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 Taycan doesn’t offer a back seat reminder.
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 and automatically apply the brakes to prevent a rear collision. The Taycan doesn’t offer backup collision prevention brakes.
The Lyriq has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the Taycan’s blind spot costs extra.
To help make backing out of a parking space safer, the Lyriq has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the Taycan.
Both the Lyriq and the Taycan have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front 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 and rearview cameras.
The Cadillac Lyriq weighs 411 to 1042 pounds more than the Porsche Taycan. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
