Important: Frontal crash test ratings should be compared only among vehicles of similar weight.
The 2012 Acura TSX Sport Wagon is a twin of the tested vehicle.
The Acura TSX was redesigned for the 2009 model year. The small overlap front test ratings also apply to the station wagon version of the TSX, known as the TSX Sport Wagon, beginning with 2011 models.
Two tests of the TSX were conducted because the onboard (car interior) cameras failed during the first test. Also in the first test, the driver side curtain and side thorax airbags deployed, but they did not in the second test. Honda subsequently provided data showing that the side airbags are close to their deployment threshold under the small overlap test conditions. The restraints and dummy kinematics rating is based on the second test. Injury and structural ratings are based on both tests.
The driver space was not maintained well. The lower part of the door hinge pillar was pushed in toward the driver 23 cm, while the instrument panel intruded as much as 17 cm.
Measures from the dummies in the two tests, taken together, indicate that injuries to the left lower leg would be likely in a crash of this severity. The risk of significant injuries to other body regions is low.
Restraints and dummy kinematics
In the second test, the dummy’s head contacted the frontal airbag but slid off the left side, leaving the head vulnerable to contact with forward side structure. The side curtain airbag did not deploy, also leaving the dummy’s head vulnerable to contact with side structure and outside objects.
