This question applies to cars with automatic transmissions only. I've read in multiple places that "modern" cars will shut off the fuel injectors when you lift off the gas, allowing you to coast/engine brake to a stop while in gear without using any fuel. So if you were braking to a stop in front of a red it would be better to stay in Drive instead of idling in neutral like you might in a manual.

Of course for most of you that's common knowledge. My question is, what do they mean by MODERN cars? As in, anything past 1985 modern? Or like, 2013+ model year BMWs and high-end cars that have engine stop/start and that kind of stuff? How would you know if a given car had the injector shutoff feature? Would it say in the manual? Could you listen for it? For the record I'm trying to teach someone how to drive a late-90's Nissan Maxima (A32) for better MPGs and I need to know which technique would be better.
