Yes,very much so.It's the plan-view corollary to the side elevation effective fineness ratio.
Kamm and Koenig-Fachsenfeld devoted quite a bit of wind tunnel model studies to quantify the effects of the L/WXH ratio for both Jaray-form,and K-form car bodies.
How the body cross-section varies along the longitudinal axis,to and from the position of maximum cross-section is critical also.
Fast pelagic fish are a good model for streamlining.Their frontal area occurs in the first 1/3rd of their body length and the last 2/3rds cleans up the disturbance.
