How to display a child element separately from the parent of a custom taxonomy?

Hello! Please tell me, I have a custom taxonomy "vehicles" group and a 3-level hierarchy.
That is:
Parent > child > great-grandson
These 3-level hierarchies, I've got lots and items I have 377. I'm not sure that explain it correctly and clearly so here is a screenshot for clarity


My task is to bring on the item page, each level of the hierarchy separately.
That is, on the website it should look like this.
Year(Parent) - a list with all the years - separately
Make(Child) - list all of the manufacturers separately
Model(Grandson) - a list with all the models separately

How can I do it? Manually to drive ID do not really want, remember that items 377. What would you recommend?
Yes, I can use
$args = array(
 'title_li' => ",
 'taxonomy' => 'vehicles',
 'depth' => 1


that would be to display "parent" and what "child" and "grandson"? Any help would be appreciated!

It is not clear what you mean by "to display".
But, if you can call wp_list_categories to parent, then what's stopping you to call it with the parameter child_of for posterity?
