Tatuus IP-22 | Tatuus USF-22 | Tatuus JR-23 Specifications

The same base Tatuus chassis is utilized in all three levels of USF Pro Championships, allowing drivers and teams to begin with the USF Juniors JR-23 and continue to advance up the world’s most complete driver development system with a forward-thinking three-step concept.

The equipment package will remain in competition for at least three more seasons through 2027.

Chassis

Tatuus is world-renowned as a premier builder of formula cars. The USF Pro Championships concept is unique in that the same monocoque and many of the main suspension and bodywork components are common to all three series.

The chassis is a full carbon composite and aluminum honeycomb monocoque meeting current FIA safety standards including side impact panels, front and rear impact structures, HANS-compliant INDYCAR head restraint, front and rear wheel tethers and an upgraded front bulkhead structure for USA-specific oval racing circuits and a Halo-type device.
