The XP-38 All-Terrain Roughrider produced by SoroSuub Corporation was an updated version of the XP-38 sport landspeeder, modified for use on rough terrain.

It was similar in design to the earlier X-34; in fact, it looked much like a slim version of this older model. Its engines were similar to the Flash speeders of Naboo.

This updated, sleeker model was a popular civilian speeder, and was also often used by Imperial forces as a support vehicle at planetary garrisons.

The XP-38 sport landspeeder was released shortly before the Battle of Yavin and customers soon found that its repulsorlift system made travel over rough terrain quite difficult. This modified version corrected that problem.

The release of this updated speeder lowered the resale value of the earlier X-34.
