This system is developed to deliver the hallmark Maserati rearwheel- drive experience, even when grip is poor. In normal conditions, the Q4 system sends all torque to the rear wheels, for perfectly balanced Maserati driving dynamics and optimal fuel consumption.
If traction is lost due to sudden acceleration or low grip on the rear axle, Q4 can alter the torque split from 100 per cent rear-wheel drive to 50-50 between the front and rear wheels. It all happens in an imperceptible 150 milliseconds – or less than the blink of an eye. Torque vectoring and a mechanical Limited-Slip Differential at the rear axle, unique for this class of vehicle, also provide essential support when it comes to dynamic driving stability.
