The GMC Acadia, redesigned for the 2017 model year, marked a significant shift to a more compact and lighter midsize SUV. This design evolution is crucial for understanding the safety performance of models like the 2018 Gmc Acadia. It’s important to note that this rating specifically applies to Acadia models from 2017 to 2023 and does not include the 2017 GMC Acadia Limited, which was a continuation of the older, larger design available only to fleet buyers.
The safety evaluations provided here are based on a moderate overlap frontal test conducted by General Motors on the GMC Acadia. These ratings are also applicable to the Cadillac XT6, a luxury midsize SUV introduced in 2020, highlighting a shared safety engineering foundation.
| Evaluation criteria | Rating |
|---|---|
| Overall evaluation | G |
| Structure and safety cage | G |
| Driver injury measures | |
| Head/neck | G |
| Chest | G |
| Leg/foot, left | G |
| Leg/foot, right | A |
| Driver restraints and dummy kinematics | G |
The table above summarizes the crash test performance of the 2018 GMC Acadia and similar models. The “Overall Evaluation” and “Structure and Safety Cage” both received the highest rating of “Good” (G). For “Driver injury measures,” assessments for “Head/Neck,” “Chest,” and “Leg/Foot, Left” also earned a “Good” rating. The “Leg/Foot, Right” measure received an “Acceptable” (A) rating, while “Driver restraints and dummy kinematics” were rated as “Good.”

This table provides detailed measurements of occupant compartment intrusion during the crash test. These measurements are crucial for understanding the structural integrity of the 2018 GMC Acadia in a frontal collision. For instance, footwell intrusion measurements indicate the extent to which the footwell area was compromised. Similarly, instrument panel and steering column movement measurements reveal how much these components were displaced during the impact. Lower intrusion values generally indicate better structural performance, contributing to occupant safety.

The final table outlines specific driver injury measures recorded during the test. These metrics are vital for assessing the effectiveness of the 2018 GMC Acadia’s safety systems in protecting the driver. Measurements like Head Injury Criterion (HIC), neck tension, chest compression, femur force, and tibia index are used to evaluate the potential for injuries to different body regions. Lower values in these measurements generally indicate a lower risk of injury. The data suggests good protection for the driver in a moderate overlap frontal crash scenario for the 2018 GMC Acadia and similar models within the 2017-2023 range.
