It's not clear how these images were obtained by Carscoops, but they show a number of exterior and interior upgrades.
Up front, the revised Summit features a new front bumper, which does away with the scalloping and false vents under the headlights. There's also a subtly revised lower intake area, thin cutouts for the fog lights, and a blacked out area surrounding the chrome-laden grille. There's also a new, more intricate alloy wheel design.
On the inside, the updated range-topping Summit is now available with two-tone white and black leather, featuring quilted elements for the seats' bolsters and door trim.
It's not yet known whether the upgraded Summit will feature any changes to its mechanical or electronics package. Also unknown. at this stage, is whether any of the slight visual changes to the front fascia will be applied to lesser models in the Grand Cherokee range.
With the show in the Big Apple kicking off on Wednesday, New York time, we won't have long to find out.
