For enhanced safety, the front seat shoulder belts of the Toyota Prius Plug-In Hybrid are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW i4 doesn’t offer height-adjustable seat belts.
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 Plug-In Hybrid are reminded to check the back seat if they opened the rear door before starting out. The i4 doesn’t offer a back seat reminder.
The Toyota Prius Plug-In Hybrid offers an optional Panoramic View Monitor and it also offers an optional rear camera washer to make backing always safe, regardless of road dirt or grime, while the BMW i4 doesn’t offer a camera washer, requiring manual cleaning.
Both the Prius Plug-In Hybrid and i4 have rear cross-traffic warning, but the Prius Plug-In Hybrid offers optional Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The i4’s Cross Traffic Warning doesn’t automatically brake.
Both the Prius Plug-In Hybrid and the i4 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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, rear cross-path warning, driver alert monitors and available around view monitors.
