Fourth generation (W177, 2018-present) · Premium family hatchback
The W177 A-Class uses Mercedes' signature turbine-style air vents - round barrels that rotate in their housings. Vent-clip mounts designed for slat vents cannot grip these; look for turbine-vent-specific clips (some brands offer Mercedes-specific fitments), or default to adhesive dash or console mounts.
Three products we would look at first in this category. Fit for your Mercedes-Benz still comes first: check the compatibility list on the listing against your exact model and year, and read the model guide above.
