The Escalade IQ 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 ZDX doesn’t offer front seat center airbags.
To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the Escalade IQ. But it costs extra on the ZDX.
A passive infrared night vision system standard on the Escalade IQ Premium helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The ZDX doesn’t offer a night vision system.
The Escalade IQ’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 ZDX doesn’t offer a driver alert monitor.
Both the Escalade IQ and the ZDX 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, lane departure warning systems, blind spot warning systems, rearview cameras and rear cross-path warning.
The Cadillac Escalade IQ weighs 3068 to 3699 pounds more than the Acura ZDX. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
