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 RX doesn’t offer pre-crash pretensioners.
Both the XC60 and RX 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 RX’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. Lexus doesn’t offer the convenience and security of a built-in child booster seat in the RX. 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 RX’s side airbags don’t have smart features and will always deploy full force.
The XC60 has standard Post-impact braking, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The RX doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
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 and automatically apply the brakes to prevent a rear collision. The RX doesn’t offer backup collision prevention brakes.
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 RX doesn’t offer a driver alert monitor.
Both the XC60 and the RX have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, 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, rear cross-path warning, available all wheel drive and 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 112 vehicles tested by the IIHS. The RX has not been tested, yet.
