Safety features are well represented in the 2010 Lexus GS sedans. Standard features include front side bags, side curtain bags, and dual front knee airbags; Lexus’ more sophisticated VDIM stability control system and anti-lock brakes are also included across the line. Among the available electronic aids that might also help improve safety is the Pre-Collision System (PCS) included with the optional laser cruise control, which prepares safety systems for an anticipated collision. The Variable Gear Ratio Steering is both a safety feature and convenience—bringing quick response at low speeds or when it's needed, as well as stability at high velocity.
Along with a full complement of airbags, reports Cars.com, the Lexus GS's "optional pre-collision system incorporates active braking, which can trigger the brakes automatically under certain conditions...[an] advanced stability system anticipates instability or skidding before it occurs, monitors actual versus intended action, and helps correct problems using a mix of braking, throttle and steering control." Additional options include "run-flat tires [and] Lexus Link communications."
Cars.com points out for the Lexus GS 450h, "Adaptive cruise control can sense impending collisions and alert the driver," and "an adaptive front lighting system swivels the headlights several degrees during turns to better illuminate corners.”
Overall, crash-test safety is good but not quite perfect; federal results aren’t available, but in insurance industry-supported IIHS tests, the GS earns top "good" ratings in both frontal and side impacts, with a "marginal" rating in the seat-based rear-impact test.
"All-around visibility is good despite moderately shallow side and rear windows," due to the fact that 2010 Lexus GS seats are "set fairly high," says ConsumerGuide.
