Not sure what mine is, I hope it’s low. The more fuel it burns, the more fun I have.

19.8 MPG based on 24,955 miles and 1,255.9 gallons used.
Highest MPG was 33.0 (best 50 miles) and lowest was 7.1 after a track day. Daily driving yields 19 to 20 MPG.
I use trip A for each fill up and trip B gets reset with each oil change.

I also find the electronic mileage calculation to be a little optimistic.
Based on total miles driven (49137) and actual gallons purchased (2179.071) lifetime average is 22.54 mpg on my '16 Z51, M7
Best mileage calculated for a full tank of gas was 29.5 on one of three cross country road trips
Worst was 8.0 on track at Watkins Glen.
Guess that makes me just another wack job with a spreadsheet.
I never use AFM

Not sure what mine is. I bought the car used last November with 2600 miles on it and the trip meter/avg MPG has been reset at least once. Will have to keep monitoring mine as I drive it more.
At 13.8 mpg, you must be having a hoot driving the car.

I've got 5600 on my car, and my lifetime average is 16 MPG......I'm frankly surprised considering how often I have to gas this car up. It feels more like 10-12. That said, it does really good on the highway...I got 31 MPG on my way back from the Carlisle Corvette show last August.

Just bought my car. When filling up this weekend found that trip B had never been reset. 15918 miles at 21.3mpg. I am guessing previous owner did mostly highway trips in it. I will see if I can’t bring that number down some. Hahaha

I bought my 2019 M7 Stingray from MacMulkin in early February, drove it home to Ohio on Day #1. Mileage reported as 31.5 MPG.
The engineer in me wanted to know the accuracy of the inputs to this calculation, so I charted a course from my home to a friend's house...Google Earth says 28.2 miles....Corvette says 28.3 miles. Good!
Next, I checked reported fuel consumption. So zeroed the "fuel consumed" register on the instrument panel and used about one-half tank. Shell gas station fuel pump says 8.3 gallons, Corvette says 7.9 gallons. 5% error (resulting on the reported MPG on the high side)
Planning to burn a full tank and see if the car is still reporting 5% less than actual. Even so, what this means is my drive home from New Hampshire was actually 30 MPG (instead of 31.5 MPG). I think that is still FANTASTIC! I recently watched a YouTube video with Tadge introducing the car back in 2014, and he reported that it requires only 12 HP to cruise at 65 MPH. Amazing! To put that in perspective, that's half what my ZTR mower uses cutting the grass.

Bought my 19 GS in October and with the crappy winter weather we have had I have only driven it 2,000 miles so far. The overall average is 23.6. Installed the Range Device shortly after purchasing the car so No V4 mode. Spring and Summer are on the horizon so top down driving weather is coming soon.

Purchased my 2018 A8 Stingray with 7 miles on it, 1 year later I’m at 21,250 and it’s getting 21.8 mpg overall. My best 50 mile trip was 36.0. I am NOT easy on her.
Better mileage than the Ford Fusion it replaced!
