For enhanced safety, the front and rear seat shoulder belts of the Lexus ES have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Chrysler 300 doesn’t offer pretensioners for its rear seat belts.
The Lexus ES 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 300 doesn’t offer a front passenger side knee airbag.
The ES has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The 300 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
Over 200 people are killed each year when backed over by motor vehicles. The ES offers optional Intuitive Parking Assist with Auto Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The 300 doesn’t offer backup collision prevention brakes.
The ES’ 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 300.
The ES offers an optional Panoramic View Camera to allow the driver to see objects all around the vehicle on a screen. The 300 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
The ES has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. Only the 300 S/Touring L offers a blind spot warning system.
To help make backing out of a parking space safer, the ES has standard Rear Cross-Traffic Alert to warn the driver of approaching traffic and automatically engage the brakes to help avoid a collision. Only the 300 S/Touring L offers Rear Cross Path Detection and the 300’s Rear Cross Path Detection does not include automatic braking.
The ES’ driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The 300 doesn’t offer a driver alert monitor.
Both the ES and the 300 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Lexus ES is safer than the Chrysler 300:

A significantly tougher test than their original offset frontal crash test, the Insurance Institute for Highway Safety does 40 MPH small overlap frontal offset crash tests. In this test, where only 25% of the total width of the vehicle is struck, results indicate that the Lexus ES is safer than the 300:

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, and daytime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the ES the rating of “Top Safety Pick” for 2023, a rating granted to only 53 vehicles tested by the IIHS. The 300 is not a “Top Safety Pick.”
