Unlike the 2014, if you have a 2015, you won't be able to turn it "off." You'll have the option to choose auto (default), stealth, touring, sport, & track. I have mine set to remain in "track."Thanks, I'm gonna have to turn off sound management. I didn't know about that feature.
I've been getting 15mpg in each. I usually drive in the city with lots of stoplights. I've been driving today in ECO mode with sound management off and I've been getting 26mpg. I guess it does make a difference.John, but AFM also works in Sport mode.
What the original poster is saying is that ECO mode (which uses AFM) and Sport mode (which also uses AFM) is resulting in him getting about the same gas mileage. That would make sense if he is driving the car in Sport mode in a manner in which AFM kicks in during most of his drives.
Original poster, how many MPG did you get in ECO mode, and how many MPG did you get in Sports mode? If you are getting 20 in each, you probably should have your car checked. If you are getting 30 in each, it is time to sit back and smile...
Rob, to keep the Govt. off our six, Cafe Regs, Gas Guzzler Tax. The C7 Corvette StingRay is so well rounded, the Govt. is happy, and other manufactures hate it!!I don't know why the engineers even designed this feature . nobody buys a world class sports car for fuel economy.
If one or two mpg is important enough to jerk your engine around between 8 cyl. and 4 cyl., go for it! Do the math and see exactly how much you're saving per year. Not worth it to me.My C7 is a daily driver. I don't see much difference in gas mileage from one mode to another during the week. My gas mileage depends on how aggressive I drive. I did test the gas theory on a trip this weekend. I drove from Miami to Orlando in touring on the way up. I averaged 28.5 miles/gallon. On the way back I used Eco mode and averaged over 30 miles/gallon. Cruise was set at 75mph and in 7th gear. View attachment 13880
