The doors have an opening angle larger (hind 78th instead of 67th). The drag coefficient improved from 0.40 to 0.37, while torsional rigidity is 146 percent higher. The tires are 17 or 18 "may also have a 20".

Jeep Grand Cherokee. 2010.The Grand Cherokee model has five seats. The rear seats do not move longitudinally, but may vary 24 º tilt of the backups (image).

Levels "Off-road is for driving off-road and level" Aero "to improve aerodynamics on the highway. These three heights are automatically adjusted, the other two (normal and "Park") if the driver can select.

The system "Quadra-Drive II is more evolved. Works like the "Quadra-Trac II but also has front and rear locking differential. The "Quadra-Drive II can combine the effect of locking differentials and brakes.
