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 Acadia are reminded to check the back seat if they opened the rear door before starting out. The Model X doesn’t offer a back seat reminder.
The Acadia 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 Model X doesn’t offer front seat center airbags.
Over 200 people are killed each year when backed over by motor vehicles. The Acadia has standard Reverse Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Model X doesn’t offer backup collision prevention brakes.
When descending a steep, off-road slope, the Acadia AT4’s standard Hill Descent Control allows you to creep down safely. The Model X doesn’t offer Hill Descent Control.
The Acadia has a standard HD Surround Vision to allow the driver to see objects all around the vehicle on a screen. The Model X 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.
To help make backing out of a parking space safer, the Acadia’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 Model X doesn’t offer a rear cross-path warning system.
The Acadia has standard OnStar®, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Model X doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Acadia and the Model X have standard driver and passenger frontal airbags, front and rear side-impact airbags, side-impact head airbags, front and rear 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, blind spot warning systems, rearview cameras, available all wheel drive and driver alert monitors.
