How we pick these
Most "best MPG for the money" lists use MSRP or guess at prices. We don't. Every car here is matched to its real median asking price from live US listings, then ranked by its official EPA MPG — so the list reflects what you'd actually pay and what you'd actually burn in fuel. The top pick, the Hyundai Ioniq, saves roughly $969/yr in fuel versus an average 26-mpg car.
