Important: Frontal crash test ratings should be compared only among vehicles of similar weight.

The Acura RL was redesigned for the 2014 model year after a one-year absence from the market and renamed the RLX.

Structure

The driver space was maintained well, with maximum intrusion of the lower interior of 5 cm and maximum intrusion of the upper interior of 3 cm.

Injury measures

Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Restraints and dummy kinematics

The dummy’s movement was well controlled. The dummy’s head loaded the frontal airbag, which stayed in front of the dummy until rebound. The side curtain airbag deployed and had sufficient forward coverage to protect the head from contact with side structure and outside objects. The side torso airbag also deployed.

Important: Frontal crash test ratings should be compared only among vehicles of similar weight.

The Acura RL was redesigned for the 2014 model year after a one-year absence from the market and renamed the RLX. Moderate overlap frontal ratings are assigned by the Institute based on a test conducted by Honda as part of frontal crash test verification.

Injury measures

Measures taken from the head, neck, and chest indicate low risk of injuries to these body regions in a crash of this severity. Forces on the right tibia indicate that lower leg injuries would be possible.

Restraints and dummy kinematics

Dummy movement was well controlled. The driver side curtain airbag deployed during the crash. After the dummy moved forward into the frontal airbag, it rebounded into the seat without its head coming close to any stiff structure that could cause injury.

Side crash test ratings can be compared across vehicle categories.

The Acura RL was redesigned for the 2014 model year after a one-year absence from the market and renamed the RLX. Side ratings are assigned by the Institute based on a test conducted by Honda as part of side crash test verification.

Injury measures

Driver — Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Passenger — Measures taken from the dummy indicate a low risk of any significant injuries in a crash of this severity.

Head protection

Driver — The dummy’s head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.

Passenger — The dummy’s head was protected from being hit by any hard structures, including the intruding barrier, by a side curtain airbag that deployed from the roof.

Roof strength test ratings can be compared across vehicle categories.

In the test, the strength of the roof is determined by pushing a metal plate against one side of it at a slow but constant speed. The force applied relative to the vehicle's weight is known as the strength-to-weight ratio. This graph shows how the ratio varied as the test of this vehicle progressed. The peak strength-to-weight ratio recorded at any time before the roof is crushed 5 inches is the key measurement of roof strength.

A good rating requires a strength-to-weight ratio of at least 4. In other words, the roof must withstand a force of at least 4 times the vehicle's weight before the plate crushes the roof by 5 inches. For an acceptable rating, the minimum required strength-to-weight ratio is 3.25. For a marginal rating, it is 2.5. Anything lower than that is poor.

The low beams created some glare.

High 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 curve and inadequate on both left curves.
