P&G in gear?

[jayliu1984]

After a lot of reading on BSFC and P&G, it seems that accelerating hard to get to high speed and glide in neutual will save a lot of fuel.

I drove 100% city but would still like to try it, however I find myself have to constantly shift from N to D because a lot of unexpected situations, mainly wrongly timed green lights.

I can rearly archive 55km before I have to start gliding or braking because other cars are doing 50.

So my question is, without changing from D to N, just in gear while gliding, does it still save fuel compare to slow acceleration to 50 and hold it?

So hard acceleration from 50 to 60 and glide for 10 seconds with gear in, VS constant 54?

as for holding your speed at 50 as long as you glide to stops instead of throttling all the way to the light it would be good, but personally when im city driving i hard accelerate from 35-45mph and repeat while staying in gear as some cars coast equally as good in D as they do in N and then gain chances of DFCO

What car are you driving. A GM transmission like Gealii's will basically go to N when you let off the gas. Neutral won't save you much. A Honda like my family Odyssey will engine brake hard. You have to use neutral on that one.
