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.
