Have they demonstrated themselves to be more problematic? I’d love to see evidence of that. The Coyote is on Gen3 and the 2nd gen was a cock up. The 8-speed ZF in the ram is in Everything and might just be the best transmission around. what about more gears makes it bad?
The 2.7 has a great track record thus far, and revisions to engine design are exceptionally common amongst ALL engine types And manufacturers. What about it do you think makes it more expensive to repair? A turbo? Have you ever looked inside a modern DOHC engine timing cover? Those “simple” V8’s aren’t very simple. long chains, VVT intake/exhaust, etc. lots of scary stuff to go wrong. Even modern pushrods from GM have cylinder deactivation etc.
what will really bake your noodle is that when you look at reliability overall of modern engine design, it’s EON’s better than the “simple, reliable” designs of the past that you seem to be yearning for.
yes, Modern vehicles with complicated engine doohickeys, spinny spinny fans, and “too many gears” are lasting longer than the ancient slush boxes and domestic small blocks of the past. The future is now, old man.
