Würth 400 presented by LIQUI MOLY

Texas Motor Speedway is a 1.5-mile quad-oval in Fort Worth that has been one of NASCAR's most-studied intermediate puzzles since opening in 1997. The 2017 reconfiguration narrowed the racing surface and added asymmetric banking (20 degrees in turns 1-2, 24 degrees in turns 3-4) that dramatically changed the racing character and put a premium on rear-grip setups that can rotate the car off the corner. Tire wear is significant here, and a high line gradually opens up as rubber lays down on the worn outside groove, creating the kind of two-groove racing that rewards drivers willing to hunt for grip across the width of the track. Recent Texas Cup races have often been decided as much in pit lane as on the track: stage-point strategy, tire compound choices, and pit cycle timing routinely shake the field, and the long frontstretch creates draft windows that can swing two or three positions on a single restart. The Würth 400 sits in the middle of the regular season as one of the truer reads on which intermediate cars have closed the gap to the front, and the 267-lap distance gives long-run patience time to matter while still leaving room for late strategy plays to decide the trophy.
