The 2017 Kobalt 400 was a Monster Energy NASCAR Cup Series race that was held on March 12, 2017, at Las Vegas Motor Speedway in Las Vegas. Contested over 267 laps on the 1.5 mi (2.4 km) asphalt intermediate speedway, it was the third race of the 2017 Monster Energy NASCAR Cup Series season.
Las Vegas Motor Speedway, located in Clark County, Nevada outside the Las Vegas city limits and about 15 miles northeast of the Las Vegas Strip, is a 1,200-acre (490 ha) complex of multiple tracks for motorsports racing. The complex is owned by Speedway Motorsports, Inc., which is headquartered in Charlotte, North Carolina.
Martin Truex, Jr. was the fastest in the first practice session with a time of 27.907 seconds and a speed of 193.500 mph (311.408 km/h).
Brad Keselowski scored the pole for the race with a time of 27.881 and a speed of 193.680 mph (311.698 km/h). When asked how he accomplished this despite missing his mark in Turns 1 and 2 on his pole lap, he said he didn't "know what the answer is. I'll have to look through a bunch of data, and the smart guys -- the engineers and crew chiefs -- will probably point some of that stuff out to me. But, yeah, every time I looked at the tracker, the cars that were fast in 1 and 2 weren't in 3 and 4, and we were the opposite. We were really good in 3 and 4… but we'll take it either way."
Chase Elliott was the fastest in the second practice session with a time of 28.197 seconds and a speed of 191.510 mph (308.205 km/h).
Martin Truex Jr. was the fastest in the final practice session with a time of 28.630 seconds and a speed of 188.613 mph (303.543 km/h).
Brad Keselowski led the field to the green flag at 3:48 p.m. He pulled away from Martin Truex Jr. in the opening laps, but Truex started reeling him back in around lap 12. The first caution of the race flew on lap 18 when Corey LaJoie slammed the wall in Turn 2. He went on to finish last. Truex exited pit road with the race lead.
