Kentucky Speedway is a 1.5-mile (2.4 km) tri-oval speedway in Sparta, Kentucky, which has hosted ARCA, NASCAR and Indy Racing League racing annually since it opened in 2000. The track is currently owned and operated by Speedway Motorsports, Inc. and Jerry Carroll, who, along with four other investors, owned Kentucky Speedway until 2008. The speedway has a grandstand capacity of 117,000. Construction of the speedway began in 1998 and was completed in mid-2000. The speedway has hosted the Camping World Truck Series, Nationwide Series, IndyCar Series, Indy Lights, and most recently, the Sprint Cup Series beginning in 2011.

The entry list for the Quaker State 400 was released on Monday, June 23, 2014, at 9:09 a.m. Eastern time. Only 42 cars entered the race which made this the first Sprint Cup Series race without a full field of 43 drivers, since the 2001 New Hampshire 300 at New Hampshire Motor Speedway. NASCAR's senior director of communications Kerry Tharp denied that there was any "magic" to a 43-car grid, and also noted how well the sport had been progressing with an improvement in competition. Hendrick Motorsports drivers Jimmie Johnson and Jeff Gordon backed up Tharp's words, with both drivers unconcerned about the lack of a full grid.[12] While the field expanded to 43 on June 27 after BK Racing entered Mike Bliss in the No. 93, J. J. Yeley and Xxxtreme Motorsport withdrew later in the day, citing "internal politics".[12]

Kyle Larson was the fastest in the first practice session with a lap time of 29.420 and a speed of 183.549 mph (295.393 km/h).

Brad Keselowski was the fastest in the final practice session with a lap time of 29.492 and a speed of 183.101 mph (294.672 km/h).

Brad Keselowski won the race from the pole position.

Prior to the start of the race, there was a downpour that soaked the track. This prompted NASCAR to schedule a competition caution at lap 30. The race was scheduled to start at 7:45 p.m. Eastern time but started three minutes earlier with Brad Keselowski leading the field to the green flag. Jeff Gordon slipped on the start and fell to eighth. Just ahead of the scheduled competition caution, Denny Hamlin hit the wall in turn three after a tire blowout, and caused the first caution of the race. Hamlin described his impact as "definitely a lot easier than some of the hits I've taken in the past", but was uninjured in the incident.[14] Keselowski led the field to the green on the restart on lap 35, starting a lengthy green-flag run, before the race's second caution on lap 77, caused by Kyle Larson hitting the wall in turn 1. Joey Logano took the lead from teammate Keselowski during the cycle of pit stops.

Logano led the field to the restart on lap 85, before Keselowski was able to retake the lead two laps later. Another lengthy green-flag run ensued, before debris forced the third caution of the race on lap 126. Prior to the caution, Matt Kenseth suffered a flat right-front tire, and had to pit from sixth position. Logano retook the lead during the pit cycle, while Jeff Gordon suffered a slow pit stop due to a malfunctioning air hose; he lost a total of 16 positions, dropping from 7th to 23rd. Logano and Keselowski swapped the lead positions once again, prior to the fourth caution, on lap 153, for a multi-car wreck on the backstretch involving Aric Almirola, Alex Bowman, Kasey Kahne and Jamie McMurray. Bowman locked up his brakes and tires, causing a large cloud of smoke that made it difficult for trailing cars to see what was in front of them. When the smoke cleared, Almirola swerved to his right to avoid Bowman, but in the process got into the left side of McMurray's car.[15]

The race restarted on lap 161 with Logano leading the field, but Keselowski was back in front a couple of laps later, holding the lead until the fifth caution on lap 176, which was brought out by David Stremme, who spun in turn 4. Logano took the lead on the restart on lap 182, but Keselowski repeated his feat of passing Logano within the first few laps of the restart. Aric Almirola brought out the sixth caution on lap 214 when he hit the wall in turn 1. Kyle Busch took the lead during the cycle; he was the only driver other than the Penske drivers to lead laps during the event, leading 31. Keselowski took the lead from Busch with 20 laps to go and took the checkered flag for the second time in 2014. Keselowski described his car as "awesome" and praised his team for doing a great job".[16] Busch was pleased at his upturn in performance, stating that his car was "a lot better than we've been all year long", but that it had "got so loose there at the end". He was still able to finish in second place, just over a second behind Keselowski.[17]
