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 Nissan GT-R 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 GT-R 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 GT-R doesn’t offer a back seat reminder.
The Mercedes AMG GT 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 GT-R doesn’t offer knee airbags.
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 GT-R 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 GT-R 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 GT-R doesn’t offer backup collision prevention brakes.
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 GT-R doesn’t offer a system that can receive automated systems from infrastructure or other vehicles.
The Mercedes AMG GT’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The GT-R doesn’t offer a lane departure warning system.
The Mercedes AMG GT has a standard Surround View System to allow the driver to see objects all around the vehicle on a screen. The GT-R 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.
The Mercedes AMG GT’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 GT-R 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 Mercedes AMG GT’s standard Rear Cross-Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side and Active Brake Assist automatically engages the brakes to help avoid a collision. The GT-R doesn’t offer a rear cross-path warning system.
The Mercedes AMG GT’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 GT-R doesn’t offer a driver alert monitor.
Both the Mercedes AMG GT and the GT-R have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.
