An Audi quattro is four wheel drive, so quattro is 4x4. A quad has 4 wheels, a quarter is 1/4 of a dollar, quattro is 4 in Spanish, etc...
His Yota is four wheel drive also, saying it like that is almost a sarcastic way of saying 4x4...like if you were to say, "is it a two times four or a four times four?"...Ya dig?
and since Quatro is spanish for 4, it works that way as well.
