Interior

The 2018 Mercedes-Benz SL-Class is built more for comfort than performance. Taller and larger drivers will find plenty of space, and the wide range of seat adjustments ensure almost all passengers will find ideal seating position. The multi-contour seats further enhance the comfort with side bolsters adjustment for lateral support and massage functions to reduce fatigue on long distance traveling. In hot weather, the sun-reflected skin and a cooled seat will keep you from overheating, and when the weather changes, the Airscarf will keep you comfortable with warm breezes behind the neck.

The material quality is excellent throughout the cabin, qualified for cars in the high price range. Like other Mercedes vehicles, the COMAND infotainment system takes a little time to adapt, but after a while the menu is very easy to use.

The 2018 Mercedes-Benz SL-Class also offers a Magic Sky roof that allows you to enjoy a clear sunroof panorama or switch to dark glass using just a button. There’s still an open-top touring attraction, and now the power-folding top can be operated at speeds up to 25 mph. The wind noise is kept by the windblocker power, allowing you to have a conversation on the highway without raising your voice.

Convertibles with folding hardtop roofs usually provide only very little cargo space when the top is down, but the 2018 SL-Class is able to provide a decent 8.5 cubic feet capacity. With the roof up, there are 13.5 cubic feet available. The hands-free trunk opener makes loading easier by popping the trunk with swiping your feet under the rear bumper.
