For enhanced safety, the front seat shoulder belts of the Toyota bZ 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 bZ 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.
In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Toyota bZ achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The BMW i4 has not been tested.
When descending a steep, off-road slope, the bZ AWD’s standard Downhill Assist Control allows you to creep down safely. The i4 doesn’t offer Downhill Assist Control.
Both the bZ and i4 have rear cross-traffic warning, but the bZ has 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 bZ and the i4 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee 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.
