What You'll Learn
Airtab's unique wishbone shape
Airtabs are patented, uniquely shaped vortex generators designed to increase vehicle performance and fuel economy. Their wishbone shape is specifically designed to reduce aerodynamic pressure drag at two key locations: the tractor-trailer gap and the rear-facing surface (the base area) of any commercial or private square-backed vehicle or trailer that routinely attains highway speeds.
The wishbone shape creates two tight swirls of air that combine to reduce suction and drag. Each Airtab creates a series of vortices that combine to reduce the drag at the rear of vehicles travelling at speeds above approximately 35 mph or 55 km/h. This not only reduces fuel consumption but also provides safety benefits.
The Airtab wishbone shape is designed to reduce drag and increase fuel economy for vehicles travelling at highway speeds. The unique shape of the Airtab creates vortices that keep the airflow attached to the vehicle, preventing it from separating and causing drag. This is especially beneficial for vehicles with square backs, as the airflow at the rear of these vehicles can create a low-pressure area that increases drag and fuel consumption.
The Airtab wishbone shape is a simple yet innovative design that helps improve fuel efficiency and vehicle performance. By reducing drag and optimising airflow, Airtabs can help vehicles maintain highway speeds while using less fuel. This not only results in cost savings for vehicle owners but also contributes to a reduction in carbon emissions, making it a more environmentally friendly option.
While the Airtab wishbone shape is designed to improve fuel economy, the actual fuel savings may vary depending on the vehicle type and other factors. Some users have reported an increase in fuel mileage of around 1.8 mpg, while others have noted that the impact on fuel efficiency may be minimal for certain vehicle types.

Airtab's impact on vehicle stability
Airtabs are designed to improve vehicle stability and reduce fuel consumption. They are wishbone-shaped plastic moulds that are placed on the sides and roof of a vehicle. Airtabs create two tight swirls of air that combine to reduce suction and drag at the rear of the vehicle, particularly at the tractor-trailer gap and the base of any square-backed vehicle or trailer. This reduction in drag leads to improved fuel efficiency.
Testing by Millbrook Proving Grounds and MIRA in the UK found that Airtabs can reduce fuel consumption by between 3% and 5%. Additionally, Airtabs provide safety benefits, including increased vehicle stability in high winds. This is due to the altered airflow around the vehicle, which reduces the impact of crosswinds and other external forces that can affect the stability of the vehicle.
The impact of Airtabs on vehicle stability is particularly notable for vehicles with large side profiles, such as cube vans, SUVs, RVs, buses, and various types of trailers. By reducing the drag and optimizing the airflow around these vehicles, Airtabs help improve their stability, especially at high speeds. This can lead to a more comfortable and controlled driving experience, as well as improved safety for the driver and other road users.
Furthermore, Airtabs can enhance stability in vehicles with a rear window slope of greater than 30 degrees. In these cases, Airtabs are placed at the rear roofline to modify the airflow and reduce drag, resulting in improved stability and fuel efficiency. The number of Airtabs required depends on the size of the vehicle, with a recommended placement of three per running foot.
Overall, Airtabs impact on vehicle stability is a crucial aspect of their design and functionality. By reducing drag and modifying airflow, Airtabs not only improve fuel efficiency but also enhance the stability and safety of a wide range of vehicles, especially those with large side profiles or specific rear window designs. This technology demonstrates how innovative solutions can lead to both economic and safety benefits in the transportation industry.

Airtab's safety benefits
Airtabs are plastic moulds that reduce aerodynamic drag on vehicles. They are placed on the sides and roof of a vehicle, with three per running foot. Airtabs create two tight swirls of air that reduce suction and drag at the rear of a vehicle travelling at speeds above 35 mph. This results in reduced fuel consumption, with tests showing an average reduction in fuel consumption of between 3% and 5%.
Airtabs also provide several safety benefits. Firstly, they improve vehicle stability in high winds. This increased stability makes driving safer and reduces the risk of accidents. Additionally, Airtabs can reduce spray, improving visibility for the driver and other vehicles on the road. This is especially beneficial in wet weather conditions.
The reduction in drag also has safety benefits for other vehicles on the road. By reducing drag, Airtabs help to improve the fuel efficiency of the vehicle. This leads to reduced fuel consumption and lower CO2 emissions. Lower emissions contribute to improved air quality, which has a positive impact on the environment and human health. Improved air quality can reduce the risk of respiratory issues and other health problems associated with air pollution.
Furthermore, Airtabs can enhance driver safety by reducing wind drag. The LCS GR8LOOK bulkhead, for example, was designed with a tarp colour-matching fibreglass moulded top fairing. This design reduces wind drag and provides a more stable pulling trailer for the driver. Overall, Airtabs offer a range of safety benefits that contribute to a safer driving experience and a more environmentally friendly vehicle.

Airtab's application on different vehicles
Airtabs are uniquely shaped plastic moulds that can be applied to different vehicles to improve fuel economy and performance. They are designed to reduce drag and improve stability, and can be used on any vehicle with a rear slope of more than 30 degrees. This includes trucks and trailers, box vans, and RVs.
Airtabs work by creating a controlled vortex of air, which reduces wind resistance and drag. Each Airtab creates two counter-rotating vortices of air, several feet in length, that smooth the airflow around the vehicle. This is particularly effective in reducing drag at the tractor-trailer gap and the base area of square-backed commercial vehicles.
The application of Airtabs can result in a fuel consumption reduction of between 3% and 5%, as tested by Millbrook Proving Grounds and MIRA in the UK. This not only improves fuel efficiency but also provides safety benefits. For example, Airtabs can reduce spray, improving visibility for the driver and other vehicles in wet or snowy conditions. They also reduce the accumulation of road grime, ensuring tail lights and reflectors remain clean and visible, and reducing snow buildup.
Airtabs are designed to be easily installed and applied to any suitable vehicle. Their versatility and effectiveness in reducing drag and improving fuel economy make them a valuable addition for commercial fleets and personal vehicles alike.

Airtab's impact on wind drag
Airtabs are designed to reduce wind drag, which in turn improves fuel efficiency. They are wishbone-shaped vortex generators that create two tight swirls of air, reducing suction and drag at the rear of a vehicle. This is particularly effective at the rear rooflines of cars with a rear window slope of more than 30 degrees.
Airtabs are placed at two key points on a vehicle: the tractor-trailer gap and the base area of any square-backed vehicle or trailer. They are not limited to commercial transportation vehicles and can be used on a variety of vehicles, from cube vans to SUVs, RVs, buses, and trailers.
The impact of Airtabs on wind drag is significant. Tests have shown that Airtabs can reduce wind drag by up to 12%, with an average reduction in drag of between 3% and 5% for vehicles traveling at speeds above approximately 35 mph (55 km/h). This reduction in wind drag leads to improved fuel efficiency, with a corresponding reduction in fuel consumption of between 3% and 6%.
The exact number of Airtabs required depends on the size of the vehicle. They are typically placed at a rate of three per running foot (4" on center) and spaced according to the specific vehicle's measurements.
