Improve Aerodynamics On Cars-
Save fuel

One way of cutting the fuel costs of your car is by improving its aerodynamic properties.
It has been estimated by scientific studies that the energy needed to overcome the various resistances to propulsion is split into the following proportions:-

Air Drag - 60%

Tyre Resistance - 25%

Downward Force - 15%

From the above it can be seen that reducing the air drag of your car could result in a measurable improvement in its fuel efficiency.
Air drag can be reduced by adopting the following improvements:-

• Remove sun roof.
• Close windows.
• Remove roof rack.
• Remove any non-functional wings.
• Replace large antennas with a smaller one.
