S Mode and mileage difference on/off

But but but what IF say you're cruising on 5th and prepare to stop at a red light. Instead of downshifting you put it in neutral and just use the brakes to slow down? That would save you gas right?

yea in theory it would save gas. because less throttle/gas blipped. Actually, I've done some experiments myself, if I consistently heel toe and downshift vs popping it in neutral, over the course of ~18 gallons of tank u got you will see somewhat noticeable mileage difference maybe ~25 miles or so. but it all depends on how much you're doing it

This. When driving I pop it in neutral and downshift to whatever gear needed when it comes time to accelerate out, whether it be a turn or a red light turning green, with s mode on it continuously revs to match speed.
I find it strange how yes I admit it may be a little bit, but someone brings up a good topic and people just can't believe that were discussing it, if you don't like the topic or think it's ridiculous in anyway why post a response to begin with?

We can talk about this

NO! When you are off the throttle IN a gear you are using almost no fuel. Coasting actually works the engine like a generator. When you are in neutral and braking the engine will just be idling as if you are stopped.

That's what I do if I know I'm going to have to come to a complete stop, go to Neutral after slowing down to 1500rpm or so in whichever gear I happen to be in. If I won't have to stop just leave it in gear, maybe downshift once or twice. Putting it in Neutral does use MORE gas than leaving it in gear and not braking even if you are at 4000rpm.

Sorry, but your results are going to be almost exclusively from different conditions. You may not realize it but you probably drive more aggressively with it on. S-mode alone is not going to add or remove 25 miles per tank....are you guys nuts?
