our car has a peppy throttle response from an already pretty light oem flywheel. unfortunately, the turn off is it is just as peppy at slowing down while coasting. but i havnt really had any issues w/ that personally.

it could also be the tires and wheels or anything else involving rotational mass

So would it be better to coast in neutral ? Im slowing down but trying to keep my speed up as long as possible. I like to coast to a stop sign.

Were your previous cars automatic or manual? Auto's will coast WAY longer than a manual in gear.

Why don't you just keep your foot on the throttle longer and shorten your coasting distance lol

Why do you think that? That's a pretty broad statement and given the dramatic differences between new autos, new autos with locking torque converters, new autos with twin-plate clutches, old autos with stock torque converters and old autos with high-stall converters, why do you think all of these combinations would coast in gear longer than a manual?

why keep it on the throttle when i know im gonna stop? I drive this way to save gas, and save my brakes by not having to brake as hard. I usually drive this way because i am not in a hurry, i like to cruise =D

An automatic has a torque convertor, and will always decouple slightly on deceleration so they coast further/longer. Most don't lock up except when you're on the gas.

Any computer controlled manual (using a clutch, single or double) is still a manual, even if a computer and hydraulics are doing the work for you and will react like one.



Having more effective engine braking takes even more load off the brakes, so I don't see the issue here?

Something that hasn't been touched on yet is that when under engine braking above idle you're actually burning VERY little (or zero) gas, so it's better for economy to stay on the gas a bit longer then coast in gear letting the engine slow you down than to pop it into neutral and coast for longer.
