drag coefficient

[′drag ‚kō·i′fish·ənt]
(fluid mechanics)
A characteristic of a body in a flowing inviscous fluid, equal to the ratio of twice the force on the body in the direction of flow to the product of the density of the fluid, the square of the flow velocity, and the effective cross-sectional area of the body.

drag coefficient

drag coefficient
A typical drag coefficient curve of an airfoil.
i. Nondimensional coefficient equal to total drag divided by ¼ ρ V2S, where ρ is density, V is indicated air speed, and S is surface area of the body.
ii. A coefficient representing the drag on a given airfoil or other body or a coefficient representing a particular element of drag.

In this league, not only has the Audi the lowest drag co-efficient of the four, which certainly makes it the most pleasant to drive, it also feels much stronger.
Aerodynamics are also superior: the drag co-efficient drops from 0.
The monocoque body construction of the EcoSport achieves an impressive drag co-efficient of 0.
Anything with that kind of a coupe-like look has to be good in terms of the aerodynamic drag co-efficient and my thinking is borne by the figures - the XF has a drag coefficient of just 0.
For instance more precise body stamping accuracy has been achieved and this combines with smoother bodywork and underfloor profiling plus flush glazing to achieve a drag co-efficient of 0.
The suspension has also been lowered by Skoda engineers and stiffened to provide a very low drag co-efficient.
Extensive use of ultra-high-tensile steels, an aluminium bonnet, magnesium instrument panel support and plastic side panels have significantly reduced the weight of the new model, whilst the improved aerodynamics have lowered the drag co-efficient to just 0.
The main change is the re-designed bodywork which is claimed to be more drag co-efficient, thus improving fuel economy and lowered noise levels.
Couple that with keeping his gob shut for more than 20 seconds, and that would reduce his drag co-efficient and thereby increase his speed by 20 mph.
