GT fuel consumption actually can’t be believed

I can’t believe it myself, but it’s like that.I’m still in the drive-in phase because the GT only has 2400km.Now for this weekend, the cabrio enjoyed and refueled.The tour through the Black Forest was 229km until I was back at my house fuel station.Of course it was a cozy tour, the boardcomputer showed 9.5 ltr./100km consumption on average. So again refueled to compare the average figure, what should I say almost 28 ltr. brought into the tank. h inserting oil in gearbox and engine.I was told nothing at the handover. Anyway, the GT is really fun.
