For enhanced safety, the front and rear seat shoulder belts of the Mercedes AMG GT have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Aston Martin DB12 doesn’t offer pretensioners for its rear seat belts.
The Mercedes AMG GT’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The DB12 doesn’t offer pre-crash pretensioners.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Mercedes AMG GT are reminded to check the back seat. The DB12 doesn’t offer a back seat reminder.
The Mercedes AMG GT has standard Active 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 DB12 doesn't offer collision warning or crash mitigation brakes.
The Mercedes AMG GT has a standard Post Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The DB12 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
Over 200 people are killed each year when backed over by motor vehicles. The Mercedes AMG GT has standard Close-Range Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The DB12 doesn’t offer backup collision prevention brakes.
The Mercedes AMG GT has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The DB12 doesn’t offer all-wheel drive.
Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The Mercedes AMG GT has Car-to-X Communication, a system that seemlesly communicates important warnings to the driver about impending danger, if they're available. The DB12 doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
Both the Mercedes AMG GT and DB12 have rear cross-traffic warning, but the Mercedes AMG GT has Active Brake Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The DB12’s Rear Cross Traffic Assist doesn’t automatically brake.
The Mercedes AMG GT has standard Mercedes-Benz Emergency Call, 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 DB12 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 Mercedes AMG GT and the DB12 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, blind spot warning systems, around view monitors, rear cross-path warning, driver alert monitors and available lane departure warning systems.
The Mercedes AMG GT weighs 526 to 628 pounds more than the Aston Martin DB12. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
