For enhanced safety, the front seat shoulder belts of the Hyundai Nexo 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 Nexo Limited has a standard Surround View Monitor to allow the driver to see objects all around the vehicle on a screen. The Cooper SE 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.
The Nexo’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 and moves the vehicle back into its lane. 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 Nexo’s standard Rear Cross-Traffic Collision Warning uses sensors in the rear to alert the driver to vehicles approaching from the side and Rear Cross-Traffic Collision-Avoidance Assist automatically engages the brakes to help avoid a collision. The Cooper SE doesn’t offer a rear cross-path warning system.
Both the Nexo and the Cooper SE have standard driver and passenger frontal airbags, front side-impact 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 and driver alert monitors.
The Hyundai Nexo weighs 847 to 974 pounds more than the MINI Cooper SE. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
