DOHC is a simpler design than SOHC and will usually have fewer moving parts and less reciprocating mass than equivalent SOHC implementations. This usually more than offsets the increased rotating mass and total mass allowing for a more efficient and longer wearing engine, yes. This does not mean that cars in general will become more fuel efficient. There are many other technologies coming into play that do much more to reduce fuel consumption, but in developed nations and especially the US, regulations requiring ever lower emissions and vehicles that do more to protect occupants in the event of a crash make cars less and less efficient and drivers less and less efficient as well.
Most cars are smaller and more fuel efficient than American cars. Colder than most parts of the US. Smaller area and less population density. Different form of government. A LOT LESS PEOPLE. Different language. More snow than places in the US that get snow.
