Both the Grecale and XT4 have child safety locks to prevent children from opening the rear doors. The Grecale 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 XT4’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.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Grecale. But it costs extra on the XT4.
The Grecale’s optional 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 XT4 doesn’t offer a driver alert monitor.
Both the Grecale and the XT4 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front 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, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.
The Maserati Grecale weighs 410 to 809 pounds more than the Cadillac XT4. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
