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 750S 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 750S doesn’t offer a back seat reminder.
The Mercedes AMG GT has a standard Active Brake Assist, which uses forward mounted sensors to detect an immediately impending crash (warning the driver first if the available collision warning system is equipped) and automatically apply the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The 750S 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 750S 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 750S doesn’t offer backup collision prevention brakes.
The Mercedes AMG GT offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The 750S 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 seamlessly communicates important warnings to the driver about impending danger, if they're available. The 750S 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 and gently nudges the vehicle back towards its lane. The 750S doesn’t offer a lane departure warning system.
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 Rear Cross Traffic Brake automatically engages the brakes to help avoid a collision. The 750S 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 750S doesn’t offer a driver alert monitor.
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 750S doesn’t offer a GPS response system, 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 750S have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding and rearview cameras.
The Mercedes AMG GT weighs 1173 to 1281 pounds more than the McLaren 750S. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
