The MC20 offers optional Automated Emergency Braking, 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 812 doesn't offer collision warning or crash mitigation brakes.
The MC20 Cielo has a standard Surround View System to allow the driver to see objects all around the vehicle on a screen. The 812 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.
To help make backing out of a parking space safer, the MC20’s optional Rear Cross Path uses sensors in the rear to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The 812 doesn’t offer a rear cross-path warning system.
The MC20 has standard SOS and Assist Call, which uses a global positioning satellite (GPS) receiver and a cellular system to help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The 812 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 MC20 and the 812 have standard driver and passenger frontal airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, front and rear parking sensors and available blind spot warning systems.
