The LS’ pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Model S doesn’t offer pre-crash pretensioners.
For enhanced safety, the front seat shoulder belts of the Lexus LS 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 LS has standard Secondary Collision Brake, which automatically apply 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 LS has a standard Parking Support Brake 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 LS has a standard 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.
The Lexus LS’ rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Tesla Model S does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.
The LS 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 LS 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, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and driver alert monitors.
