5.7L Hemi MDS VVT vs MDS VVT eTorque

[LeoC4]

What (if any) is the relative difference in reliability between a 2021-2022 5.7L HEMI with MDS VVT and the 2023-current 5.7L HEMI with MDS VVT eTorque engine?

I'm in the process of identifying potential replacement trucks and have decided to purchase a RAM 1500 with the 5.7L engine and 3.92 gearing for a travel trailer (amongst other hauling needs). So far, very few candidates have the 3.92 gearing (most have the standard 3.21 gearing) and none have the 5.7L HEMI without MDS VVT. Any guess why? Is looking for a 2021-2022 without MDS VVT wasted effort?

This has been hashed out in several threads since the first etorque equipped trucks came out. Search the forum for these threads if you have some time to kill.

There are lots of opinions on this. My opinion is to find a 2019 thru 2022 without etorque. Or even a 4th gen or 1500 Classic. I won't own another etorque equipped truck though. Lots of added complexity for very little if any benefit (for me at least).

After 2009 there is no such thing as a non-mds or non-vvt 5.7 Hemi in a 1500,unless it's been modded with a cam that is a non-mds cam,and you lock out the VVT ,which means it'll also be tuned.
MDS and VVT are 2 differant things.MDS is lifter based and VVT is camshaft based.VVT stands for Variable Valve Timing,which means the cam has 38 degrees of movement relative to where the crankshaft is at,while MDS stands for Multi Displacement System,which deactivates 4 cylinders by collasping lifters with oil pressure.Both systems use oil pressure to operate,but they're 2 totally differant systems

I did a search before posting, but didn't see anything which made a direct comparison. Thanks for helping me understand.

Lots of info in these threads. A few users swear by their e-Torque selection, and many semi-technical or technically inclined members swear about them and why to avoid them.

All 5th Gen 5.7L are MDS VVT then? But obviously not all are Etorque.

Yes.The only late model non-mds 5.7's and 6.4's are the ones in the 6 speed Challengers,the early HDs with the 5.7's were non-mds,but i think the last of them was somewhere around 2014. After 2009 all 1500's with the 5.7 are MDS and VVT equipped

Yep, wise words there IMO. I followed that advice to the letter. I recently bought a loaded 2019 Longhorn. I had literally spent months (off and on) looking through all the truck ads online, near and far. At the top of my "don't buy" criteria was the eTorque option. The vast majority ('19 - '22) have eTorque, which eliminated about 90% of the market for me.
