A one-piece shotgun is configured to absorb impact energy when a front of the vehicle is impacted. The shotgun comprises an upper portion, a mid portion, and a lower portion, the upper portion having an end configured to connect to a hinge pillar; and a Z-trigger formed by two indentations and being located adjacent the upper portion end. The indentations of the Z-trigger are located on an outer side and an inner side of the shotgun to cause substantially lateral bending when sufficient force is applied to the shotgun.

1. A method for reducing pitch of a front portion of a vehicle upon front impact of the vehicle, the method comprising: using a Z-trigger located in an upper portion of a shotgun of the vehicle to cause substantially lateral bending of the shotgun into a Z-shape when sufficient force is applied to the shotgun during a front impact. 2. The method of claim 1, further comprising hydroforming the shotgun with the Z-trigger. 3. The method of claim 1, further comprising providing a second set of triggers located in an upper portion of the shotgun between the Z-trigger and a front of the vehicle. 4. The method of claim 3, wherein the second set of triggers is configured to bend before the Z-trigger. 5. The method of claim 4, wherein sequential bending of the Z-trigger and the second set of triggers occurs when sufficient force is applied to the shotgun, such that indentations closer to a front of the vehicle cause bending earlier than indentations closer to a rear of the vehicle. 6. A one-piece shotgun of a frame of a vehicle, the shotgun configured to absorb impact energy when a front of the vehicle is impacted, the shotgun having an upper portion with a rear end configured to connect to a hinge pillar, the shotgun comprising: a front crash zone comprising at least a first weakened area and a second weakened area on an upper portion of the shotgun, the second weakened area being located closer to the rear end of the shotgun than the first weakened area; anda Z-trigger configured to cause substantially lateral bending of the shotgun into a Z-shape, the Z-trigger comprising a third weakened area and a fourth weakened area on an upper portion of the shotgun, the fourth weakened area being located closer to the rear end of the shotgun than the third weakened area,wherein the first weakened area is configured to bend before the second weakened area, the second weakened area is configured to bend before the third weakened area, and the third weakened area is configured to bend before the fourth weakened area during an impact. 7. The one-piece shotgun of claim 6, wherein the weakened areas are located on inner or outer sides of the shotgun. 8. The one-piece shotgun of claim 6, wherein the first weakened is weaker than the second weakened area, the second weakened area is weaker than the third weakened area, and the third weakened area is weaker than the fourth weakened area. 9. The one-piece shotgun of claim 6, wherein the weakened areas comprise at least one of holes, beads, darts, scoring, a lessened shotgun height, and a lessened shotgun width. 10. The one-piece shotgun of claim 6, wherein the shotgun is hydroformed. 11. The one-piece shotgun of claim 10, wherein the weakened areas are created during hydroforming.
