The F-segment is the 6th category and largest of the European segments for passenger cars, and always belongs to "luxury cars".[1][2][3]
The equivalent categories are full-size luxury sedan (or "large luxury sedan") in the United States, luxury saloon (or "luxury limousine") in the United Kingdom, and Oberklasse in Germany. Extended-wheelbase limousines and armored sedans are also considered as F-segment.
F-segment is a niche of the European market (approximately 0.2–0.3% in the 2010s) and the range is limited to only a few models.[4][5]
