You mentioned cars and then went on to throw out two examples, one a manual 80's Accord versus a modern automatic Civic and then your BII. I merely pointed out the MPG is more than just transmissions, its other things as well. Another would be the FJC which has the manual at only at 2 mpg disadvantage. Hardly the 4+ you were referencing in an earlier post. If the transfer cases were the same, I bet they wouldve been neck and neck.
My point with the emissions equipment is to disprove the claim that older cars were more efficient than newer ones. Increased emissions equipment does reduce mpg but in trade off for having a cleaner, less polluting burn.
As for an advanced 'overland in the US' truck, whats wrong with a modern automatic? Why is everyone so afraid of them? Do they have sensors? Absolutely. Are they better than the manual transmissions available right now? Absolutely. They handle more power, are better at selecting the right gear for efficiency and have more gears to choose from. The US is not Africa where you might not be able to get to a fully prepped shop. There was just a story about the 'loneliest place' which really was not that far from a paved road where you could get a tow to any number of dealerships for a repair. Yes, an automatic will probably need a rebuild before a manual transmission will but thats not going to be for at least 100k miles from new. Not to mention that an automatic delivers better control and the slip is actually beneficial off road (since we are talking about 'overland travel', this might not matter). With so much time spent on hard pack or tarmac, where does the supposed 'toughness' of a manual actually come into play?
CR tested the Scion xD at 34 MPG (MT) and 28 MPG (AT) mixed driving (and is just one example). However that's here nor there as I don't think you'd get very far down a rugged dirt trail in a xD.
Less miles traveled per gallon burned = less fuel efficient (funny I never would've guessed anyone would ever question this concept :Wow1: )
But anyway... While you are taking your automatic trans to your fully-prepped (to take your $$$) shop to be rebuilt at ~100K (seems like 150K should be more typical, but whatever), I'll be out having some fun exploring a trail (or out on the road) rowing my gears probably well past 250K and beyond.
Cheers.
