The two main factors that impact drag are the frontal area of the vehicle and the drag coefficient. The drag coefficient is a unit-less value that denotes how much an object resists movement through a fluid such as water or air. A potential complication of altering a vehicle's aerodynamics is that it may cause the vehicle to get too much lift.
In most high efficiency models or in vehicles with low drag coefficients, a very small grille will already be built into the vehicle's design, eliminating the need for a grille block. The grille in most production vehicles is generally designed to maximize air flow through the radiator where it exits into the engine compartment.
Drag coefficients in fluids with Reynolds number approximately 10 4 [1] [2] Shapes are depicted with the same projected frontal area. In fluid dynamics, the drag coefficient (commonly denoted as: , or ) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water.
The lowest of the three cars' drag coefficient was 0.19, [2] an achievement even by today's standards. For each of the cars, Alfa Romeo provided a five-speed gearbox and a powerful four-cylinder engine that produced more than 90 horsepower (67 kW), good enough to propel the car to a top speed of 125 mph (201 km/h).
The car thus represented a breakthrough in lightweight-yet-strong construction, as well as increasing the power-to-drag ratio, since the lighter, more streamlined body allowed air to flow around it instead of being caught against upright forms such as radiator grilles, headlights and windshields.

The aerodynamics gave the best drag coefficient of any vehicle at the time. [citation needed] On its launch, its main competitors in Europe included the Fiat 128, Ford Escort, Renault 6 and Vauxhall Viva. The GS's aerodynamics enabled the car to make the best of the available power, but when introduced, the car was considered underpowered.
“Over the next 18 months, new car supply will dictate the price of a used vehicle and the best time to buy,” Shaker said. “When new-car supply rises on specific brands, used cars will start ...
