Maybe we missed your point. We thought you meant US brands of cars have poorer fuel economy than foreign brands.
Pawlowski's comment is "ratings for domestic and foreign cars of the same size and there is little, if any, difference". The only accurate conclusion is that some people in the US buy less economical cars - either foreign or domestic. OK. So what? I can't change what America buys and your complaining won't change it either, particularly when you are complaining to a group that drives Saabs. Have you heard the expression "Preaching to the choir"? I can only do my small part. My new car gets 35 mpg (6.7 l/100km), seats 5 comfortably, uses low-cost, regular octane gasoline, and is classified as an Ultra Low Emissions (II) Vehicle. BTW, it is a US brand: Ford.
Did you actually mean that cars sold in the US have poorer fuel efficiency? That begs the question: Poorer efficiency than what? Cars in Europe that require more resource consuming and expensive premium fuel? Cars from around the world, including Europe, that emit more than double the pollution allowed by US standards? Cars that don't meet US safety standards and would be as bloated with weight as US cars if the safety equipment is added? Cars (particularly small ones) that foreign manufacturer's won't ship to or can't legally sell in North America?
