New MPG Ratings

Buyers of new 2008 vehicles will notice that the posted MPG ratings for cars will be a lot lower due to new MPG Ratings. The EPA recently revised the methods for estimating vehicle fuel economy to better match the driving styles and conditions. Due to tests based on different speed limits, A/C usage, and temperatures, the new MPG estimates can be anywhere from 8-20% lower than previous estimates. The same applies to Hybrid Cars and those may have more of a difference based on the high estimates that they stated before. This will definitely make people more conscious of what kind of car people will buy.
