The 911 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Portofino 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 Portofino doesn’t offer a night vision system.
Both the 911 and the Portofino have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rear parking sensors, available crash mitigating brakes, lane departure warning systems, blind spot warning systems and around view monitors.
