Both the G90 and E-Class Sedan have child safety locks to prevent children from opening the rear doors. The G90 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 E-Class 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 G90 are reminded to check the back seat when a sensor determines the back seat is occupied. The E-Class Sedan doesn’t offer a back seat reminder.
The G90 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The E-Class Sedan doesn’t offer front seat center airbags.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the G90. But it costs extra on the E-Class Sedan.
The G90’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the E-Class Sedan.
To help make backing out of a parking space safer, the G90 has standard Rear Cross-Traffic Collision-Avoidance Assist and automatically engage the brakes. Mercedes charges extra for rear cross-path warning on the E-Class Sedan.
Both the G90 and the E-Class 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, blind spot warning systems, rearview cameras and driver alert monitors.
The Genesis G90 weighs 639 to 1375 pounds more than the Mercedes E-Class Sedan. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the G90 its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 29 vehicles tested by the IIHS. The E-Class Sedan has not been fully tested, yet.
