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 Escalade-V are reminded to check the back seat if they opened the rear door before starting out. The Cayenne doesn’t offer a back seat reminder.
The Escalade-V’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 Cayenne doesn’t offer a driver alert monitor.
Both the Escalade-V and the Cayenne have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, 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, rearview cameras and rear cross-path warning.
The Cadillac Escalade-V weighs 697 to 1841 pounds more than the Porsche Cayenne. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
