- The test session at Richmond Raceway wrapped up Tuesday afternoon. In addition to softer tires, NASCAR also experimented with completely eliminating the rear splitter and increasing rear spoiler heights.
- The Super DIRTcar Series stayed at Autodrome Drummond Tuesday night for the finale of the King of the North. Here, points leader Matt Sheppard led much of the race, but spun out of the lead with 26 laps to go after contact from David Hebert.
Mike Mahaney was able to get past Hebert for the lead on lap 59. From there, Mahaney was able to hold on to take the victory and lock himself into the 200-lapper at Oswego Speedway in October. Hebert was second, while Monday night's winner Erick Rudolph was third. Steve Bernard was fourth, while Mat Williamson was fifth. Sheppard recovered from his spin to finish ninth.
