Both the i7 and EQE Sedan have child safety locks to prevent children from opening the rear doors. The i7 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.
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 i7 are reminded to check the back seat if they opened the rear door before starting out. The EQE Sedan doesn’t offer a back seat reminder.
The BMW i7 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 EQE Sedan doesn’t offer a front passenger side knee airbag.
Both the i7 and the EQE Sedan have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
The BMW i7 weighs 493 to 1021 pounds more than the Mercedes EQE Sedan. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
