Overview

  • The Toyota/Save Mart 350 is scheduled for Sunday, June 28 at 3:30 p.m. ET with live coverage on TNT and HBO Max.
  • Organizers published a 36-car Cup entry list that fills the permitted field, meaning no teams will fail to qualify and Corey Heim’s No. 67 is not entered this weekend.
  • The race is 110 laps (218.9 miles) run in three stages of 25, 30 and 55 laps, a format that rewards pit strategy and road-course skill.
  • Shane van Gisbergen is the defending Sonoma winner and enters as the odds-on favorite in early betting markets, with DraftKings listing him around -150.
  • Sonoma opens NASCAR’s five-week In-Season Challenge, a head-to-head bracket competition that adds a midseason prize and raises the race’s impact on playoff positioning while ARCA West and the O’Reilly series run companion events Friday and Saturday.
