NASCAR’s premier Cup Series is set to descend on Sonoma Raceway this weekend for the Toyota/Save Mart 350, a 12‑lap road‑course showdown that will unfold on Sunday, June 28, with practice and qualifying slated for Saturday.
In‑Season Challenge: A Knockout Bracket
The event is part of the series’ In‑Season Challenge, a knockout‑style bracket that pits 32 drivers against one another for a share of a modest cash prize, adding an extra layer of stakes to an already competitive field.
Thirty‑six drivers are slated to take the green flag, among them reigning champion Kyle Larson and 2023 Sonoma winner Shane van Gisbergen, who enter as the clear favorites according to analysts and betting markets.
Tyler Reddick and the emerging Connor Zilisch are also mentioned as strong contenders, while veteran Daniel Suárez and past victor Kyle Larson have historically performed well on the twisty layout.
Austin Hill will step in for the injured Kyle Busch at Richard Childress Racing, and the lineup will feature a mix of established teams such as Trackhouse Racing and Team Penske.
Beyond the on‑track action, the race is backed by a roster of sponsors ranging from Kubota Tractors to Monster Energy, illustrating the event’s deep commercial ties.
