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 Celestiq are reminded to check the back seat if they opened the rear door before starting out. The Polestar 2 doesn’t offer a back seat reminder.
The Cadillac Celestiq has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Polestar 2 doesn’t offer a front passenger side knee airbag.
Both the Celestiq and the Polestar 2 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, 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, around view monitors and rear cross-path warning.
The Cadillac Celestiq weighs 1286 to 1496 pounds more than the Polestar 2. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
