The 2013 Lexus GS was evaluated by the IIHS (Insurance Institute for Highway Safety) and the vehicle received a “Good” overall rating, the highest one available. The actual tests were conducted by Toyota as part of a crash test verification, with the Institute offering the ratings based on these.
During the frontal impact test, a moderate overlap one, the dummy movements was kept under control, but its head hit the roof rail during the rebound phase. This didn’t affect the rating as the acceleration resulting from the impact was low.
The side impact test results showed a low risk of significant injuries for the driver and the same was true for the rear passenger, with one exception. We’re referring to the head protection, as the dummy’s head went past the side curtain airbag and was hit by the window sill. No high head injury measures resulted from this, but the car received an “Adequate” head protection rating for the rear passenger. Nevertheless, the overall rating for the side impact is “Good”.
The tests also included a roof strength one, where a metal plate is pressed against one corner of the car’s roof. The GS also received a “Good” rating here, with its strength-to-weight ration being situated close to the class average.
To achieve the aforementioned ratings, engineers fitted the GS with an array of safety features and we’ll start with the ones you don’t want to use. The car’s passive safety systems include 10 airbags, two frontal ones, individual seat-mounted ones for front and rear occupants, side curtain airbags, as well as knee airbags for the driver and front passenger.
In addition to that, the front seats use a Whiplash Injury Lessening (WIL) feature that limits space between the headrest and the head of the occupant, aiming to reduce the whiplash injuries.
The active safety front is led by multiple optional features, starting with the per-collision one. This relies on the dynamic cruise control’s radar to monitor the road ahead and warns the driver in the even of an imminent collision. It also uses an infrared camera that monitors the driver’s eyes. If the system detects an imminent collision and the driver doesn’t seem to be looking ahead, it will send an early warning. Should the driver not respond, the system can apply light braking pressure up to two seconds before the crash.
The list of available active safety features includes Lane Departure Warning and Lane Keep Assist, which can use light steering inputs to keep the car in its lane, a Head Up Display, a Night Vision System, as well as a Blind Spot Monitor.Continue reading
