How are drag coefficient and frontal area of vehicle related?
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.
What’s the coefficient of drag on an Acura NSX?
Vehicle CdA Make Model Year Cd Frontal Area (ft^2) Acura CL 1997 – 1999 0.34 21.6 Acura CL 2000 – 2003 0.32 22.0 Acura Integra 1994 – 2001 0.32 19.5 Acura NSX 1995 – 2005 0.32 19.2
How does reducing drag affect the top speed of a vehicle?
The reduction of drag in road vehicles has led to increases in the top speed of the vehicle and the vehicle’s fuel efficiency, as well as many other performance characteristics, such as handling and acceleration. The two main factors that impact drag are the frontal area of the vehicle and the drag coefficient.
How does rear spoiler affect coefficient of drag?
Some cars now feature automatically adjustable rear spoilers, so at lower speed the effect on drag is reduced when the benefits of reduced lift are not required. Side mirrors both increase the frontal area of the vehicle and increase the coefficient of drag since they protrude from the side of the vehicle.

How does the front fender affect the drag coefficient?
Front fender skirts have the same effect on reducing drag as the rear wheel skirts, but must be further offset from the body in order to compensate for the tire sticking out from the body of the vehicle as turns are made. The front bumper is the first part of the vehicle that the air must flow around.

How does too much lift affect the drag coefficient?
Too much lift can cause the vehicle to lose road traction which can be very unsafe. Lowering the drag coefficient comes from streamlining the exterior body of the vehicle. Streamlining the body requires assumptions about the surrounding airspeed and characteristic use of the vehicle.

Why does a roof rack increase the drag coefficient?
While roof racks are very useful in carrying extra storage on a vehicle, they also increase the frontal area of the vehicle and increase the drag coefficient. This is because the air flows over the top of the vehicle, following the smooth lines of the hood and windshield, then collides with the roof rack and causes turbulence.
What is the formula for the drag coefficient Cd?
The drag coefficient Cd is equal to the drag D divided by the quantity: density r times reference area A times one half of the velocity V squared.
What’s the MPG on a 2013 Nissan Versa?
New for 2013 Versa sedans with the continuously variable automatic transmission are now rated at an EPA-estimated 40 mpg on the highway, and the different trim levels come with more features. The base S adds a trunk light and the SV gains cloth door trim, chrome door handles and a driver’s-seat armrest.
What kind of engine does the Nissan Versa have?
However, the Versa remains a space-efficient car and can comfortably accommodate adult passengers in the front and rear seats at the same time. Interior features include: The Versa sedan has a 109-horsepower, 1.6-liter four-cylinder engine while the hatchback uses a 122-hp, 1.8-liter four-cylinder.
Is the Nissan Versa top of the line?
The top-level SL adds Nissan’s Intelligent Key, remote trunk release and sun-visor extenders. The Versa hatchback continues to be sold as a 2012 model through the end of the 2012 calendar year.
What is the formula for the coefficient of drag?
Frontal Area formula = Height * Width * .84 (Height and Width in feet) Frontal Area formula = (Height/12) * (Width/12) * .84 (Height and Width in inches) CdA formula = Cd * Frontal Area

What’s the difference between the 2001 and 2002 Toyota Corollas?
Otherwise, the 2002 Corollas are identical to the 2001 models. The 2001 models have better headlights (4-beam), new front and rear styling, new fabrics, and, in some models, map lights on the rear view mirror and dual rear cup-holders with a larger rear center console.
What are the engine changes for a 2003 Toyota Corolla?
U.S. Army Engineer Tan Nguyen wrote: “The 1ZZ-FE (engine) changes for the 2003 Corolla is primarily the larger I.D. throttle body and the switch to the plastic intake manifold shared with the Celica and MR-2 Spyder which has the shorter intake runners.
