The GV70’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Blazer doesn’t offer pre-crash pretensioners.
Both the GV70 and Blazer have child safety locks to prevent children from opening the rear doors. The GV70 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 Blazer’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 GV70 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Blazer doesn’t offer front seat center airbags.
Using vehicle speed sensors and seat sensors, smart airbags in the GV70 deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The GV70’s side airbags will shut off if a child is leaning against the door. The Blazer’s side airbags don’t have smart features and will always deploy full force.
Over 200 people are killed each year when backed over by motor vehicles. The GV70 Advanced/Prestige has a standard Reverse Parking Collision-Avoidance Assist that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Blazer doesn’t offer backup collision prevention brakes.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the GV70. But it costs extra on the Blazer.
When descending a steep, off-road slope, the GV70’s standard Hill Descent Control allows you to creep down safely. The Blazer doesn’t offer Hill Descent Control.
The GV70 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 Blazer’s blind spot costs extra.
To help make backing out of a parking space safer, the GV70 has standard Rear Cross-Traffic Collision-Avoidance Assist and automatically engage the brakes. Chevrolet charges extra for Rear Cross Traffic Alert on the Blazer and the Blazer’s Rear Cross Traffic Alert does not include automatic braking.
The GV70’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 Blazer doesn’t offer a driver alert monitor.
Both the GV70 and the Blazer have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, 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 around view monitors.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the GV70 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 128 vehicles tested by the IIHS. The Blazer has not been fully tested, yet.
