Rivian is seeking to patent wheel covers with active aerodynamic elements to enhance the efficiency of its electric vehicles. These smooth wheel covers are currently available on the 2025 Rivian R1S and R1T models, but they are stationary and not optimized for all conditions. In a patent filing submitted to the USPTO in August 2023 and published in March 2026, Rivian discusses the concept of incorporating movable elements into the wheel covers to provide flexibility. The cover would include openings that align with wheel spokes in one position and block them to create a smooth surface in another, with a spring mechanism to facilitate movement between positions.
The active wheel covers proposed by Rivian offer not only an aesthetic choice for customers but also potential aerodynamic benefits. The covers could help to release built-up air pressure from the wheel wells, further enhancing aerodynamic performance. Additionally, when in the open position, the covers could assist in cooling, similar to the function of active grille shutters found on many current production vehicles. This innovative approach aims to improve efficiency and reduce drag on Rivian’s electric SUVs and pickup trucks, which typically have boxy shapes that present challenges in aerodynamic design.
Other automakers, such as Stellantis and Hyundai, have explored similar concepts to enhance aerodynamics on their vehicles. Stellantis patented a deployable rear step with an integrated diffuser for pickup trucks, while Hyundai tested an active air skirt that demonstrated a 2.8% reduction in the coefficient of drag on a Genesis GV60 SUV. This improvement equates to an estimated 3.7 miles of additional range on an electric vehicle. While these developments show promise in improving efficiency, there is no word yet on production plans for these active aerodynamic features.
The potential benefits of active aerodynamic elements on vehicles extend beyond aesthetics to practical considerations such as improved efficiency and range. Rivian’s patent filing for active aero wheel covers represents a step towards optimizing aerodynamics on electric vehicles, particularly those with larger and boxier body shapes that are traditionally less aerodynamic. By incorporating movable elements into the wheel covers, Rivian aims to provide customers with a practical and efficient solution that can adapt to different driving conditions and requirements.
In conclusion, Rivian’s pursuit of a patent for active aero wheel covers highlights the ongoing efforts within the automotive industry to improve efficiency and streamline aerodynamics in electric vehicles. By incorporating movable elements into the wheel covers, Rivian seeks to offer a versatile solution that can enhance aerodynamic performance while providing customers with aesthetic choices and practical benefits. As other automakers also explore similar technologies to reduce drag and improve efficiency, the future of electric vehicle design looks promising with the potential for more innovative and efficient solutions to be implemented. Overall, these developments in active aerodynamic elements represent an exciting step forward in enhancing the performance and range of electric vehicles.
