It's definitely about small engines and electric tech. Where are all those small turbo motors? Unless you mean FIAT cars which is nearly going out of business in North America?
Dodge has what, a minivan and the Challengersaurus/Chargersaurus. Chrysler has a minivan and the 300. RAM? Nope! So far no small turbo engines in their main brand lines (other than nearly non-existent sales of FIAT cars).
That leaves Jeep, which only has the 2.0L I4 turbo & that FIAT 1.6 in the Renegade. Not exactly brimming with variety or tech to be honest. The Pentastar only makes 305hp / 269 lbs-ft of torque in the RAM, which is slightly better than the most basic work truck base V6 offered by the competition, with only 10% take rate! Again, not enthusiastic about it and certainly not enough volume.
As for Ford, they don't like cylinder deactivation (neither do a lot of RAM owners from what I've seen so far). Hasn't hurt their mpg on the 5.0 compared to the 5.7L has it? You named the F150 hybrid, they will have a full electric within the year. GM has an electric Hummer, which will pass that tech down.
RAM has what? E-Torque, ok.
The merger was about gaining market share (becoming 4th largest) and taking advantage of scale. You just discarded all FCA's small engines and then said "yup, no small engines". That's priceless.
Your other arguments are equally bizarre. Take rate is small, therefore engine is "behind in tech". That's a wild jump.
Ford doesn't offer cylinder deactivation because a tiny minority of Ram owners prefer to disable it? OK then!
Ford doesn't even offer cars anymore, don't go laughing at FCA who at least still has a product line.
My truck literally decimates my brothers 2014(?) F150/5.0 in mpg. We're talking at least 15 to 20% worse in normal driving, and probably close to 30% when we hit the freeway. He is down 2 gears, so there is that, but I'm also a little heavier. And I drive with MDS disabled. I'd say that's a pretty nice showing for the Hemi. Course anecode is not data, but the 5.0 is no fuel efficient princess.
Ford's electric truck was bought, not developed by them. Ok, half point. You lose a half because it's just as easy for Ram to do that tomorrow, if they don't already have their eye on this. "Behind in technology" is a very large stretch, and definitely does not apply to their gas engines. GM has done far better in this regard, they really do their own electric and do it best next to Tesla.
I'm not trying to bash Ford. But the claim that Ram/FCA is behind (especially the gas engines) is just nuts. They are very competitive.
