Euro car segments

The A-segment is the first category in the passenger car classification system defined by the European Commission. It is used for city cars, the smallest category of passenger cars defined.

The D-segment is the 4th category of the European segments for passenger cars, and is described as "large cars".

The C-segment is the 3rd category of the European segments for passenger cars and is described as "medium cars". It is equivalent to the Euro NCAP "small family car" size class, and the compact car category in the United States.

The B-segment is the second smallest of the European segments for passenger cars between the A-segment and C-segment, and commonly described as "small cars". The B-segment is the third largest segment in Europe by sales volume, accounting for 15.5% percent of total car sales in 2024 according to JATO Dynamics. B-segment cars include hatchback, saloon, estate, coupe/convertible, MPV, and crossover/SUV body styles.

The E-segment is the 5th category of the European segments for passenger cars, synonymous with the term executive car.

The F-segment is the 6th category and largest of the European segments for passenger cars, and always belongs to "luxury cars".

S-segment cars are a European car segment class for sports coupés. The equivalent Euro NCAP class is called "roadster sport".
