- The gradual change in colour from
green to yellow to red and back
shows a gentle transition in the
movement of air flow.
- Smooth air flow results in less
drag which translates into using
less fuel.
|
- The flat area above the cab is blue,
meaning no air movement, high pressure
and substantially higher drag.
- The drag of this vehicle is 25% higher
than that of the Aerocell. The drag
increases with rivets, joints
and sharp cornered extrusions.
