I think it's pretty tough to argue that any one of these new diesels is more dependable than the others and this thread is actually supposed to be about how Ram/Cummins is not even in the same league as Ford when it comes to efficiency. If Cummins isn't concerned about keeping up, Ram might have to try to negotiate a deal with Ford to supply them with engines.

That is if you go off of test like these to rate a vehicles efficiency. There are too many variables when doing tests on different days and even different times of day. A tail wind on one day could make a huge difference on a headwind another day. Case in point, when they tested this same exact truck configuration last year on the same loop towing a 29k fifth wheel horse trailer, they got 8.7 mpg.

If you go off of real world data like Fuelly where people post millions of real world mileage(which matters more than this test), the new Powerstroke 10-speed seems to have merely just caught up with the Cummins. Before 2020, the Powerstroke F250 averaged 14.5 mph while the 2500 Cummins averaged 15.4 mpg. The few 2020 F250 postings(3 members so far) are showing a 15.3 mpg average, but that is too little of a a group still to tell just like the new Cummins 2500. The F350/3500 is harder tot tell because you don't know the mix of DRW and SRW and they are used to tow more than F250/2500s which makes it harder to get a good average.

I would be surprised if the Ford got 30% better MPG than the RAM, but I also don’t think fuelly is as accurate for comparison with these two trucks.

A 2500 RAM has the lower output engine due to the transmission doesn’t it? Does the HP engine with the Aisin get the same MPG as standard engine with the 68RFE?
