For enhanced safety, the front and rear seat shoulder belts of the Toyota Prius have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The BMW 2 Series Gran Coupe doesn’t offer pretensioners for its rear seat belts.
For enhanced safety, the front seat shoulder belts of the Toyota Prius 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 2 Series Gran Coupe 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 are reminded to check the back seat if they opened the rear door before starting out. The 2 Series Gran Coupe doesn’t offer a back seat reminder.
The Prius Limited offers an optional Panoramic View Monitor to allow the driver to see objects all around the vehicle on a screen. The 2 Series Gran Coupe 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.
Both the Prius and 2 Series Gran Coupe have rear cross-traffic warning, but the Prius offers optional Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The 2 Series Gran Coupe’s Cross Traffic Warning doesn’t automatically brake.
Both the Prius and the 2 Series Gran Coupe have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, 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 and driver alert monitors.
For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the Prius its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 36 vehicles tested by the IIHS. The 2 Series Gran Coupe last would have qualified as only a standard “Top Safety Pick” for 2019.
