I've had the 6.2 in another vehicle before and it's great, but really interested in the ecodiesel. Never driven a diesel before. I drive on a lot of rural one lane highways in texas with high speed limits and sometimes you have very short distances to pass people. With the lower horsepower on the diesel how is passing power? I know you can't floor it and expect it to go like the 6.2, but is the acceleration still pretty good at higher speeds?

I just picked mine up this week and took it on a 500+ mile road trip straight off the dealer lot. Lots of two lane roads on the drive and it never lacked power to pass anyone. The torque and 10-speed transmission made it great to drive and pass. Not to mention the 22mpg for the total trip.

Had mine since last Nov. Im in south Tx where it’s sorta the same with a lot of 2 lane roads and this was my first diesel as well. It has plenty of passing power. I came from driving the 3.5L ecoboost ford. The ford was like a rocket. In the diesel, I tend to go slower at lower speeds but when I need to get on it, this thing moves.
and you can’t beat the mileage. Avg is 20 to 21. Highway speeds 75-80 is normally 24.5ish

Im glad I came across this thread. Still waiting on my truck. This will be my first diesel as well and was wondering about passing power.

I wonder how the LZO will do with the added HP

I picked up a 2022 AT4 with the diesel on Monday of last week. and it has plenty of passing power. There might be some lag from the pedal to the actual throttle response but it is not terrible. Im sure the LZO will only be a better feel with the added HP

The 3.0L diesel makes as much torque as the 6.2L gas - if you are having trouble passing, it isn't the engine...

I found it to be close to my old 5.3l. Maybe the 5.3l is a bit faster on the very top end but by the time it downshifts to get into the torque band, I would call it a tie.
There are YT videos of the 5.3 drag racing the 3.0 diesel. The 3.0 is quicker and wins in those head to heads.
I traded my 3.0 AT4 two weeks ago an d now have a 6.2 2023 AT4X. The power of the 3.0 diesel is great. The transmission shifts so well and smooth to utilize it's torque. The 3.0 won't out run a 6.2, but it is not a dog at all. Loved the engine, torque, MPG and overall power. Never a problem passing or otherwise. Now the 6.2 is faster of course, and I haven't put a lot of miles on it, but really the 3.0 was a great engine. I only traded that 2020 AT4 with the 3.0 diesel because they couldn't figure out how to fix the multiple "servce emissions system" warnings on the dash. After a month of being unable to use my truck and being stranded out of state because that warning code puts you in super limp mode making it impossible to drive very far, I traded it off.
I know the DEF and emissions systems in these newer diesels these days can be finicky. I never had a single problem with my engine up until this mystery "service emissions system" dash warning, and don't think there was anything mechanically wrong with it to be honest. But the many different and complicated sensor systems these trucks have now are a mine field it seems, moreso on diesels.
I agree with you on all the sensors. I wish I could delete them. So far I have 25k miles and haven’t had the first issue w my 2021 at4 lm2. I love it. We just drive from Corpus to Ruidoso NM and back. NM mileage at 67 mph was 37mpg and then coming back to Texas I jumped to 80 mph my mpg dropped to 24 mpg. So far so good
I never had an issue until 39K miles with all these sensor problems. I did have a few times the DEF level sensor was "stuck" or something. Like it would say the DEF level was full or almost full, then it would suddenly drop to empty giving the limp mode warning.
As far as the 3.0 engine, great power, super smooth to drive with that excellent 10 speed tranny mated to the torquey 3.0 engine. Lots of pulling power. Great fuel mileage. Just a really good engine, but all those complicated sensors it has add risk to hard to diagnose/fix problems happening. Glad you have had no problems so far!
Same exact issue you described with the DEF gauge being “stuck”. Each time it’s happened it’s been when I’ve parked on a slope.
Living in the mountains in Montana, I am on steep slopes fairly often. My wife still has a 2020 AT4 Carbon pro, and hers does it some yet too. The issues I had on my 2020 AT4 diesel has us concerned hers may have similar issues soon. Hers has 27K miles on it. No issues with hers yet, except for the same intermittent issues with the DEF guage levels just dropping. Like the DEF guage just gets stuck. I never had a problem putting DEF in, it's not a big deal, but I did take my truck in to the dealership a couple times for this and they never had an answer or figured anything out.
I am not sure mileage has anything to do with it. I’ve only got 17K on my 2021, and the first time it happened I was at 9500mi. I’ll bet it has something to do with the float. (If they still use those - lol)
