The X3’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.
The X3 has standard Active Head Restraints, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Head Restraints system moves the headrests forward to prevent neck and spine injuries. The Murano doesn’t offer a whiplash protection system.
In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the BMW X3 achieved a “Good” rating - the highest possible - in forward collision warning and automatic braking systems, outperforming the Nissan Murano which scored only an “Acceptable” in these critical safety features.
The X3 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.
The BMW X3’s optional Surround View offers available integrated front and rear camera washers, ensuring clear, all-weather visibility without the need for manual cleaning. In contrast, the Nissan Murano lacks camera washers, requiring you to manually clean the cameras for optimal performance.
Both the X3 and Murano have rear cross-traffic warning, but the X3 has Cross Traffic Warning with braking function (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 X3 and the Murano have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, all-wheel drive, 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 around view monitors.
