In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The S6 has standard headlight washers to keep headlight output high. The AMG GT 4-Door doesn’t offer headlight washers.

A power rear sunshade and manual rear side window sunshades are optional in the S6 Prestige to help block heat and glare for the rear passengers. The AMG GT 4-Door doesn’t offer rear side window sunshades.

The S6 has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the AMG GT 4-Door.
