Ram Is Working On Aero Bed Cover That Might Boost Truck Efficiency

Pickup trucks have a brick-shaped problem. Buyers want big cabs, tall beds, and tough styling, but all of that creates drag that hurts fuel economy and electric driving range.

Ram appears to be looking for a smarter way around that challenge. A recently published Stellantis patent shows an adjustable truck bed cover designed to improve airflow without giving up the utility pickup owners expect.

The concept works like a normal tonneau cover when flat, but it can also rise into different positions. In one mode, it creates a sloped fastback-like shape behind the cab to help air move more smoothly over the bed.

That sounds like a small change, but aerodynamics matter a lot at highway speeds. For gas trucks, it could mean better fuel economy; for electric trucks, it could help stretch range.

A Tonneau Cover With More Than One Trick

The patent describes a bed cover that can sit flat like a typical roll-top tonneau. In that position, it would protect cargo from weather and theft while allowing the bed to open when needed.

What makes the design interesting is its hidden support structure. Folding struts, arms, and linkages allow the cover to lift at different points, changing its shape depending on what the driver needs.

Raise the front section, and the cover forms a sloped roofline from the cab toward the tailgate. Raise both the front and rear sections, and it becomes closer to a full bed cap with extra enclosed cargo space.

That flexibility could make it more appealing than a traditional truck cap, which adds practicality but often hurts styling and can be awkward to remove. Ram’s idea keeps the bed cover integrated and adjustable.

Why Aerodynamics Are Important For Trucks

Open pickup beds create turbulence, which increases drag and forces the engine or electric motor to work harder. Automakers have spent decades trying to clean up airflow around trucks without compromising the basic shape customers expect.

A fastback-style bed cover could, theoretically, smooth the airflow behind the cab. That is the same general reason many EVs use sloped rooflines, even when the design creates styling trade-offs.

The benefit would likely be most noticeable during highway driving. At higher speeds, aerodynamic drag becomes one of the biggest enemies of efficiency, especially for large vehicles.

For future electric Ram trucks, even a modest improvement could make a difference. Range remains one of the biggest concerns for electric pickups, particularly when towing, hauling, or driving at freeway speeds.

The Real-World Gains Are Still Unclear

The idea sounds promising, but aerodynamic improvements are not always obvious in real driving. Something that looks slippery can still create unexpected turbulence if the shape is not carefully tested.

Past attempts to improve pickup efficiency have produced mixed results. Tailgate nets, aftermarket caps, and experimental fastback covers have not always delivered the gains owners expected.

That means Ram would need careful wind-tunnel and road testing before making bold claims. The concept may reduce drag in theory, but whether it saves enough fuel or range to justify the cost is another question.

Complexity could also be a hurdle. A movable cover with linkages and supports would likely cost more than a conventional tonneau, and pickup owners tend to value durability above cleverness.

It Could Fit Ram’s Future Lineup

Ram’s interest in active aerodynamics makes sense as the brand prepares for a more electrified future. The upcoming Ram 1500 REV and range-extended Ramcharger will both benefit from any feature that improves highway efficiency.

This design could also work as a factory accessory rather than standard equipment. That might allow Ram to offer it to buyers who want better efficiency or extra covered cargo flexibility without forcing it on every truck.

As always, a patent does not guarantee production. Automakers file plenty of ideas that never reach showrooms, sometimes simply to protect intellectual property.

Still, the fact that Stellantis keeps refining the concept suggests Ram has not abandoned the idea. Pickup beds may seem simple, but this patent shows there is still room to rethink even one of the oldest parts of a truck.
