The Acadia Denali’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The MKC doesn’t offer pre-crash pretensioners.
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 MKC 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 MKC doesn’t offer front seat center airbags.
The Acadia (except SL/SLE) offers optional Forward Automatic Braking, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The MKC offers an available collision warning system without the automated brake feature that would prevent or reduce the collision if the driver fails to react.
The Acadia Denali offers an optional Surround Vision System to allow the driver to see objects all around the vehicle on a screen. The MKC 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.
Both the Acadia and the MKC have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras, available all wheel drive, lane departure warning systems, blind spot warning systems and rear cross-path warning.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the Acadia the rating of “Top Pick” for 2017, a rating granted to only 110 vehicles tested by the IIHS. The MKC has not been fully tested, yet, but doesn’t qualify for 2017 “Top Pick.”
