In fluid mechanics, drag is the force that opposes the movement of a body in a fluid. In the case of an automobile, the fluid that opposes the vehicle's forward motion is air. It is therefore in the interest of manufacturers to reduce this drag, the force that causes an increase in fuel consumption and a corresponding reduction in top speed.[1] The pressure at the front of a car is the pressure at the front of the vehicle.

The pressure at the front of an eco-mobile (in red) is a source of drag, even if this drag is paradoxically compensated almost entirely by depressions in the rest of the bodywork

For its part, the book "Aerodynamics of Road Vehicles" published by Wolf-Heinrich Hucho, citing Flegl and Bez, uses an average filling coefficient (or shape factor) of 0.81, established from the study of 85 European car models.[5] This shape factor is used to approximately calculate the frontal area.

The main drag, of the order of 2⁄3 of the total drag, is the "shape (or profile) drag." [3] It is due to two physical phenomena: on the one hand, the set of pressures on the front part of the vehicle body (overpressures and depressions) resulting, moreover, quite counter-intuitively, in a relatively low drag; and on the other hand, the effect of the depression remaining after the passage of the vehicle, which produces the so-called "base drag", which represents a significant part of the total drag (see below).[7][8] This is the main form factor of the "shape drag".

How we measure the cars in rows of seatsLength - In the front seats, minimum and maximum measured from the brake pedal to the backrest. In the rear, measured with a space in the front seats of 100 cm.

How we measure performance in AccelerationWe use the gear ratio(s) necessary to obtain the shortest time in this test. We start accelerating before the starting speed so that the engine is running at full load.RecoveryWe use only the indicated gear, unless it is necessary to engage a higher gear to reach the maximum engine speed. Acceleration starts before the starting speed so that the engine is running at full load.BrakingBraking starts at 140-130 km/h and is counted from 120 km/h until the vehicle comes to a stop.

Unfussy, but following a very Germanic pattern. Thus, the horizontal lines define the somewhat rough character of the Volkswagen T-Cross. An expressive front apron and a wide front grille shape their features, while the headlights are pointed towards the ends, accentuating the imposing expression that has, despite its contained dimensions.

On the sides, the main lines reinforce this impression, making use of a high shoulder line and highlighted by the wheel arches. At the rear, the differences with the subcompact Polo are especially noticeable in terms of height.

As standard equipment, the Volkswagen T-Cross comes with on-board computer, Composition Media Radio with 8-inch screen, variable rear seat, height adjustment for the driver's seat, front and rear windows, fatigue detector, LED taillights, fog lights with cornering light, speed limiter, plastic multifunction steering wheel and Front Assist.

We never tire of saying that, when talking about Chinese cars, we can find from cheap copies of poor quality to well-made limousines, which pretend to resemble (without succeeding) the most exclusive Rolls-Royce or Mercedes-Maybach... and even hypercars like the Hongqi S9! Today we want you to meet the Chery Tiggo 7 Pro.

It is a compact SUV sold in Brazil and measures 4.5 meters in length, 1.84 in width and 1.70 in height, with a wide wheelbase of 2.67 meters. Inside there is plenty of space available, although the trunk is somewhat short, with 450 liters.

Aesthetically, the Chery Tiggo 7 Pro is not a crude clone of a European model, although it does have some solutions already seen. For example, the front reminds us of the DS 7 CROSSBACK, while the light strip at the rear can be considered a classic among cars from the Old Continent.

Inside we find a modern image, thanks to a 12.3-inch digital instrumentation, a 10.25-inch central screen and haptic controls for dual zone automatic climate control. In addition, the multimedia system works with both Android Auto and Apple CarPlay.
