Many people may have this feeling, the car running on the road, from the side, many are low in front and high in the back, especially some models with more affordable prices, this trend is particularly obvious. However, for those luxury brand sedans, the body lines appear to be more stable and coordinated, and the height difference between the front and rear is not obvious, which looks more calm and atmospheric. So the question is, why don't some car companies design their cars more atmospheric? Is it because you don't want to? Actually, no, of course, manufacturers also want better looking designs, but they are often more than willing to do so.

From an engineering point of view, most sedan chassis are designed to be low in the front and high in the rear, and there are several key factors behind this that determine the prevalence of this phenomenon.

First of all, the influence of the drive mode cannot be ignored. Most sedans are designed with front-wheel drive, and in order to ensure that the front wheels have enough grip, the body needs to concentrate the weight as much forward as possible. If the front and rear heights are exactly the same, or the front is high and the rear is low, the vehicle's center of gravity will change, affecting the driving force of the front wheels, and then affecting the vehicle's driving stability and safety.

Secondly, ride comfort is also an important consideration. The seating layout of the sedan determines the distribution of legroom for passengers. The front seats are located close to the instrument panel, allowing passengers to partially extend their legs under the center console, so the seats are designed low without compromising comfort. In the rear seats, it is difficult for passengers to fully extend their legs, and if the seat height is too low, the legs will form a large angle, and the ride experience will be worse. In order to improve the comfort of rear passengers, the seats must be raised appropriately, and once the seat height is raised, the corresponding window and roof space must also be adjusted, so that the rear height of the car naturally increases.

In addition, the load variation of the vehicle is also one of the key factors affecting the design of the body height. The rear of the sedan not only carries the passengers, but also the weight of the trunk. Between full load and no load, the difference in weight on the rear bearing is very significant. If the chassis height is not enough, the compression space of the rear suspension system at full load will be limited, affecting the vehicle's carrying capacity and comfort. Therefore, many sedans are designed to reserve a certain amount of rear suspension compression space, so that the rear chassis is slightly raised.

After understanding these basic design logics, let's look at how the price factor affects the body stance. Why do luxury cars look smoother, while regular cars appear lower in the front and higher in the rear? The answer is actually quite simple, the core reason is the length of the body.

The longer the body, the easier it is for the front and rear height difference to be smoothly transitioned. For example, a mid-to-large sedan of a luxury brand, such as a car with a length of 3 mm, even if the rear of the car is 0 cm higher than the front of the car, the average height increase to each meter of vehicle length is only 0.0 cm, and the obvious tilt is almost imperceptible visually. And a compact car, such as a model with a length of 0 mm, if there is also a height difference of 0 cm, the height growth per meter of vehicle length will reach 0.0 cm, and this trend of low front and high rear will be particularly obvious.

In addition, luxury brands tend to have more advanced chassis tuning technology, which can further optimize the body posture through air suspension and other configurations, so that the difference in front and rear height is less obvious. However, ordinary models are limited by cost and usually adopt a more traditional suspension design, which is naturally difficult to achieve such a balance in terms of visual perception.

At the end of the day, the car is a tool, and its core value is still to provide people with a convenient and comfortable travel experience. As for whether the body stance is elegant enough, it is a matter of opinion.
