DT Acceleration Slow Compared to DS

[Dewey]

I recently traded my 2017 Laramie for a 2023 Limited and the 23 is considerably slower accelerating. Still acceptable, but noticeably slower compared to my 2012 and 2017 Rams. Reminds me of my 03 when the Hemi was rated at 360 HP.

Coming from a 2013 and a 2017 I totally agree with this. Not only seat of the pants feel but also backed up with timers as well. Not to mention my 4th Gens had 6’6” boxes plus toppers on them and being Laramie’s they were heavier than my current Bighorn. Same 3.21 gears on all of them.

Pretty sure this is just throttle voltage mapping.
Gotta love drive by wire! I think these are mapped a little conservatively.

True. If a throttle controller was installed, folks may feel differently

That’s my bet!
These aren’t slow by any stretch, but the tip in pause when you just want to romp on it can be underwhelming for sure

I’m talking more about passing on highways more so than 0-60. Throttle response is not the issue. It downshifts quickly once my foot hits the floor.

It is noticeably slower. After the downshift, 50-70 takes forever compared to my 2017.

As far as weight, my DT is 200# lighter than the DS. I tow a travel trailer occasionally and weigh the truck (with me in it and a full tank of fuel), then the truck and trailer, then the truck and trailer with weight distribution hitch. From my trips to the scales I know the DT is roughly 6100# vs the 6300# DS.

Ahhhh, I see you have a "truck" with 3.21 rears and you ask why it is suggish. I think we see why.

I concur, they're mapped for conservative driving for fuel mileage. I find the first half of the throttle is very conservative, but if you push it progressively further to the floor it ramps up quickly and takes off. Just flooring it does not give the same response as pushing on it more. And if you drive it hard all the time, it learns and adapts over several cycles to give quicker response. If you drive it mild, it learns that too and adjusts.

0-60 times are similar between 2017 and 2022 models with the same engines from what I've read. Seat of the pants results have fooled many people over the years because of throttle control, traction control, suspension design, etc. Use s stopwatch to compare and you'll likely find the newer models are not any slower.

I checked them all by stopwatch and also 0-60 apps. Rolling start they are pretty equal but standing stop the difference is the horrible throttle lag on the 5th Gen even with my Pedal Commander. Seems to be a common complaint. I never experienced that at all with my 2013 or 2017 Hemi’s. Mash the gas and immediate HP to the rear wheels.

Oh well...all I know is mine is pretty bang on for 0-60 times from my reading. I'm also used to the throttle-by-wire system after owning several vehicles prior with similar pedal response. I don't find it all that laggy, but maybe my driving style adapts to it.

There is 100% sometimes an weird delay.
I can't count how many times I almost got t-boned because of it.

Almost feels like a half-a$$d safety feature retarding the throttle when it's first pressed because once you mash on it, it will go. But come to a stop again and it does not respond quickly.

I read that someone replaced his accelerator peddle and it resolved it but I find that hard to believe

Yes, it's called HSL - Heart Stopping Lag. Can't wait for the warranty to be done to get rid of that "safety" feature. I have tried the pedal relearn, but didn't seem to make a difference. I power brake (do the kids call that brake stand?) to pull out in heavy traffic, but the lag is only slightly reduced, and traction control off only helps so much with an open diff and turning.

Even with my Pulsar set to economy, which significantly reduces throttle response off the line, I don't experience this issue you guys are talking about. The only time I have noticed it, and my Promaster City work van is horrible with it as well, is when slowing down for a stop light, or pulling out of a parking lot, where you are slowing down and light changes before you come to a complete stop and you try to get back into he throttle. Then there is a delay as the transmission starts hunting or the correct gear to be in. I've come to expect it from my work van and will manually downshift if I anticipate that scenario happening. It hasn't happened very much with my truck, but I'm sure if I drove it more in city traffic it would

Throttle re-learning helps a little, but after driving it "normally" for a while it goes back to laggy. I just anticipate it. For instance, when overtaking a vehicle, I stomp it down a second or so before I go to make the pass. Kind of sucks, but not the worst thing.

It's not the transmission. If I keep it in gear shifting manually it does the same thing. It's legit like it's retarding the throttle. When you hit it nothing happens, no RPMs nothing for a few moments.
It's done this since I got my 22 before any mods at all were done too.

I feel like it has something to do with etorque and auto start-stop.

Lots of the time when I'm stopped with the systems disabled and I go from auto 1 into manual 1 I will feel a physical clunking and the truck slightly nudge forward (not moving as my foot is on the brake) almost like it wasn't in a mode to accept the accelerator pedals input.

The truck doesn't seem slow, but that delay is going to cause an accident when you think you have 400HP ready to go and your truck sits there for 1-2 seconds before even increasing the RPMs of the engine, it's really scary.

Reminds me of my old Expedition with trans problems. Around 2600-2800 RPMs no matter what you do with the peddle the truck doesn't do anything, like a flat spot on a motor. So you be going through an intersection and then just coast while you want for it to catch up during that time even if you floor the pedal nothing would happen. It was an 20 year old truck with 180k miles on it though, not a brand new Ram.

I disagree with this. I came from a 2003 5.7 HEMI (345HP, not 360). I bought my 2020 and sold my 2003 privately about a month later so I drove the 2 back to back a few times and the 2020 was night and day faster and seemed to do so with much less effort

That's exactly my experience with no throttle improvers. Slowing down for a light or stop sign and not coming to a complete stop seems to confuse the 8spd trans and it doesn't downshift into the correct gear aggressively enough or at all.
I have gear selection turned on and can regularly see the truck starting in 2nd from a light or stop sign if I dont slow to under 3 mph or come to a complete stop. I feel no lag in the throttle at all nor did I on my 2003 which was a complaint back then as well.

Maybe the difference is eTorque… 15,200 miles on the do and this new Ram still doesn’t accelerate like my old truck.

Your disagreement doesn't really mean much since you have never driven any of the trucks I have owned. My 2023 is not nearly as peppy as my 2012 or 2017 hemi Rams and that is just a fact. It's much closer to my 2003 and a factory rating of 345 or 360 is irrelevant.
