The Aston Martin DB12 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Roma doesn’t offer knee airbags.
The DB12 has standard head airbag curtains for front and rear seats which act as a forgiving barrier between the driver and outboard passenger's upper bodies and the window and pillars. Combined with high-strength steel door beams and lower side airbags this system increases head protection in broadside collisions. The Roma doesn't offer side airbag protection for the head and are only available for the front seats.
The DB12’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The Roma doesn’t offer a lane departure warning system.
The DB12 has a standard Birds-eye Camera to allow the driver to see objects all around the vehicle on a screen. The Roma only offers front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
The DB12’s blind spot warning system uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The Roma doesn’t offer a system to reveal objects in the driver’s blind spots.
To help make backing out of a parking space safer, the DB12’s standard Rear Cross Traffic Assist uses sensors in the rear to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Roma doesn’t offer a rear cross-path warning system.
The DB12’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 Roma doesn’t offer a driver alert monitor.
Both the DB12 and the Roma 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 and front and rear parking sensors.
