The AMG S-Class’ pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The GS F doesn’t offer pre-crash pretensioners.

The AMG S 63 Sedan has all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The GS F doesn’t offer all-wheel drive.

An active infrared night vision system optional on the AMG S-Class helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera and near-infrared lights to detect heat, the system then displays the image on a monitor in the dashboard. The GS F doesn’t offer a night vision system.

The AMG S-Class offers an optional Surround View Camera to allow the driver to see objects all around the vehicle on a screen. The GS F 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.

Both the AMG S-Class and the GS F have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, driver alert monitors and available rear cross-path warning.

The Mercedes AMG S-Class weighs 772 to 935 pounds more than the Lexus GS F. The NHTSA advises that heavier cars are much safer in collisions than their significantly lighter counterparts.

The AMG S 65 Sedan offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Lexus doesn’t offer an active suspension on the GS F.

The AMG S-Class has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The GS F doesn’t offer a load leveling suspension.
