For enhanced safety, the front and rear seat shoulder belts of the Maserati Quattroporte have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Chrysler 300 doesn’t offer pretensioners for its rear seat belts.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Quattroporte. But it costs extra on the 300.
The Quattroporte’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the 300.
The Quattroporte has a standard Surround View Camera to allow the driver to see objects all around the vehicle on a screen. The 300 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
The Quattroporte has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. Only the 300 S/Touring L offers a blind spot warning system.
To help make backing out of a parking space safer, the Quattroporte has standard Rear Cross Path, helping the driver avoid collisions. Only the 300 S/Touring L offers Rear Cross Path Detection.
Both the Quattroporte and the 300 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.
