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 McLaren GTS doesn’t offer pre-crash pretensioners.
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 McLaren GTS 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 McLaren GTS 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 McLaren GTS 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 McLaren GTS 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 McLaren GTS 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 McLaren GTS 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 McLaren GTS 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 McLaren GTS 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 Rear Cross Traffic Brake automatically engages the brakes to help avoid a collision. The McLaren GTS 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 McLaren GTS 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 McLaren GTS 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 McLaren GTS have standard driver and passenger frontal airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.
The Mercedes AMG GT weighs 981 pounds more than the McLaren GTS. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.
