The CX-70 Premium has a standard Secondary Collision Reduction System, 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.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the CX-70. But it costs extra on the Murano.
Both the CX-70 and Murano have Rear Cross Traffic Alert, but the CX-70 has Rear Cross Traffic 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 CX-70 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, height adjustable front shoulder belts, 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 around view monitors.
The Mazda CX-70 weighs 425 to 1005 pounds more than the Nissan Murano. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
