To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the Vistiq. But it costs extra on the RZ.
A passive infrared night vision system standard on the Vistiq Premium Luxury/Platinum helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The RZ doesn’t offer a night vision system.
To help make backing out of a parking space safer, the Vistiq has standard Rear Cross Traffic Alert with Rear Cross Traffic Braking, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Only the RZ Premium/Luxury offers Parking Support Brake.
Both the Vistiq and the RZ 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 and driver alert monitors.
The Cadillac Vistiq weighs 1707 to 2049 pounds more than the Lexus RZ. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
