Ford Developing Deployable Mud Flaps

Mud flaps are a straightforward component for cars and trucks, but Ford has come up with something a little more elaborate.

In a patent application published by the U.S. Patent and Trademark Office (USPTO) on February 20 (filed April 26, 2022), Ford details a deployable mudflap that moves outward from its stowed position to block splashing water from vehicle tires.

According to Ford, this system is primarily intended to keep the sides of the vehicle clean. If a significant amount of water spray is detected, the flaps deploy, preventing the water spray from hitting the sides of the vehicle and soiling everything.

Ford does not elaborate much on the advantages of deployable flaps as opposed to traditional fixed flaps. However, the automaker does mention that the door handles must be blocked to achieve the ideal spray-shielding position.

Aerodynamics may also be a factor. Ford has also patented deployable dive planes for the purpose of increasing aerodynamic tuning flexibility. However, dive planes are downforce generators typically used in performance cars, so their purpose is quite different.

As for what production vehicles (if any) will feature deployable mud flaps, we know that Ford plans to launch a new electric pickup truck in 2025. Codenamed T3, it is designed from the ground up as an EV, as opposed to the current Ford F-150 Lightning, which shares a platform with the gasoline-powered F-150 model.

Heavy trucks often come with mud flaps, but such a deployable version could help reduce aerodynamic drag and increase the range of the electric truck.
