The Acura RDX has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The XC40 doesn’t offer a front passenger side knee airbag.
Both the RDX and the XC40 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, plastic fuel tanks, 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.
The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Acura RDX is safer than the Volvo XC40:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.
Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Acura RDX is safer than the XC40:

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the RDX its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 29 vehicles tested by the IIHS. The XC40 has not been fully tested, yet.
