It has been studied and developed to guarantee the highest traction and torque as well as comfort in all conditions, with optimised consumption. Q4 is an exclusive all-wheel-drive Maserati system; intelligent and active:- Intelligent: the Q4 system is able to engage traction on the front wheels, that are otherwise passive, only when needed in order to lower consumption and enhance handling.- Active: the Q4 system varies continuously, moment by moment, and processes a wide range of parameters to distribute torque to all four wheels as required.
