The Prius has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Accord doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
The Prius has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Accord doesn’t offer all-wheel drive.
The Prius Limited offers an optional Panoramic View Monitor 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 Prius has standard Rear Cross Traffic Alert to warn the driver of approaching traffic and automatically engage the brakes to help avoid a collision. Only the Accord EX/Sport/EX-L/Touring offers Cross Traffic Monitor and the Accord’s Cross Traffic Monitor does not include automatic braking.
Both the Prius and the Accord have standard driver and passenger frontal airbags, front and rear side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, front wheel drive, 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, rearview cameras and driver alert monitors.
