The Optiq’s standard pretensioning seatbelts also sense rear collisions and remove slack from the seatbelts to help protect the occupants from whiplash and other injuries. The Ariya doesn’t offer a whiplash protection system.
To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the Optiq. But it costs extra on the Ariya.
The Cadillac Optiq’s rear backup camera has a standard washer for maintaining a clear view under various conditions. In contrast, the Nissan Ariya does not offer a rear camera washer, meaning its effectiveness relies on manual cleaning by the user when necessary.
Both the Optiq and Ariya have Rear Cross Traffic Alert, but the Optiq has Rear Cross Traffic Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The Ariya’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the Optiq and the Ariya have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, front seat center airbag, 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.
