The Most Aerodynamic Suspension for a Car

The linkages and arms of a typical car induces a lot of drag. It is just like the strings of the biplane.

The trailing link or arm has the potential to have a more aerodynamic design. Just put all portions of the trailing arm in front of the tyre instead of slightly offset of the tyres.

The video above tells us a lot of tips. He uses his suspension for off-road uses, but some of his tips are most userful.

He recommends that we design our own so that we can adjust the places where we connect the shock absorbers. Not just to buy ready-made suspensions that have pre-determined lengths.

He recommends an aluminum rod for shafts but encased inside a steel pipe. Excellent idea. Aluminium is light and strong but it is soft and difficult to joint together.

He recommends a round pipes for the arms so that they cannot collect mud. A thick bar of aluminium placed vertically should function similarly.

To prevent wobbling, the bar should be reinforced by another link, like most trailing link suspensions that have  joints, but this joint is to the outside, into the direction of the tyre so that it is in front of the tyre. To make it even more aerodynamic, we encase it with an aerodynamic cover, just for the front trainling arm suspensions.

How are the competition solar cars suspended? We cannot see their designs because they are completly covered.
