The 2008 Jeep Grand Cherokee had only small, cautious changes to the exterior, with the interior improved considerably more, and the base V8 upgraded most of all. Off-road angles improved across the board, ground clearance went up slightly, and aerodynamics were unchanged.
In appearance, the grille was extended downward, and the headlights given more obvious curves; fog lamps were lowered and the front fascia was made into two pieces, so serious off-roaders can remove the bottom half.
Perhaps most welcome to the average buyer, the 4.7-liter V-8 liter engine was reworked, with major gains in power and small gains on mileage.
American Grand Cherokees gained a new option, the Mercedes 3-liter V6 diesel. The Hemi and SRT Hemi options remained; transmissions were five-speeds, with the Mercedes unit on the V6, a different Mercedes unit (W5J400) on the diesel, and the 545RFE on the V8s.
As for transfer cases, only the V6 came with the New Venture NV140 single-speed, full-time unit; the rest had the NV245 two-speed, with a 2.72:1 low range ratio and 48/52 front/rear torque split. This one had an electronic limited-slip differential, and was optional on the gasoline V6 as well as the others. Both were carryovers from past Grand Cherokees.
New options were auto-leveling high-intensity discharge headlamps, hard-drive stereo, and a rear-seat streaming TV system. The projected Overland and SRT-8 gained heated rear seats and power-ventilated front seats.
The “MyGIG” stereo had a touch-screen and took voice commands, with a 20-gigabyte hard drive to store music, photos, and voice memos; it also had real-time traffic with trip rerouting. Other options were a backup camera, backup sensors, auto high beams, rain-sensing wipers, memory seats and mirrors, iPod connectivity, and 18-inch chrome-clad aluminum wheels.
New technologies included Hill Descent Control, Hill Start Assist, and Trailer Sway Control.
The interior was also modified, with a two-tone instrument panel, soft-touch surfaces, updated styling, and a standard tilt and telescoping steering column. The Limited adds two-tone leather and bright chrome accent rings, and the Overland had real wood steering wheel rim. LED illumination was brightened; on Limited and Overland, a dark-tinted lens faded to reveal the gauges when the car started. Overland also gained Saddle perforated leather seats.
* Without air suspension. With: ground clearance 10.6, angles 34.3, 23.1, and 29.3
The 2009 Grand Cherokee’s Hemi engine was upgraded to 357 horses and 389 lb-ft of torque with better mileage. The instrument panel was upgraded to include tire pressure monitoring and fuel saver notification, but the fuel saver notification was dropped. The rear DVD went to a 9 inch screen; and an iPod interface was optional. A leather group became optional on Limited and Overland. The SRT8 got the Performance Pages system, better leather, and a bigger DVD screen.
For 2010, the Grand Cherokee lost the 4.7 V8. Laredo X became, for Canada, Laredo North Edition, with 17-inch wheels, power sunroof, upgraded stereo, backup camera, and rear parking assist. An automatic oil change monitoring system was added, standard, and Overland was dropped.
