Deployable rear step featuring a diffuser could enhance effectiveness for electric trucks

Ram, a subsidiary of Stellantis, is considering utilizing a unique and innovative feature on its future electric pickup trucks to enhance both aerodynamic efficiency and practicality. This feature involves combining a deployable rear step with an active diffuser, a concept that has not been seen in production vehicles before. The patent application for this technology, filed by Stellantis in December and published in July, describes it as a “vehicle rear step and diffuser system.” While active diffusers are not a new concept, integrating them into a multifunctional rear step could offer significant benefits for electric vehicles in terms of range and overall performance.

### Enhancing Efficiency With a Dual-Purpose Design
Rear diffusers are commonly used in high-performance vehicles to increase downforce and reduce drag, ultimately improving grip and efficiency. By incorporating a diffuser into the underside of a deployable rear step, Ram aims to not only aid in aerodynamic performance but also provide a convenient access point to the bed of the pickup truck. The patent outlines that the bottom surface of the step would be shaped as a diffuser, while the top surface would function as a flat step for easy access. This dual-purpose design allows the diffuser to be stowed when not in use, preventing any protrusions from the rear bumper at lower speeds.

### Suitable for Body-On-Frame Construction
The patent specifies that the deployable diffuser and step system is intended for vehicles with body-on-frame construction, such as Ram’s popular pickup trucks, including the upcoming 2025 Ram 1500 REV model. The drawings included in the patent application depict a rear tailgate of a pickup truck, highlighting how the design could be incorporated seamlessly into the vehicle’s overall aesthetics. This feature aligns with Ram’s commitment to innovation and sustainable transportation solutions, paving the way for more efficient electric vehicles in the future.

### A Glimpse into Future Design Concepts
While the Ram 1500 Revolution BEV concept showcased a similar design, it is important to note that this concept may not be heading into production. However, it serves as a glimpse into the potential design direction for Ram’s upcoming electric trucks, suggesting that elements like the active diffuser and step combination could become a reality in future models. By exploring new technologies and merging them with practical solutions, Ram is positioning itself as a leader in the evolving landscape of electric vehicle development.

### Embracing Innovation for Sustainable Mobility
In today’s automotive industry, the push towards sustainability and energy efficiency is steering manufacturers towards innovative solutions like the deployable diffuser and step system proposed by Ram. By integrating aerodynamic features with functional components, vehicles can achieve better performance while reducing their environmental impact. Stellantis’ patent for this novel technology exemplifies a commitment to embracing change and adapting to the evolving needs of consumers, especially in the context of electric vehicles and their unique requirements.

### Conclusion
In conclusion, Stellantis and its subsidiary Ram are leading the way in cutting-edge vehicle design with the introduction of a deployable diffuser that doubles as a bed step for future electric pickup trucks. This innovative feature not only enhances aerodynamic efficiency but also offers practical benefits in terms of accessibility to the truck’s bed. By combining active aerodynamics with functional design elements, Ram is poised to revolutionize the electric vehicle market and set new standards for sustainability and performance. With a focus on innovation and forward-thinking solutions, Ram continues to drive the industry towards a more sustainable and efficient future.
