The Countryman has a standard PostCrash iBrake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Trailblazer doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
Over 200 people are killed each year when backed over by motor vehicles. The Countryman has standard Rear Collision Prevention that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Trailblazer doesn’t offer backup collision prevention brakes.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Countryman. But it costs extra on the Trailblazer.
The Countryman offers an optional 360-degree camera to allow the driver to see objects all around the vehicle on a screen. The Trailblazer only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.
The Countryman has a standard blind spot warning system that 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. A system to reveal vehicles in the Trailblazer’s blind spot costs extra.
To help make backing out of a parking space safer, the Countryman has standard Cross Traffic Warning and Brake Intervention automatically engages the brakes to help avoid a collision. Chevrolet charges extra for Rear Cross Traffic Alert on the Trailblazer and the Trailblazer’s Rear Cross Traffic Alert does not include automatic braking.
The Countryman’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Trailblazer doesn’t offer a driver alert monitor.
Both the Countryman and the Trailblazer have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems and rearview cameras.
The MINI Countryman weighs 488 to 807 pounds more than the Chevrolet Trailblazer. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
The MINI Countryman achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The Trailblazer has not yet been fully evaluated by the IIHS for 2024.
