vertical Coverage

The flex skirt is a flexible molding that finishes the bottom of Flip and Slide™ trailer skirts and provides 4 inches of ground clearance. The flexible nature of the skirt yields to common obstacles such as curbs, sloped docks, uneven terrain and can avoid high centering. This feature allows normal truck and trailer operation for smaller obstacles without additional action. The trailer skirt can be flipped up (see above) for larger obstacles. The purpose of the flex skirt is to allow for maximum vertical coverage (lower ground clearance) - which means increased aerodynamic trailer benefit and increased fuel and emission savings.

Additional Savings


Windyne prides itself on great design, high-quality materials and craftsmanship to deliver a product and experience that is unmatched.

We believe that no detail is too insignificant and at Windyne excellence is always the standard. Every aspect of the Flip and Slide™ fairing has been carefully considered to deliver an exquisite final product using nothing but top-quality parts, materials and sturdy construction. Flip and Slide™ fairings are designed to last 10 years (under standard wear and tear and normal operating procedures) and some have lasted longer according to customer testimonials. Longer product-life increases profitability as fuel savings do not have to be reinvested in replacing fairings every few years.

"If you're in it for the Long Haul then it's time to enjoy some Real Fuel Savings!"

* Disclaimer:
Reported fuel savings of 1 mpg (235 L / 100 km) is a fair average in most long-haul driving situations - based upon real-world freight scenarios where data was meticulously recorded by numerous drivers across various terrains and weather conditions. However, individual fuel savings are dependent upon many factors including, but not limited to, driving habits; bogeys in the forward or rearward positions; long haul versus mid-range versus city driving scenarios; temperature: extreme heat or cold; weather conditions: wind, rain, snow, etc.; types of terrain, grade of slope, and load volume and type. For example, drivers may experience greater fuel savings over longer distances and lesser fuel savings during shorter trips and city driving. Despite these factors, users of Windyne Fairing Systems average 1 mile per gallon in fuel savings - no fixed fairing can outperform Windyne Fairing Systems in the same long-haul situations.
