Rivian is trying to patent wheel covers with energetic aerodynamic parts to additional enhance the effectivity of its electrical automobiles.
Easy wheel covers—like those obtainable on the up to date 2025 Rivian R1S and R1T—may also help cut back aerodynamic drag, however they’re usually mounted in place, and thus not optimized for all situations. In its patent submitting, which was submitted to the USA Patent and Trademark Workplace (USPTO) in August 2023, however solely revealed by that workplace Mar. 6, Rivian discusses giving aero wheels movable parts to realize flexibility.

As described by Rivian within the submitting, the wheel cowl would come with a collection of openings aligning with wheel spokes when the duvet is in a single place, and block them to create a easy floor in one other. That motion can be actuated by a spring, which might rotate the duvet to completely different positions.
Along with giving prospects the aesthetic alternative of lined vs. uncovered wheels with out having to take away something, Rivian suggests within the submitting that energetic wheel covers may assist evacuate constructed up air strain from the wheel wells—additional bettering aerodynamic efficiency. Of their open place, the wheel covers may additionally serve a cooling perform, in response to the automaker, much like the energetic grille shutters on many present manufacturing vehicles.

The boxy shapes of SUVs and pickup vans like Rivian’s electrical off-roaders presents a problem in minimizing drag. That is led different automakers to contemplate some elaborate energetic aerodynamic aids, such because the deployable rear step with an built-in diffuser for pickup vans patented by Stellantis.
Hyundai has additionally examined an energetic air skirt that the automaker believes may very well be useful in lowering drag in SUVs, or any electrical automobiles with wider wheels. The automaker mentioned in 2024 that checks utilizing a Genesis GV60 from its luxurious model confirmed a 2.8% discount within the coefficient of drag, price an estimated 3.7 miles of vary. However to date Hyundai hasn’t mentioned manufacturing plans.
