The four-inch curbing at Turn 16 is no more, just hours before the start of Sunday's NASCAR Cup Series elimination race at Charlotte. The corner apex, which was extended before the race weekend, created a narrower final corner.
Commonly called 'turtles' or 'sausage kerbs' elsewhere in the world, drivers were aggressively running over the top of the curbs during practice in qualifying, and later complained about how violent the hits were. For example, Martin Truex Jr. compared it to getting a concussion.
