In fact Ford uses...I believe...a version of the Cummins B series 6 cylinder diesel in their largest truck, the medium duty F 650.
The Cummins B series 6 cylinder diesel is the same family of diesels, just another version that is used in the Dodge pickup.
I've often wondered why Ford never used a version of their own power stroke diesel in their medium duty F 650.
GM, before they shut down their medium duty line of trucks, the 4500/5500 series.... used a version of the Duramax diesel, which of course is also used in the GM pickup line.
Good questions, since until recently the Powerstroke was International-sourced, and IHC used those engines in trucks comparable in size to the F650/750, as well as school bus applications.
I intended to mention that...but I forgot. I'm getting old. LOL.
Thanks for mentioning. This fact brings up another question. Why does not Ford use their Ford designed diesel power stroke in the medium duty F 650 ? I can't see why Ford wouldn't use their in house V8 diesel...in suitable hp/torque tune in a MDT truck...like the F 650.
As far as GM, the 4500/5500 were in the same GVWR class as the Ford F450/550, which did use the pickup truck drivetrains. The Kodiak 6500/7500 did not use the V8 Duramax, although some versions did use the 8.1 gas engine.
If I recall that was the case. I think also the GM MDT's had as options a Isuzu I6 diesel and a Caterpillar I6 diesel. Both were around the 7 liter + displacement if memory serves.
Now that I think of it, the F 650 has as an option the 6.8 liter gas V10...or did.- Nice Ford infomercial from their truck communications manager. I see Mike has joined the Forum. Tell me Mike how can someone take your reviews seriously if you are on Ford's payroll :h :@
It was reported by another member you left PT.COM (not Ford) but you posted "Hello all. This was a Ford conducted test with the most capable trucks available from GM and Ram. GM was a 3.73 because that's the shortest axle available. If they had a 4.10 or 4.30, we would have tested that"
Mike joined Ford Motor Company in 2011 as Truck Communications Manager.

Note: that I do agree that the Ford and GM having V-8 diesels will out preform the in-line diesel in a drag race, not sure why that would matter. However the in-line will last much longer and have lower maintenance cost. Also what transmission was in the Ram and GM
Chrysler's infomercial Ram wins, as expected. Their test their truck wins. Means nothing at all.
Mike could you explain why your magazine is testing a 2014 F-450 against a 2014 Ram 3500? Would a head to head test with a F-350 be a better test?

And Ram is doing it with 20% fewer cylinders. What would it be like if Cummins was a V8?
And the Ford will most likely get the better fuel economy just like today.Lessmore wrote:

Those I6 motors were in the "real" MDTs-6500 and up. Ford does offer a V10 in the F650.- I wonder if that was the 370hp/800tq 68RFE Cummins powertrain in the Ram, or the 385hp/850tq 69ASC version? That would make a difference in the performance.
- My unsolicited $0.02:
1) Other than those with an unhealthy obsession, who cares about a few seconds either way? There's no convincing me that any of the Big 3 is (key word here) significantly better performing or more reliable than the other 2.
2) The "what if" game (discussing # of cylinders or rear end ratio) can be played to infiniti; what if a GM 8.1, Ford V10, or Ram Hemi was turboed or supercharged? What if Aunt Sally was born Uncle Sal?
3) Not sure there really is much "unbiased" testing these days; ad dollars and closed-door handshakes have to be at least considered as possible influences.
I enjoy these tests/comparisons for what they are, but I take them with a grain of salt.
I enjoy not being brand loyal...it's liberating.
PS- Not to split hairs here, but the ISB that goes into class 6 & 7 trucks is not identical to the ISB in Ram pickups. They are brothers, but not twins. itguy08 wrote:

Don't you think they would have included that as a test in their commercial if it were true?Perrysburg Dodgeboy wrote:

You can make your own decision about. the video. I'm explaining how we grouped and tested the trucks.ib516 wrote:

We tested the Aisin.- I have no trouble believing the test results. Looks like they had fun, nothing broke or melted and they all made it to the top within a short time of each other. Good for all three.
