The Portofino offers optional crash mitigation brakes, 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 DB11 doesn't offer collision warning or crash mitigation brakes.
The Portofino’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The DB11 doesn’t offer a lane departure warning system.
To help make backing out of a parking space safer, the Portofino’s optional rear cross-path warning system uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The DB11 doesn’t offer a cross-path warning system.
The Portofino has standard GPS Response System, which uses a global positioning satellite (GPS) receiver and a cellular system to send emergency personnel to the scene if any airbags deploy. The DB11 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 Portofino and the DB11 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, front and rear parking sensors, available blind spot warning systems and around view monitors.
