The sides of the vehicle feature extended racks to carry additional equipment, while the cabin features a higher, flatter profile, an additional front frame and a solid roof panel. While sharing the initial buggy design, the front features an additional frame bar behind the lights, while the upper front area is less angled than the Dune Buggy and has an extended panel on the driver side and a cut-out for the passenger-side turret. The Dune FAV is essentially a Dune Buggy modified for combat purposes.
The buggy appears to take strong inspirations from the Desert Patrol Vehicle (formerly known as the 'Fast Attack Vehicle'), although with a standard cabin instead of having a rear section for the rear gunner.
