The X5’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Murano doesn’t offer pre-crash pretensioners.
With its standard Active Pedestrian Protection, the BMW X5 is better at preventing collisions with pedestrians than the Nissan Murano, according to the Insurance Institute for Highway Safety:

The X5 has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Murano 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.
When descending a steep, off-road slope, the X5’s standard Hill Descent Control allows you to creep down safely. The Murano doesn’t offer Hill Descent Control.
Both the X5 and Murano have rear cross-traffic warning, but the X5 has Cross Traffic Warning with Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The Murano’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the X5 and the Murano have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, 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, driver alert monitors and available all wheel drive.
The BMW X5 weighs 754 to 1681 pounds more than the Nissan Murano. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
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 BMW X5 is much safer than the Murano:

The BMW X5 achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The Murano is not a “Top Safety Pick” for 2024.
