The reason for this is because I found a high dgree in variance among what dealers are putting on the stickers. For instance my 2008 says 45 city and 48 hwy but my friends 2007 sticker from the same dealer says 57 city 60 hwy?
Yes, there should only be two versions. THe EPA updated the method for testing for all cars in 2008, yeilding the 46 city, 45 highway which I think is fairly accurate for moderately agressive drivers. Check again on the 2007 sticker. I will be very surprised if it doesn't read 60 city, 51 highway.
