Just to recap some of the changes announced Oct. 2022
_______________________________________________________________________________________________________________________________________________
The changes to the Next Gen car should create a better crumple zone behind the driver so that they absorb less force in rear impacts, which has been the case in several crashes in 2022 due to the rigidness of the Next Gen car's current rear bumper structure and supports. The changes are as follows:
- New rear bumper struts with a new material thickness of 0.080 inches, which will allow them to crumple better.
- Longitudinal bars in the upper part of the rear clip are being removed, while the lower rails are being changed from relatively straight to angled compound mitered tubes.
- Outer diagonal tubes near the top of the center section of the chassis will now feature a trigger on the inboard side as opposed to two existing inner diagonal support bars. Outer diagonal tubes on the bottom of the chassis are being replaced by 1.75 inch diameter tubes with an 0.65 inch wall and triggers. Inner diagonal tubes at the bottom of the chassis will be reduced to one inch in diameter with a 0.065 inch wall without triggers.
