In the first five weeks of the season the Gen-6 car is being tested on all sorts of tracks. From the Superspeedway of Daytona to the short track at Bristol. This week NASCAR heads back out west to the two-mile Auto Club Speedway in California. It’s the first of two visits there this season.

Tony Stewart was the winner of a rain-shortened race last year after running 258 of 400 miles. Kyle Busch came in second.

Last week at Bristol a lot of attention was focused on what appears to be a growing feud between Denny Hamlin and Joey Logano after a couple of incidents on the track. Logano confronted Hamlin after the race and he was pushed away by Hamlin’s crew members and that caused some pushing and shoving between crew members of both teams. It’ll be interesting to see what happens this week.

El Cajon, California native Jimmie Johnson considers this his home track and among active drivers he has the most wins there with five. He also has the most Top-5 finishes with 12. Jeff Gordon and Matt Kenseth each have three victories at the track.
