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 Prius Prime are reminded to check the back seat if they opened the rear door before starting out. The Model 3 doesn’t offer a back seat reminder.
The Prius Prime XSE Premium offers an optional Panoramic View Monitor to allow the driver to see objects all around the vehicle on a screen. The Model 3 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 Prime’s standard Rear Cross Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side and automatically engages the brakes to help avoid a collision. The Model 3 doesn’t offer a rear cross-path warning system.
The Prius Prime has standard Safety Connect™, which uses a global positioning satellite (GPS) receiver and a cellular system to help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Model 3 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Prius Prime and the Model 3 have standard driver and passenger frontal airbags, front side-impact 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, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras and driver alert monitors.
The Toyota Prius Prime achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The Model 3 has not yet been fully evaluated by the IIHS for 2024.
