For enhanced safety, the front and rear seat shoulder belts of the Genesis G90 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The BMW 5 Series Sedan doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Genesis G90 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 BMW 5 Series Sedan doesn’t offer height-adjustable seat belts.
Both the G90 and 5 Series 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 5 Series 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 5 Series 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 5 Series Sedan doesn’t offer front seat center airbags.
The G90 has standard Anti-Whiplash Front Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Anti-Whiplash Front Head Restraints system moves the headrests forward to prevent neck and spine injuries. The 5 Series Sedan doesn’t offer a whiplash protection system.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the G90. But it costs extra on the 5 Series Sedan.
The G90 has a standard Surround View Monitor to allow the driver to see objects all around the vehicle on a screen. The 5 Series Sedan 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.
Both the G90 and 5 Series Sedan have rear cross-traffic warning, but the G90 has Rear Cross-Traffic Collision-Avoidance Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The 5 Series Sedan’s Cross Traffic Warning doesn’t automatically brake.
Both the G90 and the 5 Series Sedan have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, 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, rear cross-path warning and driver alert monitors.
The Genesis G90 weighs 445 to 1366 pounds more than the BMW 5 Series Sedan. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
The Genesis G90 has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2024 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned an “Acceptable” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The 5 Series Sedan has not yet been fully evaluated by the IIHS for 2024.
