Grand Cherokee was redesigned for 2005, gaining size, power, and features. It's longer than the 1999-2004 version by 3.5 inches in wheelbase and 5 inches overall, but interior dimensions changed little. Laredo and upscale Limited models were offered. Both seated five; no 3rd-row seat was available. Laredos swapped a 195-hp 4.0-liter inline 6-cyl engine for a 210-hp 3.7-liter V6. Optional for Laredo and standard on Limited was a 230-hp 4.7-liter V8. Optional for Limited was parent-company Chrysler's 325-hp 5.7-liter Hemi V8. The 5.7 had Chrysler's Multi-Displacement System, which deactivates four cylinders at idle and in cruising to save fuel. Grand Cherokee's sole transmission was a 5-speed automatic with manual shift gate. V6 and 4.7-liter V8 models offered rear- or all-wheel drive. The 5.7 V8 came only with AWD. Each V8 used its own AWD system, but both include low-range gearing. Low-range gearing was unavailable for the AWD V6. All Grand Cherokees had antilock 4-wheel disc brakes, 17-inch wheels, and a rear liftgate with opening glass. An antiskid system was available on AWD versions. Optional were curtain side airbags designed to protect the head and torso for both seating rows. AWD V8s offered optional front and rear limited-slip differentials. Other new options included rear obstacle detection, satellite radio, DVD entertainment, and Chrysler's UConnect, which uses the audio system as a hands-free, wireless link to cell phones. Also available were navigation system, power-adjustable pedals, heated front seats, tire-pressure monitor, and an off-road package.
