While it is a little crude, I have completed the EPA estimates for all cars from 1985-2006. You can find your car here:
I have no plans on adding much more data to it. The entire purpose of it is to get an idea where your car sits in comparison to the EPA estimates.
Please take note that the EPA changed the way it reported estimates beginning with the 85 model year. They began reducing the measured highway results by 20% and the city results by 10%. That was in response to the public outcry that the estimates were unrealistic. Now it seems that we are in for another round of adjustments next year, due to a similar public outcry.
One example of this is the 84 CRX 1.3 (54/67)and the 85 CRX HF (49/54). You can see that the estimates dropped by 20% . Unfortunately the DB that Matt made does not have the 84 CRX.
To add the EPA profile to your particular vehicle, simply visit the garage page for each vehicle and click on the link that says, "Change this vehicle's EPA profile."
W00t! I'm EPAified
Hmmm. Now that the EPA estimate info is there, along with the gaslog average, wouldn't it be easy to display, along with the average MPG, the % under/over EPA combined? If I had an "EASY" button, I would do it for you. I saw several on ebay. Maybe I will get one. ;-)
