Note, this is similar to this question, but I already know the existence of both words, my issue is I want to know if there is a word that is a superset of both words, another xxx-"dynamic" if you will.
Words like "streamlined" don't appear to work for the context I'm trying to use this in, because streamlined isn't specific to "physical properties that make some object better at moving through a medium than another object of the same class". Streamlined can refer to the cost, number of features or other efficiency related features that don't specifically have to do with efficiency of shape for going through a medium, ie "streamlined process" or "streamlined factory" or "streamlined features".
I'm thinking that colloquially I may be able to appropriately use Aerodynamic to describe both, but I'm not sure if there is a better word.
Situation where this word would be applied:
You switched out the basic chassis with the [hydro/aerodynamic word replacement] chassis on your car, jet, or boat.
