Rivian is seeking a patent for wheel covers with active aerodynamic elements to enhance the efficiency of its electric vehicles.
Traditional smooth wheel covers, like those found on the updated 2025 Rivian R1S and R1T models, can reduce aerodynamic drag. However, they are typically fixed in place and not adaptable to various scenarios. Rivian’s patent filing, submitted to the USPTO in August 2023 and published on Mar. 6, introduces the concept of movable aero wheels with flexible elements for increased functionality.

Rivian’s innovative wheel cover design features openings that align with wheel spokes in one position and block them for a smooth surface in another. This movement is actuated by a spring that rotates the cover to different positions.
Besides offering customers the choice of covered or uncovered wheels without removal, Rivian suggests that active wheel covers could help release built-up air pressure from wheel wells, enhancing aerodynamic performance. When open, the wheel covers could also provide a cooling function similar to active grille shutters on current production cars.

The boxy shapes of SUVs and pickup trucks pose challenges in minimizing drag. Other automakers, such as Stellantis with its deployable rear step and Hyundai with its active air skirt, are exploring active aerodynamic solutions. Hyundai’s tests with the Genesis GV60 showed a 2.8% reduction in drag coefficient, equivalent to an estimated 3.7 miles of additional range.
