For enhanced safety, the front seat shoulder belts of the Lexus ES are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Tesla Model S doesn’t offer height-adjustable seat belts.
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 Model S 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 Model S doesn’t offer backup collision prevention brakes.
The ES offers an optional Panoramic View Camera to allow the driver to see objects all around the vehicle on a screen. The Model S 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.
To help make backing out of a parking space safer, the ES’ standard Rear Cross-Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side and automatically engages the brakes to help avoid a collision. The Model S doesn’t offer a rear cross-path warning system.
The ES has standard Safety Connect®, which uses a global positioning satellite (GPS) receiver and a cellular system to help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Model S doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the ES and the Model S have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras and driver alert monitors.

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 Model S does not qualify as a “Top Safety Pick.”
