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 R1S doesn’t offer pre-crash pretensioners.
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. Rivian doesn’t offer the convenience and security of a built-in child booster seat in the R1S. 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.
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 R1S doesn’t offer a whiplash protection system.
The XC60 has standard Automatic Braking After Collision, which automatically apply the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The R1S 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.
Both the XC60 and the R1S have standard driver and passenger frontal airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors, available all wheel drive and front parking sensors.
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 Pick Plus” for 2021, a rating granted to only 76 vehicles tested by the IIHS. The R1S has not been tested, yet.
