"We won't announce pricing until closer to launch in the summer," wrote Todd Goyer, a Jeep spokesman, in response to a query from Edmunds.
They include auto-folding power mirrors, headlight washers, blind-spot detection, forward-collision warning, adaptive cruise control and lane-departure warning and parallel and perpendicular park assist.
The Summit comes with a standard 4x4 system.
It is equipped with a standard 3.6-liter Pentastar V6 engine. Optional engines include a 5.7-liter V8 and a 3.0-liter Ecodiesel V6. All engines are linked to a standard eight-speed automatic transmission.
Exterior changes include an updated front fascia, grille and LED fog lamps, with new 20-inch polished-aluminum wheels.
The cabin features a new Laguna leather interior in Indigo and Sky Gray, one of four color treatments.
Edmunds says: As the name implies, car shoppers who want the ultimate Jeep Grand Cherokee should put the Summit on their consideration lists.
