That site says: Under the new rules, combined fleet fuel economy will have to increase to 29.7 mpg for the 2012 model year, ramping up to 34.1 mpg by 2016. The passenger-car slice of that number goes from 33.3 (2012) to 37.8 mpg (2016) while light trucks increase from 25.4 to 28.8 mpg. The current standard is 27.5 mpg for cars and 23.5 mpg for light trucks.
My only question here is, what are they calling a light truck? A ford ranger/dodge dakota/chevy colorado? Even those trucks would be lucky to hit the current 23.5MPG standard. I also wonder what they are going by, highway mileage? I'm pretty sure that's highway mileage and I think thats BS because a lot of these trucks have a much higher highway mpg than the city, so on the highway thats fine (especially using the variable piston use thing like chevy has, which I have heard makes them pretty good on fuel use), but for any city drivers, it does nothing for them. I really don't get it, I'd like to see a more defined writeup of this standard, see the exact things that has to be met. I'll keep digging.
