In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The GS F offers available headlight washers to keep headlight output high. The AMG GT 4-Door doesn’t offer headlight washers.

The AMG GT 4-Door’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The GS F’s optional adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

The GS F’s available rear sunshade is power operated, allowing the driver to remotely raise and lower it. The sunshade available in the AMG GT 4-Door is manual, and has to be raised or lowered in the rear.
