Interesting pic from @AUTOSPORT_web that shows what looks to me like a black bag-tank (Not ballast) above the splitter on the @MercedesAMGF1 W09. I'd guess its the auxiliary oil tank, repositioned from the side of the engine as part of slimmer the rear end https://www.as-web.jp/f1/355198/attachment/w09 …
