The Maserati Quattroporte is equipped with six airbags. Two front airbags, both dual-stage, protect the driver and front passenger in the event of collision, whilst their chests and hips are further protected by two side airbags located in the front seats. There are also two window airbags fitted in the roof next to the central pillar that protect the heads of the front and rear passengers if the car is struck from the side. The seatbelts, both front and rear, are fitted with electronically controlled pyrotechnic pretensioners and the latest generation load limiters. The system communicates with a sensor to determine the seriousness of a collision, and then instantly reels in the optimum amount of belt so that the body is effectively restrained. If the car is hit from behind, the active headrests of the two front seats automatically move closer to the passenger’s head to reduce the risk of whiplash injury.
