Sorry if it's a dupe, didn't find it using search.
Summary: Popular Mechanics drove a manual Z51, 55 mph cruise, upshift at 2200 rpm when needed, they got 37.3 mpg. The C6 that they tested back in 2009 got 32.8 mpg. Not that many of you will do this, but for long interstate drives, this is cool.

I saw that article as we have a subscription to PM.

(of course they did so well 'cause their C7 was Laguna Blue )

They aren't very good at hypermiling then, as there are a few members on here that have done over 40 mpg in their C7s. And I've mentioned it many times before that my best in my C6 has been 37.0 MPG (on a perfectly flat highway, 60mph, with non ethanol gas, for a one hour stretch) I did a one hour drive yesterday and still managed 35.0 MPG even in the pouring rain (which hurts MPG due to more resistance)

I just did 37.5 this past weekend in my C7, also on mostly flat land for more than an hour. Surprised the heck out of me!

Did you go by what the car said or did you do the math yourself?

I read that article earlier this week, and also remember reading its C6 predicessor. Got a good laugh at the writer complaining about having to go so slow in a C7.

I managed to get at best 32 mpg avg on my return trip from Bowling Green... could've gotten better, but, you know... Corvette.

you guys are not having the same kind of fun i am with a corvette.

Patman

You can't always drive 100% throttle everywhere, your license won't last very long!

Seriously though, I am sure it's more fun to hypermile in a Corvette than it would be to drive a Prius at full throttle everywhere

Two words that should never, ever be used together: "hypermiling" and "Corvette."

BigJoe

True hypermiling is one of the most dangerous things you can do with a car on the open road (mainly because all the other drivers on the road get POed and try to get around you at any cost. ). I used to do it on rallies back in the 70s. Got over 40 mpg out of a VW Camper Van! I bet, if taken to extremes, you could get 40-45 mpg or more with a C7 easily.

I have found the car to be within a tenth of doing the math. I didn't set out to hypermile either. Traveling around 65 - 70 mph just turned out 37.5 mpg.

I'm really happy that this car can lead the double life though; it can be an absolutely nasty fast racecar or if I'm going on a long trip can be set with the cruise control and do really well, too! It seems like a real triumph of design and engineering to be able to do both things so incredibly well.

I find I get my best mileage on hilly roads. When going up a hill mileage might go down to 15 or 20 mpg ,but keeping your foot off the gas pedal on the way down nets you 99 mpg. Along time ago I read an article explaining how a car gets far better mileage that way. Better than if you took it out of gear and coasted in idle. Going up to clingmans dome pass in tenn. I was getting about 20 mph in a lower gear and going down the other side a lot of 99's . Would have been all 99's if not for the bad curves. I've forgotten how the cars get that 99 mph but it works.

I don't find that at all in my C6 or in my Civic (which has a Scangauge so I can track MPG accurately) If I'm on a highway trip that is perfectly flat I can easily get 43-45 MPG in my Civic and 35-37 in my C6. If it's a highway with a lot of hills (even minor ones) I won't even come close to those numbers, it will be down by at least 5-10%. And I do let off the gas and coast down those hills too (and will see 100+ MPG on the Civic's Scangauge during those coasts but it's still not enough to overcome the loss of MPG on the uphill portions)
