The B-segment is the 2nd category of the European segments for passenger cars, which is described as "small cars". It is equivalent to the subcompact category in the United States and the supermini category in Great Britain. The Euro NCAP vehicle class called “Supermini” also includes smaller A-segment cars.

Almost 50 images are not needed to define this category of cars. There already exit links to numerous models. Moreover, this article is not to be a complete list (past and present), every body style, etc. marketed in this category. Furthermore, it will be very difficult to keep the images up-to-date with the years of production in their descriptions. The flags do not represent the typical automobile firm's global supply chains. Cars made in one country end up being marketed in numerous international markets. Therefore, the national flags are superfluous. Thanks, CZmarlin (talk) 16:56, 19 July 2017 (UTC)

The article states that B-segment "is equivalent to the subcompact category in the United States and the Supermini category in Great Britain". Why then are there three articles? If they are regional variations of the same thing then, per WP:WORLDVIEW they should be merged. --Cornellier (talk) 11:44, 31 January 2019 (UTC) 1. I agree with merging the three, although I am not sure which is the best article name to merge the others into (*cue cultural wars between the brits, yanks and Euros!*) Cheers, 1292simon (talk) 21:20, 31 January 2019 (UTC) 1. 1.1. I would hesitate to merge them all. While subcompact, supermini, and B-segment have roughly the same meaning, there is no single term which can group them all together. Each article does a good job of keeping within its region of usage, i.e. North America, UK, and (rest of) Europe, respectively. Also, there's the precedent of other size classes having separate articles, like compact car and C-segment, and mid-size car and D-segment. Cit...
B-segment. Renault Clio, den bäst säljande modellen i segmentet. B-segment (eller Småbil) är en fordonsklassificering definierad av Europeiska kommissionen som det andra segmentet (efter A-segmentet och före C-segmentet) inom europeisk fordonsklassificering.
Supermini is a British car classification or vehicle size class for a small car, usually in a hatchback body style. It is an equivalent of the European B-segment or American subcompact categories. The term is also used by Euro NCAP for a size class including B-segment and the smaller A-segment cars.
