I've been hearing snarky comments that Porsche is in LMP1 very much as a marketing exercise, because it only sells 30% sportscars nowadays (the rest being SUVs and 4-door GTs) but wants to keep a racing image. If that's the case, and Porsche can pull rabbits out the bag like this HD aero kit, why not keep going?
They might even get some tech development out of this marketing exercise
