I think all this delusion of weight saving is senseless. Since the developers forget that there is also wind from the side. I once had a Sierra. It moved at 180 km/h by one meter. With the wind of the last days I noticed that the high Phaeton weight brings considerable advantages. When I saw the jingling vehicles, became quite different to me. My Phaeton stubbornly pulled its track with at least, partly 180 km/h. peso
