Translation of "Cw-wert" in English

Only the Mercedes Concept IAA concept car achieves a Cd value of 0.19.

The car manufacturers mostly just publish the CW-values of their vehicles.

As a result, the optimized air flow leads to an improved fuel consumption and a lower cW value.

Of course, apertures are also bad for the drag coefficient, and should be avoided.

When did the Cd value start playing such an important role?

Drag coefficient (Cd) reduced from 0.26 to 0.23 (BMW 320d).

Its low drag coefficient of just 0.32 also enhances fuel efficiency considerably.

The lower Cd the easier it is for the air to pass the obstacle.

The side panels improve the Cd value of the Krone Profi Liner Efficiency by 5.2 percent.

The estate offered a Cd of 0.32 in standard form and 0.33 in Sport trim.

The aerodynamics of the car were also improved, the Cw improved from 0,31 to 0,32 to 0,29.

The cp value of 0.29 is more than nine percent lower than in the case of the predecessor model.

The separation region which creates air resistance is thus reduced over the entire width of the vehicle and the CW value is reduced.

Favourable aerodynamic shape (the wire is not located in the air stream, so the Cw value is lower).

With a Cd value of 0.27, the new Mercedes-Benz C-Class is the most aerodynamically efficient notchback saloon in its market segment.

From the friction constantF0 the drag coefficient (cw value) for the cylindrical pendulum bob can be estimated.

Keep resistance low The drag coefficient (CW value), cross-sectional area and speed all affect the air resistance that the vehicle must overcome.

With a Cd value of only 0.12, it is optimally designed for solar racing.

The new double-decker's Cd figure stands at 0.35, setting the benchmark in this vehicle segment.

What's more, this SUV sets another benchmark in its class with a low drag coefficient of 0.33.

The drag coefficient is lower the more drop-shaped the car is designed.

This light weight combined with the car's streamlining (with a coefficient of drag said to be Cd 0.26) allows for top speeds of for standard sedans and for the Tigre.

Principal advantages achieved by the invention are that the spoiler arrangement, which consists of two parts which are hinged to one another, in its moved-out operative position, while the construction is simple, can be moved relatively far toward the rear and upward so that, on the one hand, a large-surface inflow opening for the cooling air for the cooling of the rear-side air-cooled internal-combustion engine is created and, on the other hand, a spoiler edge for the air flow sweeping over the vehicle is achieved that is situated far to the rear, which results in a good CW-value or drag coefficient value.

An important advantage of this two-part spoiler arrangement 4 is the fact that, in addition to simple kinematics, because of the large shifting path D--viewed in the longitudinal direction of the vehicle--a spoiler edge is achieved which is situated far in the rear with a good CW-value, and when the spoiler arrangement 4 is moved out, the internal-combustion engine is sufficiently supplied with cooling air because a large cooling-air inlet surface is available.

The aerodynamic drag coefficient is low due to the streamlined structure (cda value of 0.19) and the small face area (? 1 m²).

This embodiment is of importance in asmuchas the increasingly sloping windshields of automobiles (lower drag coefficient) present the danger of light-colored dashboards being reflected in the glass and adversely affecting the driver's sight.

It is an objective of the invention to provide an air-guiding arrangement for the cooling of the brakes that is simple with respect to construction and mounting. It is a further object to provide an aerodynamic device that when attached to a vehicle does not increase the drag coefficient of the vehicle.
