The Lexus RX has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The E-Class All-Terrain Wagon doesn’t offer a front passenger side knee airbag.
The RX has standard Active Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Headrests system moves the headrests forward to prevent neck and spine injuries. The E-Class All-Terrain Wagon doesn’t offer a whiplash protection system.
Over 200 people are killed each year when backed over by motor vehicles. The RX offers optional Auto Brake that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The E-Class All-Terrain Wagon doesn’t offer backup collision prevention brakes.
The RX’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the E-Class All-Terrain Wagon.
To help make backing out of a parking space safer, the RX has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the E-Class All-Terrain Wagon.
Both the RX and the E-Class All-Terrain Wagon have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, blind spot warning systems, rearview cameras, driver alert monitors, available all wheel drive and around view monitors.
The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Lexus RX is safer than the Mercedes E-Class All-Terrain Wagon:
