To maximize occupant safety, the front seat shoulder belts of the Porsche 911 have pretensioners to eliminate dangerous slack in the event of a collision. The Maserati GranTurismo Folgore doesn’t offer pretensioners.
A passive infrared night vision system optional on the 911 helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The GranTurismo Folgore doesn’t offer a night vision system.
The 911’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 GranTurismo Folgore.
The 911 offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The GranTurismo Folgore 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.
Both the 911 and GranTurismo Folgore offer rear cross-traffic warning, but the 911 with Rear Cross Traffic Alert also has Rear Cross Traffic Alert (automatically applies the brakes) to better prevent a collision when backing near traffic. The GranTurismo Folgore’s Rear Cross Path doesn’t automatically brake.
The 911 has standard Porsche Connect, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The GranTurismo Folgore doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the 911 and the GranTurismo Folgore have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available crash mitigating brakes and blind spot warning systems.
