Sedan
Overview
A sedan is a passenger car with a three-box structure where the engine compartment, passenger cabin, and trunk are each independent. Typically equipped with four doors and four to five seats, it offers an excellent balance of ride comfort and cargo space, making it one of the most common body styles worldwide. Sedans are used for a wide range of purposes, from urban driving to long-distance travel, and are available in various price ranges and classes, from luxury sedans to economical compact sedans.

History and Origins
The origins of the sedan date back to the early 20th century. Early automobiles were derived from horse-drawn carriages, but the concept of the modern sedan began to take shape in the 1910s with the emergence of enclosed bodies. In the 1920s, mass-produced models like the Ford Model T popularized the sedan, and later, in the 1950s and 1960s, large sedans reached their peak in the United States. In Japan and Europe, fuel-efficient compact sedans gained popularity after the oil shocks of the 1970s.
Structural Characteristics
The most distinctive feature of a sedan is its three-box structure. The engine compartment (front), passenger cabin (mid), and trunk (rear) are clearly separated, which provides advantages in occupant protection during collisions and relatively low noise and vibration. Additionally, the trunk is isolated from the passenger cabin, preventing cargo odors or noise from entering the interior. Suspension is generally designed with a focus on ride comfort, and the lower body compared to hatchbacks or SUVs offers better aerodynamic efficiency.
Types of Sedans
- Compact Sedan: Features a small engine and compact body, offering good fuel economy and suitability for city driving. Examples: Hyundai Avante, Toyota Corolla.
- Midsize Sedan: Medium-sized, popular for families, with a good balance of interior space and performance. Examples: Honda Accord, BMW 3 Series.
- Full-size Sedan: Large body and powerful engine, primarily sold in the luxury market. Examples: Mercedes-Benz S-Class, BMW 7 Series.

Latest Trends
As of 2024–2025, the sedan market is experiencing a decline in market share due to the rapid growth of SUVs and crossovers. However, in the transition to electric vehicles (EVs), sedans benefit from aerodynamic advantages to maximize driving range, drawing attention to electric sedans such as the Tesla Model 3, Hyundai Ioniq 6, and BMW i4. Additionally, autonomous driving technology and connected car features are being rapidly introduced, especially in luxury sedans. Emerging manufacturers like China's BYD and XPeng are expanding their market share in the electric sedan segment by leveraging price competitiveness. In the luxury sedan market, electrification is accompanied by an emphasis on ultra-premium customization options.
