Why does the upper part of the arch on the flat cars?

That’s why most modern cars have a flat bottom part of the wings

The design of cars is constantly changing, and it is important to note that not only the visible part of it. Often important trends townsfolk pass by, undetected by them, but leaving an indelible mark in the history of design.

Here is a very vivid example.

Do you know what “the curve of the Hofmeister”? No never even heard of him? Meanwhile, without this element of the exterior can not imagine any BMW from the 60-ies of XX century:

Here it is on the model BMW 2000 CS

But his interpretation of the latest flagship sedan 2019 BMW 7-Series:

It would seem that the trinket, but without it BMW format would be completely different.

Today, there is an extremely common trend of design, which may have also slipped past you. Meanwhile, she slowly grabs a novelty, encountered on the road, after another. This item is only couple of inches wide on all four wheels and, it seems, will not bear practical use. Until now, its purpose remains a mystery.

Okay, maybe it sounds a little dramatic and smacks of yet another conspiracy of the automakers, however, there is the existence of a very common design features on the body. Here is the plane, surrounding the wheel, which previously was never part of the design of old cars.

Yeah, the Lada Vesta, it is also present

Assumptions about the use of flat koncowek wings move in different ways: someone suggests that this is done to improve aerodynamics. Others believe that the way designers visually enlarge the wheel arches. Others err on the features of the production.

American automotive website Jalopnik have also asked this kind of question and dug deeper in search of the truth, appealed directly to avtodizayner John Mayer, who is now in Volvo. Here is what he said:

“The flat part of the wheel arch on the bottom edge, which is common on most cars these days, helps to structurally support the metal stamping and in this area. We also added what we call the “sickle” – a kind of slight stylistic undercut, first shown in concept coupe 2013.

A similar bend on the metal sheet helps to keep the shape. If you’re somewhere doing the crease, it is usually better to hold a given shape”.

The design element we’re talking about:

Increase:

Thus, we can state the fact that the original goal of including “flattened arch” in the design of structural support for the stamped panels. That is, the increase of stiffness of the element. But every automaker makes the everyday element of their own stylistic nuances, making a holistic perception of the car on a subconscious level unique.
