Compared with off-road masters such as Land Rover Range Rover, q7 can only be said to be barely passable, but it is not a problem for Q7 to conquer them in the face of generally bad road conditions. The chassis height can be adjusted to increase the passability of q7, and ordinary bumps can pass easily. Quattro full-time four-wheel drive system with self-locking pure mechanical central differential is the dependence and guarantee of q7 off-road capability. The system provides 40: 60 front and rear driving torque distribution for q7, and the rear wheel can get up to 85% driving force when the front wheel slips, and vice versa.
