Fact 1: China's current mpg standard of 36.8 mpg is higher than what we have in the U.S., so it's not as big a leap to 42.2.Full details here.Yes, 42.2 is still better than 35.5, but now you know a little bit about why, and why the simple questions rarely have simple answers.
Fact 2: The national fleet in China is mostly made up of small cars that are inherently more efficient than American land barges.
Fact 3: Fuel economy is used as a basis for taxes in China, so consumer demand for smaller cars exists in a way it doesn't here in the U.S.
