This is exactly the case with bi vs twinturbo, some manufacturers call it biturbo others twinturbo, even tho they can be using the same setup.

A twin turbo has two turbos at the same size, but a bi-turbo has 2 different sized turbos. and the audi quattro is called an awd over here in europe. 4wd can be overridden, whereas awd is all 4 wheels controlled by a computer. in subarus and audis most of the power is sent to the back/
