Pollution Control
When all these muckety mucks start spouting off about how much better gas mileage the vehicles get in China compared to the U.S., they don't bother to take into consideration that cars in the U.S. are loaded with fuel consuming pollution control devices. Look under the hood of a car in the U.S. and you don't see the engine, you see all the pollution control crap. Look under the hood in China, or Asia as far as that goes, and all you see is an engine. All the power they generate goes directly to the drive wheels, not wasted on power robbing pollution control devices....
