What is a Sedan?

Small cars generally refer to models with engine displacements around 1.0-1.3 liters. However, the distinction between micro cars, small cars, and other similar vehicle categories has become increasingly blurred. The classification is usually determined by the manufacturer's positioning and the predecessor model of the vehicle. Compact Cars: Also known as A-segment vehicles, these are the most common family cars, typically featuring wheelbases between 2.5-2.7 meters and engine displacements around 1.6-2.0 liters. In China, compact cars including domestic brands, joint venture models, and pure imports have become the mainstay of the current automotive market. Midsize Cars: These generally refer to vehicles with wheelbases ranging from 2.7 to 2.9 meters, body lengths between 4.6 to 4.9 meters, engine displacements typically from 2.0 to 3.0 liters, and seating for five passengers.
As an ordinary office worker, I think sedans are the most common type of family car, convenient for commuting. They usually have four doors and a separate trunk, unlike SUVs with their high ground clearance which can feel bulky. I've driven a few models, like the Honda Civic—its chassis is stable and doesn't wobble when turning, with reasonable fuel consumption of about 7-8 liters per 100 km in city stop-and-go traffic, which isn't expensive. The trunk is spacious enough for suitcases, making it suitable for family trips; the seats are soft, so long drives don’t strain your back. The price is also affordable, starting at around 100,000 yuan for a new car, and it holds decent resale value—you can still sell it for tens of thousands after a few years. Safety-wise, it comes standard with ABS and dual airbags, reliable enough for daily use.
From a mechanical design perspective, compact cars are quite fascinating. They utilize unibody construction to reduce weight and improve fuel efficiency. The common front-wheel-drive system with transversely mounted engines provides direct power delivery and enhances cornering performance. The chassis tuning prioritizes comfort, featuring independent rear suspension that effectively absorbs road imperfections. Excellent aerodynamics result in low drag coefficients, significantly reducing high-speed noise. The steel-aluminum hybrid material composition achieves an optimal balance between lightweight properties, structural rigidity, cost, and durability. Modern models integrate electronic stability programs that demonstrate remarkable anti-skid performance on slippery surfaces. Having tested multiple variants, I find this feature particularly practical for ensuring driving safety.
