The Nationwide Series started its 2012 season at Daytona. The race was dominated by a mix of tandem and pack drafting. On the final lap, Kurt and Kyle Busch attempted to block the tandem ofJoey Logano andTrevor Bayne. When the Busch brothers moved up to block, it resulted in a 10 car collision that wrecked most of the top 10. Part-time Nationwide driverJames Buescher sailed through the wreck and scored his first series win. Heading to Phoenix,Kevin Harvick dominated the race, leading 90 laps. On the final pitstop, teammate Sadler got two tires and managed to hold off a chargingBrad Keselowski for his first Nationwide win in 14 years. Heading to Las Vegas, defending championRicky Stenhouse Jr. held off veteranMark Martin for his first win of the season. The next week at Bristol, polesitter Logano dominated the race, leading 119 laps. But Elliott Sadler, on the advice of crew chief Luke Lambert, stayed out during the final round of pit stops and held offKasey Kahne for his second win in four races. In California, Logano won back-to-back poles, but held off Stenhouse for his first win of the season.

Following the off week, teams returned to racing at Texas. There, Stenhouse andPaul Menard were the class of the field, with Menard leading 100 laps.

At the second race in Iowa, polesitter Elliott Sadler rebounded from the disappointment at Indy and held off Justin Allgaier to grab his fourth win of the season.
