My '09 ZO6 with 505 HP averaged 27+ MPG at an average highway speed of 76 MPH on a relatively flat N/S I-95 during my last trip from SE FL to PA. I read an article quoting GM saying the new C7 with 450+ HP should do 28-30 MPG doing legal speeds on the highway.

I am hoping the interior has decent touch points.
I am also looking forward to EPA numbers, these cars could always pull good highway numbers since the Ls1 came around. Now we have less weight, direct injection and better aerodynamics.
Would be cool to see a 450hp Vette nail 26-27mpg highway.
That's incredible from a V8. My '01 C5 Vette with 340 HP used to get 32 MPG in 6th gear on the highway averaging 72 MPH all day long.
BMW really could learn from the GM engineers about how to get high MPG from high output engines.
The C7 will be a bit heavier than the C6.
