Martin Truex Jr. Secures Victory at Sonoma NASCAR Cup Series.
The Next Gen car performed well on the road course at Sonoma Raceway, leading to a relatively uneventful race with only one caution. Martin Truex Jr. won the race, his second win of the season and third win in the last five Sonoma races. NASCAR is cracking down on illegal parts for the Next Gen car, with some teams already penalized and publicly displaying counterfeit parts. Drivers have mixed feelings about the lone off-weekend in the 38-race schedule, with some planning to vacation and others using the time to prepare for upcoming races.
