Ford has started testing of the Maverick Rattler, an off-road focused model, as seen in these spy photos.

We can see that the prototype has a new front skid plate, FX4 sticker on the rear corners and independent rear suspension that confirms that this Maverick is AWD. There are likely many other off-road focused upgrades included here that can't be easily seen and we expect to learn about them soon.

The “Rattler” name was trademarked earlier this year hinting that a special-edition Maverick was in the works.
