Lexus has upgraded the safety offerings in the GS lineup significantly this year, but because it's so new, neither crash-test agency has yet put one on the sled.
Since both the car and the tests themselves have changed so radically, there's not much relevance in the previous GS' good crash performance. And while the National Highway Traffic Safety Administration (NHTSA) hasn't yet tested the GS, it's already earned Top Safety Pick status from the Insurance Institute for Highway Safety (IIHS), with top 'good' results for frontal, side, and rear impact tests, along with the new roof strength test.
The new GS also gets a lot more progressive about the way it tries to prevent accidents. The airbag count goes up to ten, with dual front and side airbags joined by curtain and rear-seat side airbags as well as front knee airbags. Active headrests are standard, and so are a rearview camera and parking sensors--and Bluetooth, which we consider a safety device.
New safety technology makes its way into the GS 350 in option packages. The GS' standard cruise control can be upgraded to active cruise control with a pre-collision warning system and braking intervention. A head-up display and night vision are offered, as are blind-spot monitors. Finally, a new lane-departure warning system works with a lane-keeping system to gently steer the GS back into its lane if the car's sensors detect a drift out of its proper driving lane.
