On the motorway when I'm coasting down hill I would of thought my car would of added fuel the same as the nominal tickover rate, maybe more if the engine revs are higher.
No, (apparently) the car will know that it can keep the engine going without any fuel (the wheels are moving, the wheels are connected, eventually, to the engine) so it will stop putting any fuel into the engine. So you really are doing ?mpg...until you reach the bottom of the hill.
The engine doesn't try to keep up with the wheels when you're coasting, instead, it lets the wheels push the engine along instead of the other way round.
No hypermilers on STW then?
My E-class is pretty much bang on down to less than 1mpg based on pump fill ups.
Not a million miles off the official figures either with 61mpg on my latest 220 mile motorway trip despite 50 miles of crawling in stand still traffic, 50mpg when careful on my commute up the hills here, through Bristol, up the M32 and then the ring road or 42-46mpg coming back cross country having the odd bit of fun.
I am trying to stop watching the mpg though as I am obsessing about it. I am learning to drive more efficiently though and I seem to be adopting an driving style that will work well when I get an electric car next.

Watt will the MPG equate to when you get a leccy car?
*see watt I did there?*
groan 😉
Mines cock on and yes on a long journey the game is to get as high a fuel efficiency as possible 70mpg being the benchmark.
