The Chevrolet Corvette (C6) is the sixth generation of the Corvette sports car that was produced by Chevrolet division of General Motors for the 2005 to 2013 model years. It is the first Corvette with exposed headlamps (as opposed to hidden headlamps) since the 1962 model. Production variants include the Z06, ZR1, Grand Sport, and 427 Convertible.
Drag is a force that acts parallel to and in the same direction as the airflow. The drag coefficient of an automobile measures the way the automobile passes through the surrounding air. When automobile companies design a new vehicle they take into consideration the automobile drag coefficient in addition to the other performance characteristics ...
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.
is the drag coefficient – a dimensionless coefficient related to the object's geometry and taking into account both skin friction and form drag. If the fluid is a liquid, c d {\displaystyle c_{\rm {d}}} depends on the Reynolds number ; if the fluid is a gas, c d {\displaystyle c_{\rm {d}}} depends on both the Reynolds number and the Mach number .
[1] [2] Informally, it is the sum of the loads resulting from aerodynamic drag, acceleration, rolling resistance, and hill climbing, all divided by the mass of the vehicle. [1] Conventionally, it is reported in kilowatts per tonne , [ 1 ] the instantaneous power demand of the vehicle divided by its mass. [ 2 ]
C6.R GT1 (Z06) In 2005, the factory Corvette Team began racing the C6.R to coincide with the new sixth-generation (C6) Corvette being released to the public. Private teams, primarily in Europe, continued to race the C5-R for a couple of years before switching to the C6.R. Corvette C6.R went on to win its class at every race it entered in the ...
A drag count is a dimensionless unit used by aerospace engineers. 1 drag count is equal to a of 0.0001. [ 1 ] [ 2 ] As the drag forces present on automotive vehicles are smaller than for aircraft, 1 drag count is commonly referred to as 0.0001 of C d {\displaystyle C_{d}} .
In mechanics and aerodynamics, the drag area of an object represents the effective size of the object as it is "seen" by the fluid flow around it. The drag area is usually expressed as a product , where is a representative area of the object, and is the drag coefficient, which represents what shape it has and how streamlined it is.
