Can you point me to any of them? The only ref. I have is the EPA's:

. An extra 100 pounds in your vehicle could reduce your MPG by up to 2%. The reduction is based on the percentage of extra weight relative to the vehicle's weight and affects smaller vehicles more than larger ones.

Thanks. Info like that deserves its own thread. Thread-splitting...
