Over 200 people are killed each year when backed over by motor vehicles. The 911 (except Manual/GT3) offers an optional Maneuvering Assist that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The 12Cilindri doesn’t offer backup collision prevention brakes.
The 911 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The 12Cilindri doesn’t offer all-wheel drive.
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 12Cilindri doesn’t offer a night vision system.
The 911 offers an optional Surround View to allow the driver to see objects all around the vehicle on a screen. The 12Cilindri doesn’t offer any parking assist system.
To help make backing out of a parking space safer, the 911’s optional Rear Cross Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side and automatically engage the brakes. The 12Cilindri doesn’t offer a rear cross-path warning system.
The 911’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The 12Cilindri doesn’t offer a driver alert monitor.
Both the 911 and the 12Cilindri have standard driver and passenger frontal airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, lane departure warning systems, and available blind spot warning systems.
