I've no huge experience with modern autos in cars, but wouldn't be surprised if that feature had been implemented on cars too. That I imagine would close a lot of the economy gap.
PS if you haven't seen the new whatsthisthen? your expertese could well get the answer straight away.
Interesting you should mention this. I too have noticed that the Aisin tf80 has this feature. However in Lexia this feature is turned off (at least on my car) I've been tempted to turn it on but never have because it may have been disabled for a reason.
But yes the torque converter does drag a lot when stationary as when I manually shift into N the engine stops labouring.
Still I'd wager that the drag from creeping/stationary is much better on the wallet than a EGS destroying a clutch and needing a £2k rebuild or something
