What do the letters S and E mean in cars?

[VanAlyssa]

E-Class and S-Class refer to Mercedes-Benz's E-Class and S-Class models. Here is some extended information: 1. Car Classification: At that time, cars were sold under a planned distribution model, with vehicle grades determined by engine displacement, thus categorizing them into micro cars, standard cars, mid-size cars, upper-mid-size cars, and luxury cars. 2. Differences: The E-Class features softer side lines with a cigar-shaped waistline; the S-Class has triangular headlights, giving it the most aggressive look, with more inclined rear lines, the longest body length, and the highest height. In the Mercedes-Benz lineup, the E-Class is considered an upper-mid-size car, while the S-Class is the top-tier luxury vehicle. The S-Class focuses on luxury, whereas the E-Class emphasizes comfort.
