Hope to compare behavior of my '14 2.0L FWD to yours.

The information display cluster includes an option for instant fuel economy. Per the owner's guide "Instantaneous Fuel Economy: This display shows a visual graph of your instantaneous fuel economy."

I get no graph. Only the average economy since last reset. Nothing instantaneous about it. Took it to the dealership last week and the "expert" walked me through the settings only to conclude that my vehicle didn't include that option. Trip 1 and Trip 2 work as expected.

If any of you could shed some light on how your vehicle handles this, it would be appreciated. I like the gadgets a lot and feel that this is too simple a function to not be included.

Drove the larger MKS while my car was in for service and the instant fuel economy works as expected on that model. Wishing one of the 256 viewers of this thread might comment on whether or not their MKZ really works as advertised (meaning pressing hard on gas pedal causes instantaneous full economy gauge to drop and coasting makes it jump up).
