OGAB® ROAD Advanced TRS®

Utilising patented Active Flow Control technology, Ogab® has developed a breakthrough system that reduces aerodynamic drag on commercial vehicles, thereby offering the possibility to significantly increase their fuel efficiency.

At speeds of 70mph+ aerodynamic losses can account for up to 70% of the power demand from the engine. Changing the vehicle power source whether it is fuel, hybrid or electric will not reduce power consumption.

To reduce power consumption, we must resolve this critical issue of aerodynamic drag.

With our breakthrough research, we have achieved unprecedented reductions in drag coefficient on mid-sized commercial vehicles and HGVs by up to 41%. This results in a significant increase in HGV MPG (miles per gallon) capabilities.

Our Advanced TRS® technology, which is powered by energy that would otherwise be lost, not only offers lower fuel related costs, it also improves overall vehicle performance and offers a significant reduction in carbon emissions.

In addition to this, the technology reduces the long-term operational demand on the engine, extending the vehicle’s lifespan as a result. 

Read on to learn more on how we achieved these game-changing results…


Environmental concerns, resource scarcity and excessive cost of fossil fuels have obligated governments and industries to reduce the greenhouse gas emissions and deploy effective fuel saving strategies in various industrial sectors. The transportation sector is one of the most energy-intensive industries and is responsible for a substantial portion of the global CO2 footprint.

Vehicle manufacturers seek for novel techniques and solutions to reduce the road resistance of the motor vehicles and hence the fuel consumption and GHG emissions. This resistance consists of a mechanical part as well as an aerodynamic facet. For a highway environment, in which most commercial goods are shipped, aerodynamic losses which are dissipative and cannot be recovered are the dominant source for power and fuel consumption. 

Therefore, our researchers have explored various active and passive flow control strategies to reduce the aerodynamic drag.

At stop-and-go speeds, drag isn’t significant, but the faster you go, the more it matters. At 70 mph, a vehicle will be overcoming four times the aerodynamic drag compared to the same vehicle at 35 mph.
