For enhanced safety, the front seat shoulder belts of the Toyota Prius Prime 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 MINI Cooper SE doesn’t offer height-adjustable seat belts.
The Prius Prime has standard Active Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Headrests system moves the headrests forward to prevent neck and spine injuries. The Cooper SE doesn’t offer a whiplash protection system.
Over 200 people are killed each year when backed over by motor vehicles. The Prius Prime Limited has standard Parking Support Brake that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Cooper SE doesn’t offer backup collision prevention brakes.
The Prius Prime Limited’s blind spot warning system uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The Cooper SE doesn’t offer a system to reveal objects in the driver’s blind spots.
To help make backing out of a parking space safer, the Prius Prime Limited’s standard cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Cooper SE doesn’t offer a cross-path warning system.
Both the Prius Prime and the Cooper SE have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, driver alert monitors and available rear parking sensors.
For its top level performance in IIHS driver-side small overlap frontal, moderate overlap frontal, side impact, rear impact and roof-crush tests, its standard front crash prevention system, its “Acceptable” rating in the new passenger-side small overlap crash test, and its headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the Prius Prime the rating of “Top Pick” for 2019, a rating granted to only 162 vehicles tested by the IIHS. The Cooper SE has not been tested, yet.
