What do the A-segment, B-segment, and C-segment of cars refer to?
2 Answers
A-segment cars are typically compact cars, while B-segment cars are usually mid-size cars. C-segment cars are medium and large-sized vehicles. The definitions of the A-segment, B-segment, and C-segment of cars are as follows: 1. A-segment: A-segment cars are currently the best-selling models in the market, with a length of 4.2 to 4.6 meters and a wheelbase of 2.5 to 2.7 meters. The performance of A-segment cars in all aspects can already meet the needs of most families. 2. B-segment: The size is significantly larger, with car lengths ranging from 4.3 to 5 meters and a wheelbase between 2.7 to 2.9 meters. A common example is the Volkswagen Passat. 3. C-segment: C-segment cars are often referred to as executive-level cars. They are usually longer than 5 meters, with a wheelbase of 2.9 to 3 meters. They are typically well-equipped in all aspects and have larger engine displacements.
I've worked in the sheet metal shop for over 20 years, and car ABC surfaces are categorized by importance. The A-surface refers to the exterior body panels you can directly touch with your fingers, like doors and hoods - the most visible areas where even fingerprint marks need to maintain aesthetic appeal. B-surfaces are those less noticeable but functional areas, such as door frame inner edges or bumper seams, with slightly looser tolerance requirements than A-surfaces. C-surfaces are completely hidden, like support beams behind interior panels or in chassis layers - as long as safety isn't compromised, a 2-3mm size variation doesn't matter. Last time a car got rear-ended, we spent a week meticulously reshaping the A-surface curvature, while the C-surface beam head was just gas-cut and welded in half an hour.
