Fontana was filled with cautions, and was a race that did not agree with tires.
Several drivers including Dale Earnhardt Jr. and Kevin Harvick ran into tire problems early on, and had to battle back from being at the end of the pack. Kevin Harvick was able to recover from his first flat tire and made it up to third place when he had another tire go down and put him a lap behind.
Fontana also saw a lot of lead changes as drivers seemed to always pit during caution flags for new tires.
Brad Keselowski started out the race extremely dominant. He had the fastest car on the track, but he ran into tire issues and was never able to recover.
Jimmie Johnson, Matt Kenseth, and Jeff Gordon were all up front at one point during the race, and were the three most dominant cars for most of the Auto Club 400.
Restarts were important, but the driver who started out in front during a restart often had trouble staying there as the race continued to go green.
Overall nine cautions came out, and most were related to tire issues.
Jimmie Johnson won at Fontana five times leading up to this race, and his dominance at the track continued as he lead the most laps.
With 50 laps to go his lead grew on Matt Kenseth and Jeff Gordon. The longer the race stayed green though, the better Jeff Gordon's car performed.
The last caution of the race came out around Lap 33, and we went green for the last time at Lap 27. Jimmie Johnson continued to dominate on restarts, but Jeff Gordon was able to catch him after several green laps.
It looked like Gordon had a real chance to pass Johnson, but somehow the six time champion was able to hold back the 24 car, and was ready to make it to victory lane until he had a tire go down with only eight laps to go.
Than Brad Keselowski, Marco Ambrose, and Clint Bowyer all had tires go down as well, which eventually brought out the final caution of the day, and the green-white checkered.
After drivers headed to pit road for the last time, Kurt Busch and Landon Cassill started on the front row.
As the GWC start began, it was Kyle Busch and Kyle Larson who stood out as the race came down to one Lap left.
Busch was able to push to the front, but Kyle Larson gave him a hand full as he battled Busch for the lead. It was an extremely impressive rookie run, but it wasn't enough to get passed Busch.
Kyle Busch continues the winners streak, and we've had five drivers now who have all locked themselves into the Chase.
Winner at Fontana: Kyle Busch
