Mine doesn't turn off when i move the shifter to dynamic?

 

Right, on my 16 only the button turns it off, not dynamic, not sport.

On my 14 V8S it turns off Eco

 

When you say moving the shifter into dynamic - moving the shifter puts it into sport. You engage dynamic via the rocker switch - is that what you mean?

Engaging dynamic disables eco on my 14 V8S

 

Engaging dynamic does not turn off eco for MY 16

 

I think it's a 2016 thing. I have a 2016 Range Rover Sport with the V8 engine and I have to turn off eco mode to turn it off. In the 2015 RRS I test drove putting it into dynamic would turn off the eco mode.
I suspect they did the same with both brands.

 

Yes, exactly. On 14-15's Eco mode was disabled in Dynamic mode. That changed for '16. Because of continued fuel economy mandates, in a couple of years or so there won't be any way to disable it from inside the car.

As I've said here a couple of times before, I'm surprised that the US and EU still allow manufacturers to get away w/ a button to turn it off because the vehicle mileage certification is established w/ start-stop operating.
