It's difficult to see when you can find a reason to use it. How often you going to be in an economy run? Maybe it's more useful on other PDK models. I tried using it a lot on one journey but I have no idea if it really saved that much fuel.
Don’t think that would save fuel as it’s a very short distance where the engine is at tick-over burning a small amount of fuel. In gear on the overrun the engine is burning no fuel whatsoever as the momentum of the car is turning the engine over!! The only way this coasting mode would save fuel is on a long slight decline where the lack of resistance from the engine would allow the car to maintain momentum longer versus the overrun where you would eventually have to use the gas to maintain speed.
I use it mostly going down hills or coming to a stop at red lights. It does move the average mpg on the display up if used but not so much you would notice. Only issue is that you loose engine breaking so if you are going down hill doing it you have to gently ride the break to combat the speed. If you brake too hard it kicks back out and drops a gear bringing the engine revs back. I try my best to use on familiar roads on the commute to help the mpg where i can.
What you have posted is actually a demonstration of “Gliding Mode” not “Coasting Mode”. Coasting mode only works with the cruise control active and actually disengages the transmission allowing the engine to drop to idle while at speed. The 991 did not require cruise control to enable coasting mode so this is a change for the 992. No idea why Porsche changed it.
That’s exactly what does. Disengages to idle revs until it kicks back in. My 718 does exactly the same things. It’s was described as coasting mode in the 992 user manual through the app when I owned the car. That is was how I found out how to do it.
The best I can tell from comments online what you are describing as gliding mode is the same as coasting mode by function. I have no cruise control on my 718 PDK or my my previous 992 PDK. As long as you are not in sport/sport + coasting mode works the same on both cars.
@@Get10YardsHmm. I rewatched your video and you are probably correct. I’ll try it. My 991.2 went into coasting mode by just lifting off of the accelerator, so I thought there might be a problem with the 992. Now it looks like it is working as Porsche designed it. I don’t understand why they added manual intervention to initiate coasting. The only thing I can think of is there are states, Colorado, where coasting is illegal so Porsche made it a manual process. Thanks for the video.

Thanks for the demonstration!
My pleasure!
Didn't know that was there, however, I can't see me using it.
