The XC60’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.
Both the XC60 and Cayenne have child safety locks to prevent children from opening the rear doors. The XC60 Plus/Ultimate/Polestar 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 Cayenne’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.
The Volvo XC60 offers optional built in child booster seats. They’re more crash worthy than an added child seat because of their direct attachment to the seat. Porsche doesn’t offer the convenience and security of a built-in child booster seat in the Cayenne. Their owners must carry a heavy booster seat in and out of the vehicle; XC60 owners can just fold their built-in child seat up or down.
Using vehicle speed sensors and seat sensors, smart airbags in the XC60 deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The XC60’s side airbags will shut off if a child is leaning against the door. The Cayenne’s side airbags don’t have smart features and will always deploy full force.
The XC60 has a standard Whiplash Protection System (WHIPS), which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the WHIPS allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. At the same time the pretensioning seatbelts fire, removing slack from the belts. The Cayenne doesn’t offer a whiplash protection system.
Over 200 people are killed each year when backed over by motor vehicles. The XC60 has standard CTA Auto Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Cayenne doesn’t offer backup collision prevention brakes.
The XC60’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the Cayenne.
The XC60 has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the Cayenne’s blind spot costs extra.
To help make backing out of a parking space safer, the XC60’s standard Cross Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side and Braking Intervention automatically engages the brakes to help avoid a collision. The Cayenne doesn’t offer a rear cross-path warning system.
The XC60’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 XC60 and the Cayenne have standard driver and passenger frontal airbags, front side-impact airbags, driver 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, post-collision automatic braking systems, daytime running lights, rearview cameras and available around view monitors.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the XC60 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 128 vehicles tested by the IIHS. The Cayenne has not been tested, yet.
