The 2014 STP 500 was a NASCAR Sprint Cup Series stock car race that was held on March 30, 2014, at Martinsville Speedway in Ridgeway, Virginia. Contested over 500 laps on the oval, it was the sixth race of the 2014 NASCAR Sprint Cup Series. Kurt Busch won the race, his first win with Stewart–Haas Racing, breaking an 83-race winless streak. Jimmie Johnson finished second, while Dale Earnhardt Jr., Joey Logano, and Marcos Ambrose rounded out the top five. The top rookies of the race were Austin Dillon (15th), Justin Allgaier (23rd), and Kyle Larson (27th).

Previous week's race On the final lap of the Auto Club 400, Kyle Busch passed his brother Kurt Busch and held off a hard charging rookie Kyle Larson to win the race. "Holy cow, what do you expect when you have a green-white-checkered finish and everyone comes down pit road to put on four tires," Busch said. "That's a Days of Thunder thing right there. What do you mean, there's two laps to go, everybody is to pit, Cole. I came off the fourth turn in disbelief that we won this thing, because we were mediocre all day. It was really weird for us, not a race that we're typically used to. But now there's a load off your shoulders that you can go out the rest of the season and race the way you want to." After winning his first Nationwide Series race the previous day, Larson stated that it had "been a really good weekend" and that he had been battling "probably a 12th place car for most of the day".

Race First half Start The race began at 1:13 p.m. Eastern time with Kyle Busch leading the field to the green flag from the outside line on the initial start. With the tight confines of Martinsville, it did not take long for the first caution of the race to wave. It flew on lap 2 after Parker Kligerman hit the back of Martin Truex Jr. and spun out in turn 3. A number of cars towards the back were on pit road for damage sustained in a classic Martinsville accordion effect. The race restarted on lap 11, before Matt Kenseth took the lead on lap 17. Jimmie Johnson took the lead on lap 21 and held the lead to the competition caution on lap 41 due to overnight rain. Travis Kvapil stayed out to lead a lap before giving the lead back to Johnson. Brad Keselowski was exiting pit road when he collided with Kasey Kahne who was entering. The bulk of the damage came when Kurt Busch clipped the right side of Keselowski's car. He was forced to take his car to the garage. Keselowski felt that Busch "just accelerated and drove through us, absolutely drove through us" and that he was "tired of his recklessness".

Tempers flaring The race restarted on lap 48, with Kenseth retaking the lead on lap 56. Kyle Busch took back the lead on lap 59, before the lead cycled to Joey Logano on lap 65, and back to Johnson on lap 82. Keselowski returned to the track for a payback move at Kurt Busch; he gave out the middle finger until Kurt Busch bumped him out of the way. Keselowski's car ultimately left a tire mark on the left side of Kurt Busch's car. After the race, Kurt Busch stated that he had "steered right to go around Brad and he clobbers our left-side door" and later described Keselowski's move as "punk-ass" and that he "will get what he gets back when I decide to give it back". The two drivers battled for 17 laps in total. Ricky Stenhouse Jr. wheel-hopped the curb in turn 1 trying to avoid ramming Kurt Busch and scraped the wall, which brought out the third caution of the race on lap 103. Matt Kenseth beat Jimmie Johnson off pit road to take the lead for the restart, on lap 110.

Cautions breed cautions Logano took back the lead on lap 111, before the fourth caution of the race flew on lap 114 after Kvapil clipped Michael Annett going into turn 3, with the incident also involving David Gilliland. From the restart at lap 120, Logano maintained the lead until lap 133, when Johnson returned to the head of the race. Greg Biffle became the race's next leader on lap 155, and held the lead until the fifth caution of the race flew on lap 170 after Casey Mears got tapped by Gilliland in turn 1 and sent him spinning. Marcos Ambrose beat Biffle off pit road to take the lead for the restart on lap 179. Ambrose led until on lap 195 when Kenseth passed him. The sixth caution of the race flew on lap 200 after Dale Earnhardt Jr. tapped Jamie McMurray in turn 2 and sent his car into the wall. Kenseth led the field to the restart on lap 208, before Johnson returned to the lead on lap 213.

Second half Halfway

The seventh caution of the race flew on lap 219 after Alex Bowman got hit in the rear by Gilliland and rear-ended the wall in turn 4. Earnhardt Jr. stayed out on track while others pitted for tires, and thus took the lead for the restart, on lap 226. A short green-flag run followed before debris in turn 1 brought out the eighth caution of the race on lap 231. Kevin Harvick's run of mechanical mishaps continued when he was forced to pit because of a broken rear-end chain. Earnhardt Jr. still led the field for the restart on lap 238, before Kurt Busch took the lead on lap 243. Johnson returned to the front on lap 245, before the ninth caution of the race flew at the halfway mark, after Ryan Truex was sent spinning into the turn 4 wall. Harvick stayed out to lead a lap before pitting and the lead cycled back to Kenseth for the restart, on lap 258.
