Small overlap front: driver-side

Rating applies to 2017-20 models

Tested vehicle: 2017 Acura TLX 2.4L 4-door

The Acura TLX was introduced in the 2015 model year as a replacement for the discontinued Acura TL and TSX models. Beginning with 2017 models, the front door hinge pillar was reinforced to limit intrusion of the front wheel to improve occupant protection in small overlap frontal crashes.

Driver restraints and dummy kinematics
The dummy’s head contacted the frontal airbag but rolled to the left because the seat belt allowed excessive forward excursion of the head and torso. The side curtain airbag deployed and has sufficient forward coverage to protect the head from contact with side structure and outside objects. The side torso airbag also deployed.

Action shot taken during the small overlap frontal crash test.

The dummy's position in relation to the door frame, steering wheel, and instrument panel after the crash test indicates that the driver's survival space was maintained very well.

The dummy's head contacted the frontal airbag but rolled partway around the left side, allowing the head to move toward the gap in coverage between the frontal and side curtain airbags.

Although intrusion into the driver's space was minimal, forces on the dummy's legs were high enough to indicate a significant risk of injury to the left lower leg and a moderate risk to the left foot and right lower leg.

Moderate overlap front

Rating applies to 2015-20 models

Tested vehicle: 2015 Acura TLX 3.5L Technology 4-door

The Acura TLX was introduced in the 2015 model year. It is a replacement for the discontinued Acura TL and TSX models. Moderate overlap frontal ratings are assigned by the Institute based on a test conducted by Honda as part of frontal crash test verification.

Low beams
On the straightaway, visibility was good on the right side of the road and fair on the left side. On curves, visibility was good on the gradual right curve, fair on the sharp right and sharp left curves, and inadequate on the gradual left curve.

The low beams never exceeded glare limits.

High beams
On the straightaway, visibility was good on the right side of the road and inadequate on the left side. On curves, visibility was fair on both right curves and inadequate on both left curves.

High-beam assist compensates for some limitations of this vehicle's low beams on the straightaway and all 4 curves.
