For enhanced safety, the front and rear seat shoulder belts of the Volvo XC40 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 Chevrolet Trailblazer doesn’t offer pretensioners for its rear seat belts.
The XC40’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Trailblazer doesn’t offer pre-crash pretensioners.
Both the XC40 and Trailblazer have child safety locks to prevent children from opening the rear doors. The XC40 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 Trailblazer’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.
The XC40 has a standard Whiplash Protection System (WHIPS), which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the WHIPS allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. At the same time the pretensioning seatbelts fire, removing slack from the belts. The Trailblazer doesn’t offer a whiplash protection system.
The XC40 has standard Post-impact braking, which automatically apply 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 XC40 has a standard CTA Auto Brake 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 XC40. But it costs extra on the Trailblazer.
The XC40 offers an optional 360-Degree Surround View 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 XC40 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. A system to reveal vehicles in the Trailblazer’s blind spot costs extra.
To help make backing out of a parking space safer, the XC40 has standard Cross Traffic Alert and Braking 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 XC40’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 XC40 and the Trailblazer have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, 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 Volvo XC40 weighs 572 to 938 pounds more than the Chevrolet Trailblazer. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
