The XC40 Recharge’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The RZ doesn’t offer pre-crash pretensioners.
Both the XC40 Recharge and RZ have child safety locks to prevent children from opening the rear doors. The XC40 Recharge 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 RZ’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 XC40 Recharge 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 RZ doesn’t offer a whiplash protection system.
Both the XC40 Recharge and the RZ have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the XC40 Recharge the rating of “Top Safety Pick” for 2017, a rating granted to only 234 vehicles tested by the IIHS. The RZ has not been tested, yet.
