Both the Celestiq and EQE Sedan have child safety locks to prevent children from opening the rear doors. The Celestiq has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The EQE Sedan’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
The Cadillac Celestiq has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags help 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 EQE Sedan doesn’t offer a front passenger side knee airbag.
To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the Celestiq. But it costs extra on the EQE Sedan.
A passive infrared night vision system optional on the Celestiq helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The EQE Sedan doesn’t offer a night vision system.
The Cadillac Celestiq’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Mercedes EQE Sedan does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.
Both the Celestiq and the EQE Sedan 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, around view monitors, rear cross-path warning and driver alert monitors.
The Cadillac Celestiq weighs 466 to 720 pounds more than the Mercedes EQE Sedan. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
