Is it possible to insert data with a specific id that is unknown while the reference to that id is known?

Example:

I got a car type and I know the name but I don’t know the ID of it.

In the database it known as: FooBarCar 13

Now I want to insert FooBarCar in some reference table but I dont know the id yet. Is it possible to write this into one query/subquery or do I have to select this first in a separate query? If it is possible with one query/subquery can it be done with multiple unknown ‘cars’?

thanks in advance!

    INSERT INTO table_a(`Name`,`cID`,`another_field`) 
VALUES('Something',
(SELECT id FROM table_b tb WHERE tb.cat = '5'),
'somethingelse')
