The new testing included an autonomous route, which was tested for mobility and demonstration, including sensor point cloud visualizations.

The agile and fast tank utilizes the Textron M5 base platform, which was previously developed and used in US Army campaigns of learning for robotic combat vehicle requirements and acquisition. The fourth experiment of RACER was performed by teams from the University of Washington and from NASA's Jet Propulsion Laboratory (JPL). DARPA remarked that RACER is on track to continue its autonomy development and experiment spirals with a new round of testing roughly every six months.
