The EQS SUV’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Model X doesn’t offer pre-crash pretensioners.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the EQS SUV are reminded to check the back seat if they opened the rear door before starting out. The Model X doesn’t offer a back seat reminder.
The EQS SUV’s standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The Model X doesn’t offer a whiplash protection system.
The EQS SUV has a standard Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Model X 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 EQS SUV has a standard Maneuvering Brake Function that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Model X doesn’t offer backup collision prevention brakes.
When descending a steep, off-road slope, the EQS SUV 4MATIC’s standard Downhill Speed Regulation allows you to creep down safely. The Model X doesn’t offer Downhill Speed Regulation.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The EQS SUV has Car-to-X Communication, a system that seamlessly communicates important warnings to the driver about impending danger, if they're available. The Model X doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
The EQS SUV has a standard Surround View System to allow the driver to see objects all around the vehicle on a screen. The Model X 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 EQS SUV’s standard Rear Cross-Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side and Active Brake Assist automatically engages the brakes to help avoid a collision. The Model X doesn’t offer a rear cross-path warning system.
The EQS SUV has standard Mercedes-Benz Emergency Call, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Model X 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 EQS SUV and the Model X 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, lane departure warning systems, blind spot warning systems, rearview cameras and driver alert monitors.
The Mercedes EQS SUV weighs 673 to 1142 pounds more than the Tesla Model X. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
