The 2016 Cadillac CT6 is an all new sedan with advanced lightweight materials used in its body structure. This consists of a combination of 13 different materials, primarily aluminum and high-strength steels.  What caught my attention was the bottom of the A-pillar and the rear part of the front wheel well.  Rescuers are taught to thoroughly cut this area during a dash lift.  With the size of the base of the A-pillar and the UHSS steel used in the wheel well, rescuers may need to use a hybrid technique.

Take note of the size of the base of the A-pillar and the aluminium cast fender reinforcement.  If the photo below, you can see the UHSS and all the reinforcements in the wheel well.  During a dash lift, the rescuer with the cutters will want to remain in this area to nobble additional material toward the inside of the wheel well.

At the NACE conference, Detroit Firefighters from Squad 2 are using a hybrid technique that use the ram as part of a dash lift.  The ram is used to capture the current position of the dash and provide support so the dash cannot drop onto the patient.  With the body structure features posted above in the 2016 Cadillac CT6, the dash may need to be supported during the relief cuts into the wheel well.
