    No, you’re not understanding me correctly. Mostly because I misspoke, so that’s on me, not you.

    The contact patches I was talking about are the corners of the rectangle. Everything between the wheels is the footprint.

    The area of the footprint basically determines the minimum MPG you can have. (The more complicated point is that it is related to all the vehicles you produce rather than a specific minimum, but that overcomplicates the issue. The point is that CAFE standards provide strong incentives for manufacturers to increase the “footprints” of their vehicles. The larger the footprint they can claim, the less MPG improvement they need to make. So, longer and wider wheelbases.
