For enhanced safety, the front seat shoulder belts of the Chevrolet Blazer EV 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 SE Countryman doesn’t offer height-adjustable seat belts.
Both the Blazer EV and SE Countryman have child safety locks to prevent children from opening the rear doors. The Blazer EV has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The SE Countryman’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
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 Blazer EV are reminded to check the back seat if they opened the rear door before starting out. The SE Countryman doesn’t offer a back seat reminder.
Over 200 people are killed each year when backed over by motor vehicles. The Blazer EV offers optional Reverse Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The SE Countryman doesn’t offer backup collision prevention brakes.
The Blazer EV offers an optional HD Surround Vision to allow the driver to see objects all around the vehicle on a screen. The SE Countryman 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 Blazer EV’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 SE Countryman 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 Blazer EV’s standard Rear Cross Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side and Rear Cross Traffic Braking automatically engages the brakes to help avoid a collision. The SE Countryman doesn’t offer a rear cross-path warning system.
Both the Blazer EV and the SE Countryman 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, daytime running lights, lane departure warning systems, rearview cameras and available driver alert monitors.
The Chevrolet Blazer EV weighs 1309 to 1665 pounds more than the MINI SE Countryman. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
