Xfinity / O'Reilly Auto Parts Series (1982–present)

NASCAR's second-tier national series, often considered a proving ground for drivers aspiring to reach the Cup Series. It debuted in 1982 as the Budweiser Late Model Sportsman Series and has carried the names of several title sponsors: Busch Series (1984–2007), Nationwide Series (2008–2014), Xfinity Series (2015–2025), and the O'Reilly Auto Parts Series (2026–present).

nxs <- load_series("nxs")

The series identifier is "nxs", NASCAR's own sponsor-neutral abbreviation. This avoids tying the code to any single title sponsor.

Truck Series (1995–present)

The NASCAR Craftsman Truck Series features modified pickup trucks racing on a mix of ovals, short tracks, road courses, and dirt tracks. It launched in 1995 as the SuperTruck Series and has been sponsored under the names Craftsman Truck (1995–2008), Camping World Truck (2009–2022), and Craftsman Truck again (2023–present).
