Question On Start Stop Engines

[Cudapower]

On new 2021 Ram 1500's does the regular Hemi now have the stupid stop start function or is that still just on the V6 and electric boost models?

As far as I know it’s still just the V6 and ETorque Hemis .

Easily solved with https://www.autostopeliminator.com/. Not paid advert... simply happy with it. Auto start stop is annoying as all get out if temps are cold or hot as it stop, then jerks to a start while your sitting there. I did the 5 min install and it works perfect. I leave stop/start disabled in all but mild weather where my AC/Heat isn't working hard. I wouldn't let that guide my choice as to eTorque or not. If you ever want to do any engine mods, skip eTorque. On the other hand, I do find it smooths out off the line starts and shifts.

I purchased the Tazer DT which remembers the last state of the auto start stop button. I dont mind it most of the time, but disable it in the summer as theres a funky smell when the ac kicks on after being off for a bit.

The only hemis with start stop are the etorque versions... the electric motor that is the etorque is the starting motor for auto start setup.

Thanks for the input everyone.

I think it’s stupid as well, but to my surprise it’s not as noticeable in my rig as other vehicles I’ve been in. Pretty smooth actually.

Agreed, they did a remarkable job with the setup in these. Drove a 2021 grand Cherokee in vegas a few weeks ago while on vacation and it’s system was very noticeable compared to the one in my truck.

Love my etorque. I barely even notice it at this point. Smoothest stop start system I’ve ever driven.

I was just in my buddy’s brand new 2021 GMC Sierra 1500 that has it and wow what a difference from the Ram. It was pretty harsh and he was already complaining about it.

I have grown used to it and do not mind it at all now.

The only caution is brake pedal pressure when at a traffic light or stop. I was a “light“ brake holder putting as little pressure as possible and sometimes letting my vehicle creep forward at a stop by modulating the brake lightly (often making those awesome creeking brake sounds with my previous suburban, plus it irked the wife...lol). I did not know or really notice this habit until having my Ram with auto start/stop in the first few days of driving.

If it shuts down at a traffic light and restarts due to AC or heating needs, it can lurch (1/2 wheel rotation) forward (what e-torque is designed to do) and override a very light brake hold, moving you forward that Distance. Fortunately I tend to leave more that 1/2 a wheel turn between me and the car in front of me.

I do not even notice it now at all.

One Other caution. The Hemi is so smooth and quiet at a idle, I sometimes do not notice if it’s running or not due to Auto start/stop. There is no vibration and the tach can be the only indicator. This is the smoothest engine at idle I have owned (Next to my EV) and I am amazed it’s in my Ram truck.

At least twice I have been stopped, not realizing the motor is off and been highly startled at “Zero“ oil pressure.....thinking I had a major problem (Did I tighten that oil filter...lol). Even to the point of almost announcing it in the car, only to realize it’s not running.........Hopefully I get past that.
