United Autosports USA is the only two-car entry, while teams like CrowdStrike Racing by APR, Tower Motorsports, and Intersport Racing will each field a single car. Notable newcomers include Intersport, Bryan Herta Autosport, and Team Tonis, the latter stepping up to a full-time effort after their debut at Road America.
