In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Lyriq are reminded to check the back seat if they opened the rear door before starting out. The R1S doesn’t offer a back seat reminder.
The Lyriq’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 R1S 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 Cadillac Lyriq achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Rivian R1S has not been tested.
Over 200 people are killed each year when backed over by motor vehicles. The Lyriq has standard Reverse Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The R1S doesn’t offer backup collision prevention brakes.
The Cadillac Lyriq comes with a standard HD Surround Vision and it also offers an optional rear camera washer to make backing always safe, regardless of road dirt or grime, while the Rivian R1S doesn’t offer a camera washer, requiring manual cleaning.
Both the Lyriq and R1S have rear cross-traffic warning, but the Lyriq has Rear Cross Traffic Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The R1S’ Rear Cross-Traffic Warning doesn’t automatically brake.
Both the Lyriq and the R1S 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, around view monitors, rear cross-path warning and available driver alert monitors.
