The Escalade-V’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Cayenne doesn’t offer pre-crash pretensioners.
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.
Both the Escalade-V and the Cayenne have standard driver and passenger frontal airbags, front side-impact 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 553 to 1729 pounds more than the Porsche Cayenne. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
