Exploring Our Innovation
Aeroflow is a Scotland based start-up focused on developing shape changing aerodynamic HGV trailers.
Worldwide, road haulage companies burn over £200 billion pounds of fuel annually towing empty/partially-loaded trailers. This inefficiency will only cut into haulier’s profits more over the coming years as the global road distribution market is still on the rise. Cutting even further into haulier’s profits is the implementation of various sustainable transport initiatives. These initiatives put pressure on companies to reduce their diesel consumption whilst simultaneously facilitating the transition to greener fuel alternatives.
Our aerodynamically efficient trailer provides a solution for hauliers that slashes costs, while helping to facilitate a greener future for the distribution industry. Designed for long-haul transit, our patented trailer design can cut aerodynamic drag to improve fuel efficiency by as much as 18%, translating to annual savings of over £4,500 per vehicle. This makes it a practical solution for both economic and environmental performance in long-haul freight transport.
How Our Technology Works
The universally recognisable box-truck shape is excellent for maximizing cargo capacity, but as we have discussed these behemoths are often towed less than fully loaded. In these cases, the boxy design becomes a massive source of drag, wasting fuel while not actively generating revenue.
Our solution is simple but powerful: when goods are unloaded from one of our trailers, the walls can be pulled together at the rear; pivoting until they meet at a point. This new profile significantly reduces aerodynamic drag. When the unused cargo space is needed again, the walls can simply be pulled apart again. It’s a flexible, smart design that adapts to your operations—so you only use the fuel you need.

Exploring Our Innovation
Worldwide, £200 billion is wasted on fuel every year by haulage companies transporting empty trailers. With the rise of delivered goods across the globe and increasing momentum towards more sustainable transport, rising pressures are being placed on haulage companies to reduce their diesel consumption whilst simulataneously transitioning to greener fuel alternatives.
Aeroflow is a Scottish-based start-up building aerodynamic HGV trailers that change shape to improve fuel efficiency—enhancing cost savings while reducing greenhouse gas emissions and extending range.
Designed for long-haul transit, our patented trailer design can cut aerodynamic drag to improve fuel efficiency by as much as 18%, translating to annual savings of over £4,500 per vehicle, making it a practical solution for both economic and environmental performance in long-haul freight transport.
How Our Technology Works
Traditional trailers are box-shaped to maximise cargo space—but they’re often driven empty or only partially loaded. In these cases, the boxy design becomes a disadvantage, creating drag and wasting fuel while the space inside goes unused.
Our solution is simple but powerful: we use that empty space to improve efficiency. The Aeroflow trailer features a shape-shifting design that allows the rear walls to taper inward when not fully loaded. This reduces aerodynamic drag, cuts fuel consumption, and lowers emissions. When maximum cargo space is needed, the trailer returns to its standard boxy form. It’s a flexible, smart design that adapts to your load—so you only use the fuel you need.
The Aerodynamic Edge
When air flows over a moving vehicle, it separates at the rear, creating turbulence and drag. An abrupt flat surface like the back end of a normal box trailer causes a large, sudden separation of airflow, resulting in a wide wake of turbulent air that manifests as drag that the vehicle must fight.
In contrast, providing a much shallower angle at the rear prevents the air from being torn away resulting in a dramatically reduced wake - and more importantly less wasteful drag. The tapered rear is especially beneficial for HGVs travelling at motorway cruising speeds, where over 50% of the fuel they consume is just to overcome drag.
Reducing the Rear Wake

The Aerodynamic Edge
A tapered rear significantly improves aerodynamic performance compared to a flat rear by reducing the size of the low-pressure wake that forms behind the trailer. When air flows over a moving vehicle, it separates at the rear, creating turbulence and drag.
A flat-ended trailer causes a large, abrupt separation of airflow, resulting in a wide wake of turbulent air that pulls backwards on the vehicle, increasing fuel consumption. In contrast, a tapered design allows the airflow to narrow gradually, reducing turbulence and allowing the air to close more smoothly behind the trailer.
By minimising drag, a tapered rear enables the vehicle to use less energy to maintain speed, especially at motorway cruising conditions where aerodynamic resistance is most pronounced.
