New EPA mileage standards

[marcus]

wait a minute i understand the horsepower new measurement conversion but how can they change calculation on gas mileage..if ur travelling 40 m/gal how would that change it..i dont get it.. unless they calculating mileage by a person pushing the car to red line all the way thru then that will make sense..

They now base their estimates on how most people actually drive rather than how they should be driving. Hard acceleration, hard braking, tailgating, speeding, excessive idling, etc. all lead directly to low mileage/increased emissions, but that's exactly how most folks behave on the road today.

What I find funny is that while the EPA is busy dropping their numbers my own fuel efficiency with my Yaris keeps raising. I got 48 MPG on my last tank.

I'm still getting good mileage, all city driving at 35 mpg, and when I do about 120 miles on the highway to Denver and back along with my city miles I get 38 mpg. So I only could imagine if I was doing mostly Highway miles it would be around 45 mpg.
