The term drag area derives from aerodynamics, where it is the product of some reference area (such as cross-sectional area, total surface area, or similar) and the drag coefficient. In 2003, Car and Driver magazine adopted this metric as a more intuitive way to compare the aerodynamic efficiency of various automobiles.
Today's hybrids are just now catching up to the best cars from 70-80 years ago in drag coefficient, and cutting aero drag is reponsibile for about 70% of their fuel economy improvement over typical gas cars. Slightly reduced weight and a hybrid powertrain along with use of CVT and smaller engine is the rest. This is embarassing.
This template displays the symbol for coefficient of drag with an optional link to Drag coefficient (link=yes) or Automobile drag coefficient (link=car) and an optional value. If long=yes then the phrase 'drag coefficient of' is added to the front to make it easier to read as part of a full sentence.
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}} .
The drag coefficient of any object comprises the effects of the two basic contributors to fluid dynamic drag: skin friction and form drag. The drag coefficient of a lifting airfoil or hydrofoil also includes the effects of lift-induced drag. [4] [5] The drag coefficient of a complete structure such as an aircraft also includes the effects of ...
The resulting drag coefficient (Cd) factor ranges from 0.32 to 0.35. In October 1982, the turbocharged diesel Fuego became the fastest diesel car in the world, with a top speed of 180 km/h (110 mph). In October 1982, the turbocharged diesel Fuego became the fastest diesel car in the world, with a top speed of 180 km/h (110 mph).
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 C d A , {\displaystyle C_{d}A,} where A {\displaystyle A} is a representative area of the object, and C d {\displaystyle C_{d}} is the drag coefficient ...
Allen Johnson's Mopar Dodge Avenger Pro Stock. Pro stock is a class of drag racing featuring "factory hot rods".The class is often described as "all motor", due to the cars not using any form of forced induction such as turbocharging or supercharging, or other enhancements, like nitrous oxide, along with regulations governing the modifications allowed to the engines and the types of bodies used.
