There's an interesting article in Jalopnik about how cars would look if instead of the integrated bodies that they are, they had been manufactured separately as engines and carbodies, in analogy with the separation between the horse and the buggy.
A very interesting article, and it certainly would have advantages.
My father lost a whole truck to an engine fire, some type of emergency engine release and pushing them apart could have saved it.
This would really help farming if you can move an engine between vehicles and farm equipment.
I wonder what it would mean for auto safety if the engine and body break apart in a wreck instead of crumpling into each other?
I don't think the oldest engine designs would go away, I can see a market even today for engines that can attach to animal drawn wagons and farm equipment.
For some of my motorhead friends back in the day motors were effectively seperate. They would swap engine as casually as most people have their tires changed. I recall one who sold a muscle car with a high performance engine, the buyer to return the next morning with the money. Between supper & the ten oclock news the seller pulled the race engine & installed a factory stock motor. Painting it to match along the way. Gotta love quick disconnects & a good set of tools.
It would, I think, take all of fifteen seconds for someone to say 'hey, why don't we put the driver on the motor unit, and get rid of these complex linkages?'I would think even if the first vehicles were built with separate motor and driver/passenger units it wouldn't be long before someone got the idea it would make sense to combine them together.
