A kind of ****S (plural)

Please help me!

I see many people answering that "a kind of things" is not correct generally.

Such people say "a kind of thing" or many kinds of things" should be used.

But if I have only one kind ( I mean "a type" ) and I have two or many things,

how can I say?

For example.

"TOYOTA was focusing in hybrid cars and succeeded in developing Prius"
"TOYOTA planed to make 10,000 Prius per year"

In this case, can I say like the following or not?
"TOYOTA planed to make this kind of cars by 10000 per year"

thanks
