2025 Ram trucks

[nisaacs]

One should be very careful buying from a company who changes/updates their engine every 2 to 3 years to address complaints and issues.

Funny thing is, they didn't update the worst issue of all which has been the roller rocker valvetrain they switched to a few years ago. And they went back to a "revised" version of the problematic CP4 fuel pump. That's not going to sit well with loyalists. OH, and the new engine has OTA update capability....which essentially means they can spy on you and verify any time you tune/modify the engine.

This is an absolute no-go for me. I'll keep my old Powerstroke forever and if it dies I'll buy an old Cummins or another old Powerstroke.

I hope he's paying attention for another pic in about 3k miles. He's getting his moneys worth out of it I'd say.

Looks like I have a long way to go on my Cummins.
A tribute to the longevity of powerful, but low revving straight six engines.

Averaging 58MPH.
That’s movin’…..

Range 1030 miles.
If he has a 50 gallon tank like me, that means 20MPG.

He has the 52+22 gallon tanks. He delivers Gatormade trailers, so he is empty about 1/2 the time. Kinda like RV transporters.

On 11/06/21 his '18 Ram 4500 had this: "Truck is at 398,065 miles and 6,953 drive hours."

Anyone following the new '25 Rams? I like what I see. Some changes noted.
...
3.42 gears only
...

I'll have to admit to skipping a few of the 7 pages of posts, but say it ain't so??? When I bought mine, standard gears were 3.23, 3.55, and 3.92. Of course I ordered the 3.92.

Even with the ZF 8HP trans, the 3.23's and 3.55's feel almost like a CVT, like driving a sack of wet rice.

As tranny gear count climbs, and lower ratios are available right at the tailstock, suppose there's less and less justification for these high-ratio rears. But I still hate the way low-ratio rears feel, no kick in the pants when the tranny shifts, to put that smile on the face of your inner hot-rodder.

Aren’t the Fords and GM diesels still V8’s with turbos? Unless your talking 18 wheelers I’d think they make up a significant amount if the market.

Yes they are I was merely saying that straight six engines are typically long strokes and produce their torque at lower RPMs.

Any engine with a longer stroke tends to produce more torque than a shorter stroke engine.

Hotshot trucker with the 6.7L Ford diesel engine finally had to get a rebuild just prior to 1,000,000 and it wasn't because of the internals. Something else let go. You just don't see this with Cummins 6.7L engines anymore.

True.

Much of the idea in North American minds about inline six having more torque and being more durable than V8, comes from the fact that North American manufacturers offered a heavy duty undersquare inline six next to an economy alternative oversquare V8 for the buyers who used to buy a gas engine in heavy trucks, often with higher rpm no turbo and no cylinder sleeves.

Cummins V903 vs NT855
V504 vs 6CT8.3
Cat 3208 vs 3406

Then there were the heavy duty V engines like Cat 3408 and Cummins V1810 about which nobody ever complained about torque or longevity, because they werent an oversquare economy design..

Krupp in Germany replaced their 2 stroke engines with a license built Cummins V8. They never recovered from that and disappeared from the market.

The short stroke higher rpm V engine trend that America saw in the early 60s never caught in Europe because the heavy truck market was diesel from the start, there were no Hall-Scott or 427 Fords in trucks to be replaced with a cheaper diesel engine option... Turbocharged long strokes started in the mid 50s in Sweden and Holland.

It all depends….
Depending on what other aspects of the design are kept constant.
You could conversely claim, a larger bore tends to produce more torque than a smaller bore, assuming the stroke is kept the same.

There’s no technical reason a V8 can’t have as long a stroke as a straight 6, or that a straight 6 can’t have as large a bore as a v8.
In fact the outgoing 5.7l hemi has a slightly longer stroke than the new hurricane straight 6.
