Rsq8 fuel economy

[PaulRS7]

Hi guys.
I’ve got a RSQ8 and with over around 3000 miles of driving I’m averaging 20mpg. Mostly interstate driving at 80mph. Not sure if this is what most are getting.
I know it’s a heavy car and does not have a particularly good drag profile, but I’m sure my previous RS7 seemed a lot more efficient.
What mileage are others getting.
Thanks

My RS7 has gotten 25 mpg on highway trips. I'd say I average more like 17 though......... :/
