The entry list also underscores the continued partnership between the series and a pair of prominent racing outfits, JR Motorsports and DGM Racing, both of which have confirmed their intent to field entries for the event.
A competitive landscape
The presence of 38 drivers suggests a highly competitive field, with teams likely to employ a mix of strategic approaches to contend on the 2.5‑mile oval, where drafting and pit strategy often dictate the outcome.
