yes......actually it will go into V4 mode whenever you maintain a set speed for a period of time in Weather, ECO, Tour and Sport. but I'm not sure it will in Track.

Unless there has been a significant change in the newest Corvettes, V4 occurs only in economy mode. Check your manual.

Active Fuel Management feature
As I was driving our new 2016 Stingray home from Bowling Green a couple of weeks ago, I saw the little box on the economy screen with a "V4" in it and I was in Tour mode. Later on, when my dear wife was driving I read though the owner's manual and learned that the engine has an Active Fuel Management System that shuts down 4 cylinders when the engine senses that they are not needed. When we were going up a grade in 8th gear or when we were accelerating, the engine automatically kicked in the inactive 4 cylinders-I began to notice this, too, by feeling something like a shift in gears, but the tranny was staying in the 8th gear. When we cleared the grade or decelerated, the V4 returned.
The manual says that in Eco mode the inactive 4 cylinders are off full-time. At least that is what I understood. Hope this helps. |

I just got a C7 last week, and mine goes onto V4 mode in all modes except Track.
It is a 2016, 2LT, MRC, A8

I think you are correct. My 2015 C7 manual 7 speed only goes into V4 in ECO mode.

The manual cars will only go into V4 in Eco mode. Automatic cars will go into V4 in all modes, including track (per several forum members in other threads), just a lot more often in Eco mode, and very rarely in Track and Weather. The V8-V4 indicator is on the same screen as the instantanious fuel mileage graph.

Hmm, great question but I never get slow enough for it to engage in AFM.

Thanks for the clarification. I drive the manual and should not have assumed Kris has a manual. Cylinder deactivation in all modes except for track is a great feature for the automatic owners.
