The Crown has standard Whiplash Injury Lessening Seats, which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Injury Lessening Seats system allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The Accord doesn’t offer a whiplash protection system.
The Crown has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Accord doesn’t offer all-wheel drive.
The Crown (except XLE) offers an optional Bird’s Eye View Camera to allow the driver to see objects all around the vehicle on a screen. The Accord only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
To help make backing out of a parking space safer, the Crown has standard rear cross-path warning, helping the driver avoid collisions. Only the Accord EX/Sport/EX-L/Touring offers Cross Traffic Monitor.
Both the Crown and the Accord have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, 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 Toyota Crown weighs 718 to 1067 pounds more than the Honda Accord. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
