2022 CT4-V Blackwing 46-404
What are y'all seeing and which car do you have

Mine is a manual CT4V BW, a little over 17k miles on the car, lifetime mileage is 16.45 mpg.
 
4BW 6 speed with 3k miles getting about 22 mpg. Mostly highway driving
 
My 4BW is averaging around 14-15 city w 6k miles and I drive it like a grandpa. The LF4 has always been pretty bad on gas.
 
My boss says if I'm getting good gas mileage I'm using it wrong.

I have been averaging 17 according to the gauges. Mix of stop & go, short suburb driving, and highway. CT5 V Blackwing 6M. Not bad considering the capabilities.
 
I'm getting under 15 in city/stop and go highway driving in my 4BW. The rare times I drive a substantial distance on the highway outside of rush hour it ends up around 22.
 
According to my logs, about 19.7 MPG in my A10 4BW through ~4100 miles. They're mainly highway miles.
 
I'm getting 16.4mpg lifetime at 2,000 miles in my manual 5BW. About an even mix city/highway. Basically the same as my E39 M5 and E90 M3 - not bad considering it is heavier than both and has more than twice the torque of the M3.
 
18.4mpg average over 4400 miles on my 4BW
 
I doubt anyone bought this car for its gas mileage. Its a high performance track car !
 
5 w/ manual - i get 13-14 in the city (avg ~30 mph).

Real highway mileage is 20-21. Amazing how efficient it is on the open road.
 
15K miles on my 4BW 10A, I see ~21mpg average commuting 127mi/day with 40m of that being canyon road from sea level to 4,000' elevation. Best I have seen is 25mpg on a road trip to NV.
 
I never really thought to look. I have never made a vehicle purchase for gas mileage or even really thought about it, just one of the things you deal with to have what you want. But hey, I'm here and will join in. Surprisingly this gets the best gas mileage of my cars LOL.. Here you go 22 CT5BW=16 average 2400 miles, 2000 svt lightning=11 average over 5k miles, 07 Z06 (just sold, but not picked up yet) 14 average over 1k miles. Z06 is HCI 600rwhp, think it could do quite a bit better but I just can't help myself...

The additional 4700 mi was maybe slightly better (12-13ish) before I mistakenly reset the trip computer

The best way I've found to get lifetime mileage, if you're interested in doing so, is to scroll up to the screen where it shows you how many gallons have been used and then just divide total mileage by total gallons used.

10758÷828.6= 12.98mpg
... looks like I'm trending down😈
I must have been babying it too much early on😉

21 mph avg speed....... :(

I'm so sorry you're forced to take this beast through such tortuous conditions.

I thought my commute was bad when I avg around 30 mph. Mpg is very tightly correlated to average mph.
