To determine what changes needed to be made, NASCAR ran through a series of crash tests that included launching a Next Gen test car at another. We still do have bent door bars but minimal intrusion and much better performance.” We reconstructed that crash at a test facility and we’re pleased with the performance where we’re hanging on to everything. “The right-side door bars of the centre section is getting a steel plate welded to it and really what it does it’s strengthening the right-side door bars against intrusion for crashes like we saw at Talladega with the #5 and #41. We’ve also added slots to this ballast container as well as some holes, and it’s all an effort to increase the amount of displacement we’re getting out of the car and to reduce the accelerations that the driver is experiencing. “We have slots on both sides, we have deleted some cross members between the upright mounts and we’ve treated some of the areas down low that are some of the first to contact the wall on the front clip. “We’ve taken a lot of the steel structural members and removed material from key elements to make this structure less stiff,” commented NASCAR vice president of safety engineering Dr. The opposite side has two plate gussets and the driver’s side of the cage is also supported by additional tubing. 060 inches thick has been added and is now required for all cars. On the right-side door, a steel plate approximately. The front clip and strut of the car have been softened through means like adding slots and holes to the front ballast box, which must remain empty at all times. Atlanta is a 1.5-mile track but its current configuration promotes superspeedway-style racing akin to what is seen at Talladega. In response to such a destructive wreck, NASCAR announced Thursday the introduction of various safety changes to the Next Gen car that will first be rolled out at Atlanta Motor Speedway on 9 July. At the NASCAR Cup Series‘ Talladega Superspeedway round in April, Kyle Larson‘s day ended in wild fashion when his car slid up the track amid a multi-driver crash and was T-boned by Ryan Preece at such high speed that his door bar broke off its original location while the passenger’s side door was partially torn off.
