The G90’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Quattroporte doesn’t offer pre-crash pretensioners.
Both the G90 and Quattroporte 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 Quattroporte’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 Quattroporte 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 Quattroporte doesn’t offer front seat center airbags.
Over 200 people are killed each year when backed over by motor vehicles. The G90 has a standard Parking Collision-Avoidance Assist-Reverse that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Quattroporte doesn’t offer backup collision prevention brakes.
Both the G90 and Quattroporte 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 Quattroporte’s Rear Cross Path doesn’t automatically brake.
The G90’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Quattroporte doesn’t offer a driver alert monitor.
Both the G90 and the Quattroporte 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, all wheel drive, 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 and rear cross-path warning.
The Genesis G90 weighs 595 to 916 pounds more than the Maserati Quattroporte. 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 Quattroporte has not yet been evaluated by the IIHS for 2024.
