teardrop
Q. What happens to drag when speed increases?
With an increase in speed comes an increase in drag and a decrease in net force. This decrease in net force reduces acceleration.

Q. What is the perfect aerodynamic shape?
For speeds lower than the speed of sound, the most aerodynamically efficient shape is the teardrop. The teardrop has a rounded nose that tapers as it moves backward, forming a narrow, yet rounded tail, which gradually brings the air around the object back together instead of creating eddy currents.
Q. What is the most aerodynamic car ever?
ARVW concept car
Q. What is the most aerodynamic muscle car?
Volkswagen XL1
Q. What car has the most downforce?
Mercedes-AMG Project One
Q. What is the most aerodynamic shape for a CO2 car?
Sphere
Q. What makes a CO2 car go fast?
Aerodynamics, thrust-to-weight ratio, surface drag, rolling resistance and friction–all play a role in what makes a CO2 car fast or slow.
Q. How fast can a CO2 dragster go?
around 90 kilometers per hour
Q. How do you reduce drag on a CO2 car?
Because the dragster has parts moving against one another, friction is created. You can help reduce it by making sure the axles are free to rotate, and that the wheels and tires are not rubbing on the car body.
Q. What keeps the dragsters from flying off the track?
They are frequently used to demonstrate mechanical principles such as mass, force, acceleration, or aerodynamics. Two hooks (eyelets or screw eyes) linked to a string (usually monofilament fishing line) on the bottom of the car prevent the vehicle from losing control during launch.
Q. Why do designers try to Minimise drag?
As the car will have smaller forces acting against the car’s movement, it will be able to transfer more of that power produced by the engine into movement, remembering drag increases with the square of speed, reducing a car’s drag coefficient results in much higher speeds.
Q. Why do drag cars use CO2?
CO2 puts the pressure on the wastegate to hold the valve closed as soon as or before it is actually needed. It reduces SO MUCH time when trying to build boost or spool a turbo engine.
Q. Can you use CO2 as nitrous?
CO2 contains more O2 than atmosphere so when you inject it into the engine you will get a SLIGHT bump in power but nothing like you would with nitrous which is 4X’s the useable oxygen. CO2 injection into the engine won’t really do much unless you’re running a lot of hot boost and just want to cool it off a bit.
