The 911 (except GT3) has standard Warn and Brake Assist, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Revuelto doesn't offer collision warning or crash mitigation brakes.
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 Revuelto doesn’t offer automatic braking for stationary objects directly to the rear.
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 Revuelto doesn’t offer a night vision 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 Revuelto doesn’t offer a driver alert monitor.
Both the 911 and the Revuelto have standard driver and passenger frontal airbags, front side-impact airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems, around view monitors and rear cross-path warning.
