20 point something... Happy to get that. Every light is an NHRA tree.

gsflyer2011

11 M6 GS and my DIC reads average 13.3 MPG. I have not reset it in the 5 years that I have owned it. Now that is what I call driving like bat out of hell. The mileage I get out of it is totaly no concern for me. It is the price of the fun.

Turn and burn baby!

ROJ#79

I get between 22 to 23 MPG. On my '08

Sabre34

I have never checked.

BillytheKidder

20.3 over the last 156 miles, according to my dash; about 70% highway, the rest tear-assing around making some Saudi Shiek rich.

Being an OCD engineer, I've kept mpg record for the 8 years I have owned the C6. Lowest mpg was 16, highest was 32. Average over 55k miles currently on car is 22.8.

2012 GS auto, average 24.6 or thereabouts on my daily commute. Round trip is about 54 miles, roughly 90% highway and 10% surface streets with traffic lights. I go in early so no traffic but the trip home invariably has pretty heavy traffic.

LowRyter

low-mid 20s seems to be the norm.

Jmhornz71

Most of fillups I check and its around 21mpg that is about 80%city, Just took a 1350 mile trip which was alot of hgwy with some city the overall mileage was 27.8. I dont drive for the gas mileage as I like the go pedal to much but its nice

Vette_DD

27 MPG to 28 MPG on the interstate at 75 MPH. 20 MPG overall when I was still driving on both interstate and some in town. 15 MPG now, all in town. 2012 coupe w NPP exhaust open all the time.

Vet Interested

Last road trip 2 months ago from San Diego to Talladega to Bowling Green to Charlotte and back to San Diego, I got over 25. That includes flying across Texas, Arizona and New Mexico. One thing I noticed. The car lies (a little). I have an app that figures out MPG on my phone to the mile and the car was always just under .4 MPG high.

C6 Snowboarder

Both my Grandsports M6 -- are about the same on the DIC.

duckvett

`10 GS convertible A6 - just returned from a 4500+ mile road trip, avg. speed 58.2, avg. MPG 25.9. Nearly all the freeway driving we did was at 75-80, mountain driving (Beartooth Hwy, Custer State Park, Rocky Mtn Nat'l Park) was 35-40. Just my opinion that these cars get better mileage at 80 than 55-65.

CadVette

15 to 16 on my 07. Never more than 16 even with a 5 hour drive. Guess I need lighter shoes.

pagosawingnut

My '08 averages 26.7. If I keep it under 65, it averages 34 mpg and when I get on the interstate, it drops considerably.

WW7

..You must drive it like you stole it all the time..The worst I've ever seen on my base model is 21 mpg in the city and I get 28-30 mpg highway...WW

'13 GS coupe, I get 26 highway @ 80 mph but daily driving to work and around town only 14 to 15. Tear assing through the mountains is less. I reset it every fill up.
