What performance is being tested by opening and closing the doors, frunk, and trunk of the YU7 GT on an articulation ramp?
Opening and closing the doors, frunk, and trunk of the YU7 GT on an articulation ramp is primarily to intuitively demonstrate the body's torsional rigidity. The armored cage body of the YU7 GT achieves a torsional rigidity of 47,610 N·m/deg, representing a high standard among SUV models.
Ultra-high torsional rigidity can be simply understood as the body being hard and sturdy enough. Therefore, handling feedback is more direct, linear, and controllable. The entire vehicle feels tight and integrated when driven, significantly improving tracking and laying a solid foundation for precise driving control and a higher handling limit.
If the torsional rigidity is insufficient, it may be impossible to smoothly open and close the doors, frunk lid, and trunk lid under articulation conditions. During continuous cornering on mountain roads or emergency obstacle avoidance, the vehicle's handling may be poor, compromising the driver's sense of safety and confidence.
At the same time, high torsional rigidity brings better NVH performance. When driving on rough roads, the body does not feel loose, and the body and interior components are less prone to abnormal noises and resonance. Not only is it fast and stable, but the driving texture is also highly premium. We highly recommend that everyone pay special attention to this during a test drive.
