The 718 Cayman Auto offers optional Porsche Active Safety, 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 SF90 doesn't offer collision warning or crash mitigation brakes.
The 718 Cayman has standard ParkAssist to help warn the driver about vehicles, pedestrians or other obstacles behind or in front of their vehicle. The SF90 doesn’t offer a front parking aid.
The 718 Cayman 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 SF90 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 718 Cayman and the SF90 have standard driver and passenger frontal airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available blind spot warning systems.
