What class is the BMW 4 Series?

[VonBrandon]

BMW 4 Series is a sporty B-segment car under the BMW brand, equipped with three different engines. Criteria for vehicle classification: Vehicle classification is primarily based on factors such as wheelbase, engine displacement, weight, and body dimensions, with the most common method being differentiation by body size and wheelbase length. In fact, this classification method originates from Volkswagen's internal grading system, but most car owners in China also use this approach to categorize vehicle classes. Vehicle classification levels: According to the German vehicle classification standard, A-segment cars include A0 and A00 classes, generally referring to compact cars; B-segment cars are mid-size sedans; C-segment cars are executive cars; while D-segment cars denote luxury sedans. The classification is mainly based on parameters like wheelbase, displacement, and weight, with later letters in the alphabet indicating longer wheelbases, larger displacements and weights, and progressively higher levels of luxury in the vehicles.
