26+ logged miles with a average speed of 70mph... I think that's a fair piece of sample data. Either way, this is crazy

This is no surprise to me. I'm guessing many will average 35-38 mpg on the hwy over long trips and will hit 40+ if they are really workin at it.

This is how I'm going to sell the idea of trading in my Camry Hybrid to my wife!

Well, he did it for 26 miles. It doesn't prove much other than the car be pretty efficient at times.

I don't see why not.

I pulled 31-32 mpg in a 100k mile 96 LT4 averaging 70-72mph over a 400mile trip.

You should have seen the gas mileage my C6 Z06 got while I was driving the 19 miles down Pikes peak. Unbelievable. But I didn't average 70 MPH doing it.

I've found my DIC reads about 1.5 MPG higher than hand calculated number.

Well, if you think about it, it's not that unreasonable to get this kind of mileage under the right conditions

In Eco mode, its basically a 4 cylinder car. And, it's running in a very tall 7th gear. And, it's pretty aerodynamic. And, it's not a heavy car like an SUV.

I can see these kinds of numbers on a level surface at the correct speed.

Can you imagine the money GM must have spent to get Autoweek to post that picture?

I can believe it as I got 32.8 MPG in my C6 at 65mph, on a 2 hour highway trip with the windows down for part of the trip and the AC on for part of it, and I don't have the extra benefit of cylinder shutdown technology or the taller 7th gear. I've figured all along that the C7 should easily get way better gas mileage than the C6.

Based on my observations with my OVERPOWERED LS7 with it's HORRIBLE aerodynamics, and WIDE tires, 39-40 MPG under good conditions is achievable with the C7.

Cruising at 70 MPH on level terrain, with no winds, no A/C on, I can rack up 30-31 MPG(hand calculated, not DIC readings) without breaking a sweat. Driving across Kansas in the very early AM, on I-70 at 80 MPH, no A/C, no wind and 70 degree ambient, my DIC will show 33-34 MPG(my DIC reads around 1.5 MPG high when checked against my hand calculated numbers).

Keith notice the trip was only 26 miles, let's see those numbers for 350-400 miles.
