Hi everyone!

I just get my new Honda Accord Coupe, with 5-speed automatic transmission.

Every time I fully release the gal pedal, I feel kind of sudden deceleration. I used to drive a Chevy and a few other rental cars, I don't remember feeling such obvious deceleration when releasing the gas pedal.

Is it because this is a new car? Will it disappear after break-in? Or there is something wrong?

Your old Chevy had the turbo hydramatic 4 speed automatic, and that transmission has an insanely long overdrive ratio. So when you release the gas on pretty much any GM car when it's in overdrive, it will not decelerate very quickly, just keep on cruising. That's why they typically have horrible throttle response.

Hondas have a much shorter gear ratio, even with the 5 speed. Your throttle response is normal, and actually, it's how a car SHOULD be engineered.
 
If you're not applying gas you shouldn't keep going full speed. As mentioned by fastball it helps with the throttle response, but what if you became incapacitated in some way? Would **** for the crowd you hit either way, but much less if it didn't maintain speed without pedal depression. I'm amazed that some cars will keep revving!

I know the deceleration feeling you are describing here. I believe the reason is when you release the gas on the Accord, it shuts off the spark plugs and fuel injection completely so no excess fuel is being burnt. This causes a more dramatic speed reduction than compared to the GM vehicles you are referring to.

Correct me if I'm wrong on this, I don't know for sure.
 
Maybe that feeling when the engine mountings are bad ?
 
It is hard to understand what you are describing by "sudden decel." By large, this is normal for this car. If you keep of the gas pedal and as your speed decreases, it will downshift as well. If you feel that the slow down is equivalent to applying the brakes, take the car in and ask for the dealer to take a look.

Great explanation!

Have the same exact issue! But as everyone said, it's normal but I find it quite annoying. I've learned to speed and tail people moreso because if I let go of the gas I get that annoying decel.
The car does drive different than others in this regard, but you could hold a steady speed rather than taking your foot off completely. I've never heard of anyone engaging in offensive driving habits as a way to drive this car.

Of course I also try to hold a stead speed but it's quite hard in stop and go traffic.
 
Again folks, it has nothing to do with the fuel cutoff (all gasoline, ICE engines cut off the fuel when you release the accelerator.... even your old fashioned carbureted and manual choke cars).

Nor does it have to do with whether it's front wheel drive or rear wheel drive: BMWs have amazing throttle response, they've built their reputation on it.

It is a normal part of the driving dynamics of Hondas, and it's been like this with every Honda I can remember driving or riding in, and it's been a few over the last 20 years. Both automatic and manuals.

Honda manuals and autos use a final drive ratio with around a 4.7:1 while the turbo-hydromatic 4 speed has a final drive around 3.11:1 . This is for a couple reasons: first it enables their high reving engines to stay within the sweet spot of the power output more effectively, and also enhances throttle response.

The reason GM and other manufacturers use tall OD ratios is to improve fuel economy. Check the fuel economy on an old GM 3800 with the T460E. It probably says something like 18 city/31 highway. You'll notice many GM cars running at 70 mph at barely over 1000 RPM. That's nice for freeway cruising, but ****s if you need to pass. If you have a stick you'll need to throw it down to third gear, and if you have an automatic you need to punch the pedal to the floor to kick that transmission out of OD.

And obviously, slowing down with such a wide gear ratio forces you to use the brakes more often thus why American cars typically run through front brakes faster than Japanese cars. I know each set of my Prelude brakes lasted 70k miles. Engine braking is a wonderful thing, and you don't need to downshift to use it. A properly engineered car will decelerate when you release the throttle no matter what gear it's in.

Thanks for your explanation, that makes complete sense.
