2017 Ram 1500 Ecodiesel HD

With Ford expected to add a diesel and ten-speed to their aluminum-bodied F-150s for 2017, Ram engineers are working hard — likely focusing on many different bottlenecks, rather than a single technology.

When 2018 comes, there will also be a “commercial” version of the Ram 1500, with enhancements for heavy duty work cases. The chart below suggests that a Ram Commercial version of the 1500 will appear earlier, but that would likely show up separately if it were true. (The years appear to be calendar years, not model years.)

There are also hints of the diesel gaining in towing capacity, possibly through gearing, calibration, and possibly upgraded internal parts upgrades could push it beyond 10,000 pounds (it’s currently rated at 9,200).

It is unlikely that the eight speed will jump to ten any time soon. ZF’s chief executive already dismissed that, saying the rewards were lower than the costs — and this is coming from a company that supplies Rolls-Royce.

  • I've wondered why Chrysler bothered with converting the ZF to a nine speed unless it was for CAFE. I would have thought the eight speed with six under and direct drive ratios along with two OD ratios would make more sense in a TV than the nine speed with five under drive and direct ratios along with four OD ratios anyway.
  • Is this all because the little diesel weighs a lot more than the 5.7, or are other heavier components involved too? If it's so heavy, how is the fuel economy improved, seems like magic math gets involved.
  • I don't think you will see the Ecodiesel towing more than 10,000 lbs since there is not much more gearing you can give it and still being economical. The 9,200 lbs it is rated for is with a 3.92 gear ratio and an 8 speed transmission. If it can't be done with that then I don't think making the rear gear shorter is going to do much. They would have to pump up the power output of the Ecodiesel to get it done.

    Also, the only Ecodiesel rated for 9,200 lbs is a seldom bought stripped down 2wd regular cab. The more common crew cab 2wd is rated at 8,800 while the crew cab 4wd is 8,600 lbs.
  • I hope to see some of the major changes for the 2017 MY. I plan on buying a 1500 series pickup in about 18 months and the Ram Ecodiesel is at the top of my list.

    No point in a 10k tow rating when it has less than 1k of payload.

    Do you happen to work in the tech center?... If so give a wave to OU next time you drive by, ahh the good old days.

    The JGC Like ALL current FCA NAFTA vehicles is an all electric HVAC control system. In a stop event what you're hearing is the recirculation door moving to 50% in order to prolong cabin thermal comfort in the vehicle during the stop.

  • Interesting info Don. What would the characteristics be that the commercial version will have?

    Not a big fan of the stop/start feature. Had a Grand Cherokee rental for a week which had it. Didn't like the slight shutter you felt when it restarted. And since there is no vacuum when the engine is off, the ventilation flips to defrost at every stop light. Maybe it's just me but I found it irritating.

    I agree with Gordonthree, really need to increase the payload. That will allow it to compete with ALL 1/2 tons for payload, It has them all pretty well beat on MPG.

  • Hmmm... I'll likely be getting a new Ram sometime this year, as I'm almost done with borrowing my current one from Fiat.

    I'd like to see them push the payload rather than the towing cap. My Outdoorsman has the 10000 lbs rating with its Hemi and 3.92 rear end, but the payload is so tiny, I couldn't come close to that weight unless it was just towing steel i-beams or something on a low profile trailer?
