G55 – The hammer if not consumption

hi, in the end it doesn’t matter, but I have to get rid of it. a G55 has overtaken me on the A3. that one G is faster than another, this is already a rareness. but the sound that the G has given itself: woww. what will he have consumed at a speed of 200????? at 210 he probably regulates. how far will he come at full gas?????
