The Grand Wagoneer’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The MDX doesn’t offer pre-crash pretensioners.
The Grand Wagoneer has standard Active Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Headrests system moves the headrests forward to prevent neck and spine injuries. The MDX doesn’t offer a whiplash protection system.
With its standard Full-Speed Forward Collision Warning Plus, the Jeep Grand Wagoneer is better at preventing collisions with pedestrians than the Acura MDX, according to the Insurance Institute for Highway Safety:
