What is a G5?

Question

I was listening to the song Leavin' by Jesse McCartney, and he says "Girl we'll be flyin' on the G5 G5!" I wasn't sure what a G5 was, because my friend and I were trying to figure out what it was. The closest guess we got was a motorcycle.

Answer 1

G5 is a Pontiac OR the G5 he was talking about was a G5 Airplane.
